Spiders' lungs are shaped like an open book.

Jumping spiders can jump up to forty times their own body length.

Spiders are creatures that have 8 legs, have no wings or antennae. They have 2 distinct body parts called the thorax or head and the abdomen. Spiders have an exoskeleton, meaning that their skeleton is on the outside.

Webs get dirty and torn, so lots of spiders make a new one every day. They don't waste the old one, though--they roll it up into a ball and eat it!

The average person will encounter some 50 different kinds of spiders in
their lifetime.

On average, people fear spiders more than they do death.

Only the female black widow spider has a poisonous bite. The male spider's venom is not poisonous and it does not attack its prey.
