Spiders eat other insects, like flies, moths, cockroaches, fleas, mosquitoes, and even other spiders. Some species are big enough to eat small rodents, amphibians, lizards, snakes, and small birds, like the tarantula and the Goliath bird eater.
Spiders use various techniques to capture prey. Some spiders make webs, some hunt, and some hide in burrows or on bushes until a possible victim walks by. Spiders’ jaws have toothed edges that move from side to side to break up their food as they eat. Before swallowing, enzymes are injected into the prey to help it break down food.
