Spiders are arachnids with eight legs and six or eight eyes. There are over 40,000 different species in the world. Some live in warm climates while others prefer the cold. Spiders spin webs made out of silk. Some species use their webs to catch their food while other prefer to leave the web to hunt. Most spiders prefer insects while others are herbivores. Spiders are unable to digest solids. They secrete enzymes to liquefy a meal prior to eating. Spiders typically only bite humans in self-defense. Some species are poisonous. If you are uncertain of the type of spider that bit you, try to take it to the doctor with you in a sealed container. Black widow spiders, western black widow spiders, brown recluse spiders, desert recluse spiders and hobo spiders are all poisonous and found in the United States.
