Digestion

The squid has a flow through digestive system. The food enters the digestive tract through the squid's mouth and is digested into feces and monomers in the squid's stomach. The feces exit the body through the anus and the monomers are transported by the blood and absorbed by the tissues.Their normal diet is sperm whales. Oddly enough sperm whales also eat them.

Squids are preys and predators. Squids eat shrimp (crustaceans), fish, and other squid because they are carnivores (meat-eaters). Although squid eat a variety of creatures, they get preyed by a variety of animals like sharks, other fish, whales, squid, and people.

They catch the prey with their tentacles, hold on to the food, bite on it, and consume. The suckers on the arms are used for getting the prey, and bringing it to the beak (mandible). The digestion occurs in the brain, but before that it undergoes through the radula(a row of teeth)for further digestion. Talking about headaches.

A sharp, horny beak cuts up food into bite-sized chunks. The giant squid's beak is 1 1/2 times the size of this one from Mesonychoteuthis hamiltoni, a large squid that lives in waters around Antarctica. 3/4 view drawing of squid with open beak and radula sticking out A file-like radula rams food down the throat and esophagus, which passes directly through the brain to the stomach.
