Digestive system of the Atlantic Pygmy Octopus (Octopus Joubini)
The Atlantic Pygmy octopus mainly eats small crustaceans. Two ways that the Octopuses have of getting the meat out of sea creatures such as lobsters and shrimp are that they will bite/drill the shell with their beak or they will use the great strength and suckers that they have. with their salivary glands they secret digestive enzymes onto the organism. At the same time they are injecting paralyzing poison to help immobilize their victim. They have very sharp teeth that they use to tear up their preys tissue. After their saliva breaks down the shredded tissue, it goes down the esophagus which has more digestive glands. After it goes through the esophagus, the Crop organ widens and holds the partially digested food. They do this so that their food could get more digested because they do not have a liver/pancreas. After it goes through the crop, the food goes through the stomach and the Caecum. In this stage the food gets churned in the stomach because he stomach acts as a muscular organ. After it is churned by the stomach the food goes to the Caecum where the nutrients are absorbed from the food and everything not absorbable goes to the intestine and anus. The bone and shells left at the end of digestion are put through the anus. Octopus eggs and ink also come out of this hole.
