Do Spiders Eat Their Babies? Spiders that Do & Reason Behind it.

Is the myth true that spiders can eat their babies?

If so, why would Spiders try to eat their own babies & Which Spiders are known to do this?

There are thousands of different spider species, and some of them as you might know can look quite terrifying, but are they really as bad as they look and can they eat their own Babies?

Why Would Spiders Eat their own Babies?

The first reason why a spider would eat their babies is for nutrients that help them to survive in the wildlife which we all know is fairly rough.

The second reason why spiders could eat their own ‘blood’ is that spiders do not have brains, they only have nerves that connect to each other.

Therefore, they can’t feel empathy, or any type of emotion/connection to other spiders even though they can be from the same species, or worse -Their own Babies!

The third reason for a spider to eat its babies is out of hunger. If it was not able to have a meal before giving birth, it can eat its own baby spiders out of pure survival.

How Often Do Spiders eat their own Babies

Is it a common thing for spiders to eat their own babies?

Well, it is not that common, specialists say that spider cannibalism (the act of a spider eating another spider)  is very rare and spider mothers will do this only out of desperation or if they simply have mixed up the babies!

There is a major difference between male and female spiders. Female spiders are known for their aggression. Some of the female spiders eat their partners.

This is the reason why they are more susceptible to eat their own babies rather than the male spiders.

Given the chance, however, a male spider will also eat spider babies if he is starving – Most Spiders Die out of hunger without ever having had a meal…
