Scorpion Digestion
Digestion for Scorpions begins outside the mouth. The food is semi-digested by digestive juices that are supplied to the preoral cavity by the gut, before it enters the scorpion's mouth. Setae, which is in the preoral cavity, filters indigestible material such as prey exoskeleton. These indigestible particles are matted together and expelled. Food passes from the mouth to the pharynx, to the esophagus, to the mid gut, to the hind gut, and is finally expelled through the anus. Drawing food into the body, the muscular pharynx acts as a pumping organ. Excretion wastes are expelled through the anus with feces.
