Fish are Friends Not Food

Great White Sharks feed during the daytime, and have a special mechanism that allows them to sense movement of a fish. It has special sensors that pick up on the movement of its prey, also they have a keen sense of smell and eye sight. All these things determine if a shark is going to attack its prey, which it does by charging it from underneath delivering a fatal bite and either swim away letting it weaken or chomping it up right there. The sharks diet mainly consists of seals, sea lions, fish, other smaller sharks, and elephant seals. Also they will eat dolphins is they can defeat it.

Guts and Glory

The white sharks digestion system is similar to ours, accept here aren’t as nearly many organs. The food is torn and chewed up by the razor sharp teeth and is immediately swallowed. It travels through a short esophagus where it eventually goes into the stomach by the control of a sphincter. Once in the stomach, the rugae or folds in the lining expand, a shark can eat up to 10% of its body weight. The stomach has HCl which breaks down bones, and Mucus which protects the stomach lining from the HCl. Furthermore, the pancreas has a duct or tube that empty protein digesting enzymes which starts protein breakdown.

The White Shark has a ring valve intestine which the food enters once broken down by the stomach by another sphincter. This where all the food nutrients is absorbed. Then the food is expelled through the anus after  it is as absorbed as it can be.
