Carnivores or Omnivores, Are Spiders?

Spiders are omnivorous creatures that consume other spiders as well as flies, moths, cockroaches, fleas, and other insects. Some species are large enough to consume tiny rodents, amphibians, reptiles, snakes, and birds of all sizes, including the tarantula and the Goliath bird eater.

Spiders catch prey in a variety of ways. Some of them weave webs, while others hunt actively, while others wait in burrows or on bushes to pounce on a possible victim as they pass by. In order to break up the catch while feeding, spiders have serrated edges in their mouths that move from side to side. Prior to swallowing, digestive enzymes are injected into the prey.
