How Earthworms Breathe and Other Biological Facts

Earthworm in grass

Earthworms are amazing creatures. They can survive in the dirt, breathe through their skin, reproduce on their own and eat without teeth. Read on to learn more facts about the humble earthworm.

How do Earthworms Breathe?

Earthworms breathe through their skin and their lungs. Their skin is permeable, which means that gases can easily move in and out of the worms’ bodies. Because earthworms are invertebrates, they don’t have a diaphragm or ribs to force air into their lungs. They use muscles that surround their body cavity to push oxygen throughout their bodies.

Gases and water can easily move into and out of the skin and body cavity because of the way that they’re shaped. Also, their cells are closely packed together, which is why it’s easy for gases to travel through them.

Earthworms have a closed circulatory system, so oxygen doesn’t move around their body in blood as it does in mammals. Instead, they rely on movement to carry oxygen throughout their bodies. They move by contracting muscles, which force blood through their bodies. This system is called “peristalsis.”

As the earthworm pushes itself forward, its skin touches the ground for a fraction of a second. The oxygen that’s in its body easily passes into the soil because it doesn’t have any other molecules to get in the way. Then, the earthworm’s body starts to absorb oxygen into its tissues.

While this process is happening, carbon dioxide in the worm’s blood diffuses out of the worm and into the surrounding soil.

Do Earthworms Have Brains?

The answer is no. Earthworms don’t have a centralized brain as other animals do. Instead, there’s lots of “processing power” spread throughout their entire body!

Each segment of an earthworm’s body contains tiny little ganglia, which act as tiny brains. As long as one section of the worm survives, then it will regenerate its body and brain over time because each part knows how to function on its own.

Do Earthworms Have Eyes?

The answer is no. Earthworms don’t have eyes, but they’re very sensitive to light. Some worms are able to sense the difference between light and dark, which allows them to avoid being exposed to sunlight or beneath the soil’s surface during the night.

Earthworms more rely on a sense of touch. One of the ways that earthworms sense touch is through their bristles (or setae), which are positioned all over their body surface. The bristles give the worm information about its environment so it knows when to move away from something potentially harmful or beneficial, like food or shelter.

If one or more of these bristles is touched, the worm immediately withdraws. Bristles are also used to assist the worm’s movement. It’s hard for an earthworm to move its body without some sensory input from these bristles. Earthworms have a sophisticated nervous system that helps them figure out how to use this information appropriately.

Do Earthworms Have Ears?

The answer is no. Earthworms don’t have ears, but they do have a cuticle made of chitin. Earthworms are very sensitive to vibrations in the ground. Their chitinous skin helps them detect small vibrations, which signal that something may be creeping along the surface or burrowing through the dirt.

This allows earthworms to quickly escape if they need to!

Do Earthworms Have Noses?

The earthworm does not have a nose. In fact, the earthworm has no sense of smell at all!

Do Earthworms Have Mouths?

Earthworms have a mouth and a pharynx. Their mouths are located at the front end of their body, which is where they ingest soil and organic matter. The food goes into their esophagus, which leads to their pharynx. Gas exchange occurs in the pharynx since it’s lined with tiny blood vessels that allow oxygen to go in and carbon dioxide to go out.

It also serves as an important part of their digestive system; after the digested material leaves this section of their body, it gets mixed with fluid from glands that produce digestive enzymes before getting pushed into the intestine, where nutrients are absorbed.

Do Earthworms Have Teeth?

No, worms do not have teeth! There are tiny bristles on their mouth called “trophi” which allow them to move food towards their throat where it eventually ends up in their stomachs.

They get their nourishment by absorbing organic matter through the surfaces of their bodies. Since they’re unable to chew on most food items, worms easily digest things like leaves, decaying plants, animal manure, compost piles, rotting logs and even fallen tree branches. Some scientists believe that earthworms actually help decompose these types of materials naturally because they speed up the process.

Do Earthworms Have A Heart?

