Older tiger sharks, can and do, eat turtles Green sea turtles can comprise 7% to 27% of a older tiger's diet, depending on region. If the shark is large (or the turtle small) they will swallow the animal whole. If the turtle is larger, a tiger shark has the dentition to bite through the shell.

To rid their bodies of a shell, which takes a very long time to dissolve in their very strong stomach acids, tiger sharks use gastric eversion. Sharks who do this relax their stomach muscles and use abdominal pressure to prolapse and speedy retraction of the stomach to empty indigestible particles, parasites, or mucus, researchers speculate. This may also aid them in keeping a healthy alimentary tract.
