Jaw
Sea turtles do not have teeth but their mouths are sharp and beak-like for crushing and tearing food. Depending on the species, sea turtles may be carnivorous, herbivorous, or omnivorous. Their jaws are adapted for their diet. A loggerhead's diet consists primarily of crabs, mollusks, shrimps, jellyfish, so their jaws are adapted for crushing and grinding. Whereas, green sea turtles, the only adult herbivorous sea turtles have finely serrated jaws adapted for a vegetarian diet of sea grasses and algae.