Earthworms have an aortic arche that helps circulate blood throughout their body. This helps them ensure that all of the oxygen and nutrients they need are sent to the right places in their body, while any carbon dioxide or waste is carried away.

FIve of these aortic arches pump throughout the worm’s body.

Do Earthworms Have Bones?

No, earthworms don’t have bones as we do. Instead, they use a hydrostatic skeleton to support themselves as they crawl through the ground and push through the soil. This means that the worm’s muscles push against its skin to create movement – not an internal structure like bone.

Since there’s no bone inside of them, worms are able to squeeze into very small spaces where other animals might be unable to fit and invade their homes (and eat all of their food).

Do Earthworms Lay Eggs?

Earthworms are hermaphroditic, which means that they contain both male and female reproductive organs. They’re able to reproduce by themselves but usually need another individual to mate with in order to produce viable eggs or sperm. Then, they can fertilize each other’s genitals internally! Once the worms finish mating, each of them lay one egg at a time.

These eggs are placed onto the surface of their mounds so they have some protection before hatching into tiny earthworms called larvae. The mother worm does not take care of her babies after she lays the eggs on top of her mound; instead, these new little ones crawl away from the nest when they hatch so they can live independently.

Final Words

Earthworms are an essential part of the environment and provide many benefits to humans. They help organisms break down organic matter including leaves, animals manures, rotten logs & fallen trees; they do not have teeth or bones; worms are hermaphroditic and breathe through their skin.

Hopefully, now you can fully appreciate earthworms and their strange but fascinating biology.

All about Spider Emotions (Do they Feel Pain?)

Spider looking forward

Spiders are fascinating creatures that usually invoke terror and fear into humans that come across one. But do the same feelings and emotions apply to the spider? Read on to learn about that and more.

The Spider’s Nervous System

Spiders have a rather simple nervous system which, like that of insects, is divided into a brain, ventral nerve cord, and an array of connected ganglia. Spiders also have several pairs of ganglia in their legs. The type of spider determines the exact number and location of these leg pairings, but there are always at least three or four pairs.

This arrangement makes sure that sensory input from one side of the body is processed by the central nervous system before information from the conflicting half-side reaches it. This ensures a faster reaction to stimuli.

How does this work? In most cases, specific stimuli will occur on one side of the organism’s body or another. When such a thing happens on one side, certain information will be sent to the brain through a leg ganglion.

The information is then transferred from one ganglion to another along the ventral nerve cord until reaching a pair of ganglia in the other leg on that same side. These two interconnected ganglia signals “turn around” and follow the same path back to the first pair of ganglia which also transfer their message across until it reaches its original location where it can finally reach the spider’s central nervous system (brain).

This chain reaction happens very fast and ensures faster processing by the central nervous system.

Do Spiders Feel Pain?

No spiders do not feel pain, they have been shown not to have nociceptors. Nociceptors are nerve endings that send pain signals from the body to the brain when stimulated by certain agents such as heat or certain chemicals.

Without these receptor cells, insects will not perceive painful stimuli and behave accordingly. It can thus be safely concluded that since spiders lack nociceptors, they don’t feel pain.

Even if a spider loses a leg?

No pain will be felt by the spider, even if the spider loses a leg. In fact, it can even regrow that leg if it has at least one more moult left in its life cycle.

The new leg will be thinner and shorter than the original and will take another two or three moults until it’s back to the original size and shape.

Do Spiders Feel Fear?

Spiders don’t have brains in the same sense that mammals do. They are not “scared” of anything because they don’t have the means to be frightened. Their central nervous system is made up of a diffuse net of interconnected cells which process sensory input from their surroundings.

This network cannot produce emotions since it lacks any semblance of an evaluative capacity. That’s why spiders can’t feel fear, fear being an emotion.

One thing they do seem to be good at, however, is detecting certain chemicals released by other insects when these are under duress. When ants get stuck to glue, for instance, it seems that there are certain substances released by them which cause alarm among other ants nearby leading them to rescue their trapped peers.

