Spider have been on this planet for 400 million years. They are predatory insects that eat other insects (even other spiders) and small animal. Most spiders are harmless to humans. The most deadly spider are the black widow spider, the yellow spider, the hobo spider and the red legged spider. These spider have enough poison, or venom, to kill with one bite. Spider are able to control how much venom they inject into their prey. In fact, they can even bite without injecting any venom. This is called a dry bite.
