Spiders are not insects. They are actually invertebrates which mean animals without backbones.
All spiders have eight legs and poisons. Spiders can live on every continent except Antarctica. There are over 44,000 known kinds of spiders. Spiders are found in every hole o f houses. Spiders are unique among animals that many of them spin webs out of silk. The webs catch insects to be eaten later. Larger spiders, such as wolf spiders, huntsman, and tarantulas, attack insects rather than spin webs. Most spiders eat insects, but some of them such as tarantulas and larger spiders will eat small lizards as well. Many people fear spiders. Most spiders, however, are totally harmless to humans and are actually useful because they eat other insects or pests. Even the largest tarantula, the Goliath - bird eating spider, is harmless to humans. It is said that a tarantula’s bite is about as painful as a bee’s sting. Some spiders, however, such as the black widow spider, are dangerous to humans. Their bite can kill people within a few days without immediate medical attention.
