Spider
Spider Digestion
- Food is digested outside the mouth
- Some spiders chew their prey as they cover it with enzymes
- Others bite the prey and pump digestive enzymes into it before sucking up the liquefied internal tissues
- The mouth leads into a narrow passage, the pharynx, which leads to a sucking stomach, which is part of the midgut
- The midgut has a variable number of blind extensions, or ceca, that extend into the first segments of the legs
- At the end of the gut a cecum connects with the hindgut before opening through the anus