Arachnids can take advantage of this information by preying on these insects that are stuck.

Do Spiders Feel Love?

Spiders don’t have the capacity to feel love, or any other emotion for that matter. While they can coordinate hunts with each other, it should be noted that this doesn’t involve any emotional input. They are simply following a pre-ordained pattern which has proven to be an effective means of catching prey.

There’s no evidence that there is an emotional component involved in their decision-making process.

All spiders do hunt alone, each spider having their own distinct territory within which they capture insects and other arthropods. These are not shared so if one spider were to offer to share its meal with another, this would be completely anomalous behavior on its part since there’s no reason why two individuals would need to share food. Spiders are thus not social.

The only apparent evidence of social behavior in spiders is the fact that they will sometimes form silken nests together after mating, but it’s unclear whether this is done for mutual protection or pleasure. This isn’t an indication of any emotional bond between them since they don’t have the means to feel emotions like love.

Do Spiders Love Their Babies?

Yes, spiders love their babies (spiderlings) but in a different manner than humans would.

They don’t feel any need to nurture them since this is something that happens automatically. The spiderlings will stick close to their mother for some time since they still depend on her until their first moult.

After this, they will be on their own and the mother spider won’t see them again for several years. She’ll die long before they reach adulthood and start mating themselves.

Final Words

Spiders are emotionless creatures that cannot feel pain or any other emotion.

They will attack anything that gets near them but it’s just the result of their predatory instincts being triggered not because they are scared of being hurt.

Sounds cold but that’s just mother nature at work.

Weird Ant Death Facts

Two ants

 

Ants are constantly on the move, looking for food to bring back to their nest. Unfortunately, ants are often hurt, lost, or killed while they’re away from home. Discover what and why ants do when one of their colony members dies.

Why do Ants Carry Dead Ants?

There is actually a term for this kind of behavior that’s not only seen in ants but other insects as well. It’s called Necrophoresis.

Necrophoresis is when an animal moves a dead or dying conspecific to a location where it might make it easier for other animals, usually predators, to eat them.

Ants carry their dead because they are trying to prevent their colony from becoming infected by disease or with something that might harm or kill other ants.

This behavior is most likely an instinct due to the fact that it has been seen in all types of ants. It can also be attributed to their highly social nature, which would make them care for their dead more than they would for themselves because ants live in colonies with a queen ant and workers.

Ants also practice necrophoresis because they want to get rid of waste, such as the dead ant’s body, which smells after it has died.

By getting rid of this waste, they can prevent their colony from becoming infected with bacteria or parasites that usually grow on dead animals. This is why ants will dissect them with their jaws before moving them to a location where they might be more easily found by other ants or eaten by something else.

Do Ants Bury their Dead?

Instead of burying their dead, ants usually store them in an ant grave or burial site. The smell of the decomposing body has been seen to attract scavenger beetles who then feed on the dead ant.

The ants also do this because they want to get rid of waste. When the dead ant’s body has been stored away, it doesn’t smell as much as before and can then be carried back into the colony to be eaten by other insects.

Oleic Acid and Ants

Oleic acid is the fatty acid that ants produce. It’s kind of like the chemical compound for ant communication, similar to pheromones which are used to communicate between insects.

When an ant dies, the body will emit oleic acid which attracts more ants to the scene so that they can carry it back into the colony or somewhere else where they can be eaten or just left alone to decompose.

If there are too many dead ants at one time, the ants will actually create ant graves, which are used to store the dead ants so that the living ants have a place to take them.

You can use Oleic acid to your benefit if you’re dealing with an ant infestation. You should not clean up dead ants that have

Do Ants Have Funerals?

No, ants do not have funerals because they don’t bury their dead. Instead of having a funeral, ants usually store the dead in ant graves or places where scavengers can easily eat them so that they can get rid of waste and prevent other

Ants will dispose of their dead in a number of different ways, depending on the species. They may remove them from the colony so they are not associated with death and disease.

