Spiders belong to a group of animals called arachnids. Unlike insects, they have eight legs and no wings. There are only two parts to their bodies and they usually have eight eyes.
Many spiders hunt by building webs to trap insects. These webs are made of spider silk – created by the spider using spinnerets on the end of their abdomen.
Some spiders, like tarantulas, inject poisonous venom into animals that threaten them.
