Question: How Does A Spider Get Pregnant?

How does a spider mate?

Males don’t possess a penis in the traditional sense. Instead their anatomy includes a pair of appendages called pedipalps, which are much larger in males and have syringe-like enlarged ends.

(Read more about why some animals mate themselves to death.)

How do you kill black widow eggs?

What do spiders do after mating?

Why do spiders kill after mating?

Turns out the motivation for this creepy cannibalism is much simpler. It’s all about size. If males are small, they’re easier to catch and therefore more likely to be prey, say Shawn Wilder and Ann Rypstra from Miami University in Ohio. Big females eat their puny mates simply because a) they’re hungry and b) they can.