Some ants will place their dead inside chambers containing formic acid or other chemicals that destroy bacteria or fungi that might infect the living ants within the colony.

Other ants will store the dead in chambers to be devoured by other ants or even ants that have special jobs such as gardeners or undertakers who take care of dead members of the colony.

A few species, such as the red harvester ant and certain leaf cutter ants, go through a very interesting stage where they dissect the dead ants with their jaws to make sure they are completely clean and free from disease before storing them away in a special chamber.

Do Ants Mourn their Dead?

Ants can feel empathy and can even learn from what they see around them, but ants do not have emotions.

They will care for their dead, but they will eventually dispose of them because it is just what they do.

If you were to look at this from an ant point of view, then burying their dead and removing them from the colony is not something that they really think about.

It’s just what ants do to keep their colonies happy and disease-free, even if they have to put their emotions on hold for it.

Do Ants Eat their Dead?

Even though ants might store their dead away in ant graves, they usually do not eat them. They will only eat the dead when there is a shortage of food in the colony and they can’t spare any more living members to go out and find more nutrients for themselves.

Final Words

As you can see, ants really do go to great lengths to make sure that they are taking care of their colonies correctly. While it may seem like some sort of grieving process, carrying their dead or buying them, it just comes down to the instincts of the ant.

Interesting Facts All About The June Bug (It’s Not Blind)

June Bug

June bugs are also commonly referred to as May beetles or June beetles. These insects belong to the scarab beetle family and make up the genus Phyllophaga.

Native to North America, these bugs can be found in deciduous forests and woodlands where they burrow beneath logs and fallen trees for shelter and food.

Or more annoyingly these little buggers can be found flying around your porch light banging around constantly during the summer months.

Read on to find out just why they do this and much more.

How did June bugs Get Their Name?

June bugs got their name because of the fact that the adult June bugs emerge from the soil at the beginning of the summer.

Female June bugs bury their eggs just a little below the surface of the soil. The larvae hatch within 3 to 4 weeks and will then feed on grass and other plants. They can feed and grow for as long as 3 years! Talk about a late bloomer.

In late spring, early summer, the larvae will grow into pupae and within 3 weeks they will mature into full-grown adult June bugs.

Are June Bugs Blind?

No, June bugs are not blind. They are just very bad at flying and that makes them appear clumsy and uncoordinated.

Instead of their wings moving up and down like most flying insects, June bugs essentially wiggle their wing by curling and un-curling them rapidly in a figure 8 motion.

This method of flying is called “snap-winging” and it’s likely because of their elytra. When they do this, they actually use the hard forewings as a way to break out of their shell by giving themselves room to move around.

So basically June bugs are not very good at flying because of how awkward they are with moving their wings so instead they just snap their wings hoping to gain enough momentum to lift off the ground.

Why Are June Bugs Attracted To Light?

It’s a strange phenomenon because it is the first known instance of an insect being attracted to artificial lights on such a large scale as they all congregate around any source of light at night.

What scientists think might be going on is that some June bugs mistake artificial lights for the moon and that they actually migrate towards them. If you think about it, it’s possible that they confuse artificial lights with the moon because of how bright some of these lights are compared to the Moon which can be so small and far away from Earth.

So if this is all true then basically June bugs aren’t necessarily attracted to anything in particular but they are attracted to bright light sources.

Why Are June Bugs So Noisy?

It’s honestly not very well known why June bugs make noise. The fact is they do make a lot of noise in the summer when you’re trying to sleep at night.

What scientists think might be going on here is that there are two types of male June bugs, one that has a “song” and ones that don’t have songs.

The ones with songs use their song to attract females and it turns out the noise is actually the result of them flexing a membrane in their abdomen called the tymbal which vibrates at high speeds.

Here’s how it works: There is a muscle attaching two plates together, when these muscles contract it causes one plate to snap against the other making that noise.

