Octopus Digestive System
The digestive system of an octopus is a two way opening system including the mouth and anus. Octopi usually feed on lobsters, crab, and shrimp and therefore they have three ways in which they can gain access to their food. The first way is by pulling the prey's shell apart with its suckers, bite the shell open using their beak, or drill through the prey's shell. If they drill through the shell, the octopus would insert a toxin which paralyzes the prey and dissolves the tissue. Then, the octopus may use a toothed tongue called radula to help eat the prey's flesh. Next, they digest the prey in the stomach and then into the digestive sac, which is eliminated from the anus.
