Spider comp

All spiders are carnivorous, Most spiders eat insects but a few of the larger species are big enough to prey on small vertebrate animals like mice or small birds. Most spiders' jaws work from side to side. They have toothed edges used in breaking up the prey during feeding. Digestion starts before any of the prey is swallowed. Some spiders inject digestive enzymes into the prey before they start breaking it up; others secrete digestive fluids as they are breaking the food up with their jaws. The partially digested food is sucked into the spider's alimentary canal (gut).