So basically June bugs are noisiest when they’re trying to attract a mate.

Do June Bugs Bite?

No, June bugs will not bite you. They are harmless and pose no danger to humans and pets because their mouthparts are mad for only chewing plant material.

If one does land on you and you happen to feel a slight pinch it’s only because of their spins on their legs that help them grasp surfaces better.

Where Do June Bugs Go During The Day?

June bugs don’t really get up and go anywhere during the day. Sometimes you might catch one crawling on the ground but for the most part, they’re pretty stationary creatures that sleep under whatever shelter they can find during the day.

The June Bug Life Cycle

June bugs undergo complete metamorphosis during their lifetime. This means they go through four different stages: egg, larva (which is the grub, nymph and finally an adult.

The life cycle starts when a female June bug lays her eggs in the soil and then covers them up with dirt. The eggs will then stay there until they’re ready to hatch.

In about a month-and-a-half the eggs will finally start to hatch and what you’ll see is a small larva that eats anything it can find including other June bugs as well as plant roots, fruits, vegetables and even the bark of trees!

This bug may look scary but what you need to remember is that it’s only a bug in the sense that it has six legs and two antennae. It looks like a June bug but without wings and with a little less hair.

For about 2-3 years, these larvae will grow bigger and bigger until they reach their full size. The next stage in its life cycle is where it becomes an adult.

That usually happens sometime in June when these larvae climb out of the ground and wait for their wings to grow back. After they dry off, they’ll take flight and that’s when people start to notice them everywhere because they can be very loud at night due to their mating ritual.

This cycle will then repeat itself when they lay eggs that hatch into larvae.

What Is The June Bug Mating Ritual?

Similar to many other insects, male and female June bugs will perform a mating ritual to attract each other.

During the ritual, the male will hold onto the female June bug with his antennas while she emits a scent to tell him she’s ready for mating.

The two bugs will then begin their mating ritual which can take up to 12 hours in some cases! It’s not uncommon to see four pairs of June bugs holding onto each other in a big group.

The males eventually let go and afterward they usually die within the next day or two after mating because their internal organs are normally located near their wings which made it impossible for them to pull away without fatally injuring themselves.

What Eats June Bugs?

June bugs are a food source for a wide range of animals including birds, mammals and reptiles.

Some of the animals that eat June bugs include cats, dogs, snakes, owls and hawks.

What Do June Bugs Eat?

June bugs don’t have a picky diet. They just sit around all day and sleep most of the time. However, they do eat whatever comes their way such as plants and fruits, especially those growing in gardens and farms.

Are June Bugs Edible?

Yes, June bugs are actually considered a delicacy in some cultures most famously from China and Japan where they deep-fry them until they turn golden brown. They have a nutty flavor with a little bit of sweetness since most of their organs are located near their legs.

June bugs contain a lot of protein and very little fat making them a great source for consumption. They also have iron, calcium, and other nutrients making them a healthy treat, at least to some.

Be careful though if you have a hankering for some fresh uncooked June bugs. June bug consumption has been linked to outbreaks of an infectious form of meningitis. This is because the bacteria living in their gut are what causes this disease.

The good news is that there was only one reported case of June bug-related meningitis in 1999. There’s no reason to fear June bugs unless you tend to eat a lot of them while ignoring the safe cooking instructions.

Are June Bugs Considered Good Luck?

In some cultures, June bugs are considered a sign of good luck because they symbolize friends or family visiting soon.

In other places, however, it’s just the opposite. People consider June bugs harbinger of bad things to come and try to get rid of them as quickly as possible. They can wreak havoc on crops and gardens.

Final Words

So there you have it! June bugs are just harmless bugs that aren’t much of a threat. They’re mostly seen as a nuisance since they can easily reproduce and eat all the fruits in your garden but nothing that would kill you.

