All about Spider Emotions (Do they Feel Pain?)

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.
