Spider

bugs · builders · arachnids

Silk spinners. Spiders have special body parts called spinnerets that squeeze out silk, which they use to build webs, wrap food, and even glide on the wind.

Eight legs. Spiders are arachnids, not insects. One way to tell? They have eight legs instead of six.

Almost everywhere. Spiders live on every continent except Antarctica and have made homes in nearly every land habitat on Earth.

So many kinds. Scientists have recorded over 53,000 different spider species, making them one of the most diverse groups of animals alive.