What Do Grasshoppers Eat And Much More

Grasshopper eating

Grasshoppers are insects belonging to the suborder Caelifera in the order Orthoptera. They are sometimes confused with crickets, which belong to an entirely different suborder ( Ensifera ). Grasshoppers are typically ground-dwelling herbivores that feed on plants and tender foliage.

Read on to learn more about the eating habits of the grasshopper.

What Do Grasshoppers Eat?

Grasshoppers eat a wide variety of plants, including cereal crops and other types of grasses. They also have been known to feed on trees and shrubs. Grasshoppers typically eat during the day, when they can better detect potential predators.

Their eating habits are affected by their environment; in hot climates, for example, they may eat less frequently.

Grasshoppers have been known to eat other insects from time to time, but these insects make up a small fraction of their diet and should not be relied upon in any setting.

What Type Of Plants Do Grasshoppers Eat?

The type of plants that grasshoppers eat varies depending on the species. Some common plants in a grasshoppers diet include corn, cotton, lettuce, clover and various weeds.

The nymphs of the grasshopper eat plants too!

Nymphs look like smaller versions of adult grasshoppers. They often eat leaves, but may also damage or kill vines, flowers and other garden plants. A single grasshopper female can lay more than 100 eggs.

How Do Grasshoppers Eat?

Grasshoppers need to eat every day. They do not have teeth, so they can only eat soft plant material. They use their mouthparts to puncture the plant and suck out the juices. Some species of grasshopper will eat until their abdomen is about three times larger than normal.

How Much Can A Grasshopper Eat In A Day?

About 30% of the body weight of a grasshopper is consumed per day. This number varies based on the size and age of the insect, as well as environmental factors.

But very large grasshoppers can eat more than their own body weight in a single day if conditions are right.

So a typical 100mg grasshopper would typically eat 30mg of plant material per day.

However, this is a relatively high rate of consumption, as many insects only eat about 5% of their body weight per day.

What Can You Feed A Grasshopper?

There are several ways to feed your pet grasshopper. You can offer grains, cereal, stale bread or even fresh lettuce. The grasshopper doesn’t have teeth, so it will grind up the food in its stomach using grit taken from outside.

Keep in mind that some food may be toxic if fed improperly, so only use items that are approved for human or animal consumption.

You can also offer your pet grasshopper leaves, flowers and seeds from healthy plants around the yard. This is an excellent way to dispose of weeds that are growing in your garden. Grasshoppers will rarely eat fully developed fruits or vegetables because they tend to have a bitter taste.

Grasshoppers can gulp down large quantities of food in a short time. Feed your grasshopper no more than an ounce, which is roughly the size of its head.

What are toxic foods for a grasshopper?

Some foods that are toxic for a grasshopper include onion, garlic and chocolate. Other potentially harmful items include artificial sweeteners, tobacco and old food.

What Do Grasshoppers Drink?

Grasshoppers drink water, which they obtain from rain or the dew that condenses on plants. They will also drink from any standing water in puddles or ponds.

Grasshoppers cannot drink milk, soda or juice because they can be harmful. They should not be fed anything with artificial sweeteners in it, such as diet soda.

Are Grasshoppers Good For Gardens?

Grasshoppers are not usually considered to be helpful garden insects. They eat leaves, flowers and other plants in your garden. However, they also eat some weeds that may compete with your vegetable plants or ornamental flowers. There are some exceptions to the rule; for example, certain species of grasshoppers have been known to eat non-native weeds that are harmful invasive species.

Are Grasshoppers Cannibalistic?

Grasshoppers are generally not cannibalistic but can be if they are overcrowded or have limited food sources. A hungry grasshopper may eat a dying or dead member of the same species.

Can Humans Eat Grasshoppers?

Yes, humans can eat grasshoppers. As gross as that sounds to some, grasshoppers are low in fat and high in protein, which makes them an excellent choice for a healthy diet. They also contain important nutrients such as iron, calcium and B vitamins.

In addition to eating the adults, many cultures also use grasshopper egg cases as a food source.

