Spiders are arachnids, not insects. They have eight legs and two body segments, while insects have six legs and three body segments.

There are over 40,000 different species of spiders found worldwide, with varying sizes and colors.

Spiders produce silk from their spinnerets, which they use to create webs for trapping prey, protecting their eggs, and even for transportation.

Spiders are predators that primarily feed on insects and other small animals. They inject venom into their prey to immobilize it before consuming it.

Some species of spiders, such as the black widow and brown recluse, are venomous to humans and can deliver a painful or even lethal bite if provoked. However, most spiders are harmless to humans and play a crucial role in controlling insect populations.
