The digestive system of a Blue Ringed Octopus is truly interesting. What is even more interesting is how the animal kills its prey. The Blue Ringed Octopus has two different techniques for killing its prey. Its first method is to pull its food apart with its suckers. Once the animal captivates its prey, it rips it apart with suckers to kill it. Its second technique is to either bite open the shel or drill into the shell of an animal. A picture of the powerful beak is shown to the left. After they do this, they inject a deadly neurotoxin that kills the animal and starts the breakdown of the animal. After the food is ready for eating, the food will go through the animals two way digestive system containing a mouth and an anus. After the food is swallowed, the food travels down it's esophagus which digests the food further with digestive glands. Then it goes to the crop. The crop works the same way that a liver or pancreas would on a human. It contains multiple digestive sacs that digest the food further than when it was in the digestive sacs in the esophagus. From here, it travels to the stomach where acids break down the food more fully with the help of enzymes. From the stomach, the food moves through to the caecum. The caecum is a vital because here, the food is filtered. The nutrients from the food are stored for future use and the pieces of food move onto the next stage, the intestines. in the intestines. These indigestible pieces are transported to the anus. In the anus, the food is finally excreted after its long journey through the Octopi's digestive system. A picture of the full digestive system can be seen towards the right of the page.