Conclusion

Grasshoppers are herbivores who eat a diet of a variety of plants and crops. Though not typical grasshoppers do eat animal tissues and waste and can show cannibalistic behavior.

Here is a short YouTube video that explaining the grasshopper’s diet:

Over 20 Cockroach Answers You Should Know

Different Cockroach species

In this post, I will cover numerous questions pertaining to the humble cockroach. While almost universally hated throughout the world you can not deny these pesky insects are fascinating in their in own right.

Do Cockroaches Have Brains?

Yes, cockroaches do have brains – but these are very basic and simple in comparison to human brains.

They only have about 20,000 brain cells (compared to the 100 billion humans have), and they do not have any pain receptors.

The cockroach’s brain is in its head, and it has a pair of ganglia in the thorax near the nerve cord that helps it process some of its information.

Do Cockroaches Have Nerves?

Yes, they have nerve cells – cockroaches do not have very much of them though, so when compared to humans they don’t really feel pain as much as we do.

Cockroaches have two major ganglia, also called nerve cords. One is located in their head and the other is located near the tail end of their body.

These help them control movement, but they don’t really give them any sensory information – it’s more like they are “connected” to different parts of the roach’s body and this helps them control movement.

Do Cockroaches Have Feelings?

It is not clear whether or not cockroaches can feel pain. According to their behavior, you could assume they do, but it is difficult to tell for sure due to a lack of research.

Do Cockroaches Have Hearts?

They do not have hearts, but they do have a very long dorsal vessel that carries hemolymph throughout their body. This is more like a system of arteries and veins than anything else though – there is no one part that can be said to be functioning as a heart.

Do Cockroaches Have Eyes?

Their compound eyes are made up of hundreds of lenses (called ommatidia), each one with a specific task. They can see fine details this way.

A downside is that they also see everything from many different perspectives, which makes it difficult for them to recognize what they’re actually looking at.

Do Cockroaches See?

Cockroaches do not have eyelids and can’t blink. This is one reason why they die on contact with insecticides: the chemical gets into their eyes and kills them.

They also can’t see colors, but the spectrum of light that they perceive (which has more blue than red) makes it easy for them to distinguish between dark and light.

Can Roaches See in the Dark?

They can see much better in the dark than we can. Their eyes are multi-faceted, and each individual lens has around 150 lenses to help them detect as much light as possible.

They also have a large number of genes devoted to helping them see in the dark.

Do Cockroaches Smell?

They do not have noses as we do, but they still manage to smell and communicate with each other through the use of pheromones (chemicals that are used for communication).

Additionally, roaches can actually smell in stereo. Each antenna on their body has around 50 smaller antennas which help them detect different smells.

Do Cockroaches Have Mouths?

Yes, they do. They are located on the underside of their body and they open up in a straight line from where their head is to the end of the abdomen.

This might make it seem like they are taking food in through that opening, but this is not exactly correct. The mouth of the cockroach is called a “proboscis”, and it does not always stay in that straight line.

When they eat, the first thing that goes into their mouth is saliva which breaks down food even further. They are very picky about what they will eat though – for example, if there are two similar types of food on the floor (same type of leaf, for example), they will choose the fresher one over the older one.

Do Cockroaches Have Tongues?

No, they do not. However, they do produce a liquid that is similar to saliva and it moistens the mouthparts that are called palps. These palps help them eat food by breaking it down further with enzymes.

Do Cockroaches Have Ears?

Their ears are tiny holes on the side of their bodies. The way they hear is similar to the way moths do, although cockroaches have far more hearing organs than moths do.

Cockroaches have groups of cells for hearing called chordotonal organs and they’re located in the joints between their body parts.

They can sense vibrations in the air, the ground and even on their own bodies. For example, they can actually hear their footsteps.

Do Cockroaches Have Hair?

They don’t have any hair on their bodies. They are almost completely smooth. They do however produce a waxy compound that coats the body and makes them feel smooth/silky. It also helps them to keep moisture in their body (in the same way sweat does for us).

However, some types of roaches do have hairs/bristles around/behind their head and on the lower part of their abdomen. These bristles are sensory organs.

Do Cockroaches Have Lungs?

They do not actually breathe but absorb oxygen through spiracles in their body walls. They also use this breathing method to scent pheromones and release carbon dioxide (similar to us humans). This is why you will rarely see them panting as dogs do – they simply don’t need to.

Are Cockroaches Omnivores?

They are not picky eaters, they will eat pretty much anything that smells good to them.

Their favorite foods are sugars and starches (e.g fruits, bread).

They can also feed on plant leaves, glue, hair/fur/feathers/skin particles, etc. They will not eat wood, and some roaches can’t feed on leaves and such because they have been genetically modified to be unable to digest cellulose.

Cellulose is a carbohydrate found in plant cell walls. Humans have enzymes that break down these carbohydrates so we can get energy from them, but cockroaches do not.

Do Cockroaches Carry Diseases?

They do not actually carry any diseases- they spread them.

Some of the most common infections that can be transmitted by roaches are E.coli (short for Escherichia coli), salmonella, shigella and streptococcus (the last two cause strep throat).

They carry these viruses on their legs and bodies, and also in their intestines.

If you touch a cockroach, it’s possible for its droppings to get under your fingernails. If you eat soon after that, the bacteria from those droppings can end up inside your body as well. It is not very common for people to catch these infections from roaches, though.

One thing that’s good to remember is that roaches do clean themselves like cats do (they lick their legs and such) – this means the droppings on their legs will not be there for long.

Do Cockroaches Sleep?

Cockroaches do sleep, but they don’t have eyelids so they can’t really close their eyes. They will only rest when they are in a dark place where they feel safe, and even then it might be just for a few minutes or hours.

When the roach is resting, its body goes into “stop” mode which means all of its muscles will relax (this doesn’t mean that they are unconscious though).

Do Cockroaches Have Blood?

Yes, they do have blood – it is called hemolymph and it’s actually closer to the blood of an insect than it is to our blood (the color varies depending on what type of food they eat).

When a roach loses a leg, it can bleed because the hemolymph will ooze out. Sometimes they will “bleed” to death this way simply because their immune system isn’t strong enough, and other times it might be caused by a bacterium that enters the wound and releases toxins.

Do Cockroaches Have Bones?

They do not have a skeleton – instead, their bodies are made up of a hard protective shell called an exoskeleton. This surface can be hard or soft depending on what kind of species it is – the harder species will have a shield-like shell, while the softer ones will have a smoother one.

They do not actually need to have bones because their exoskeleton can support itself and their muscles are enough to keep their bodies from collapsing in on themselves.

Do Cockroaches Shed?

Yes, they do shed their skin when they grow too big for it. They will eat their shed skin after doing this though – because the new skin underneath is soft and moist, allowing them to move around much easier than before.

When they are molting, they will be very vulnerable to other predators because they cannot move while their new exoskeleton forms.

Can Roaches Survive a Fire?

Yes, they can. This is because their bodies are covered in a wax-like substance that protects them from extreme temperatures (this wax also helps them retain moisture).

This doesn’t mean that they will not suffer great physical harm if exposed to very high temperatures for too long though – their exoskeletons might begin to melt and this will cause them to melt as well. They can also die if they are burned and not allowed to cool down before too long.

Do Cockroaches Like the Cold?

They can tolerate pretty low temperatures, but they prefer warmer weather. If you’re thinking about keeping them as pets, it is best if you choose one of the species that live in tropical conditions (humidity and high temperature) because keeping them in warm conditions will be much easier than keeping them in cold ones.

Do Cockroaches Have Genders?

Yes, they are either male or female. The male has a “phallus” which can be compared to the shape of a saber tooth tiger’s fang. It is an organ that will transfer sperm from the male to the female during mating.
