Eel prey on fish and small crustaceans. Some eel have mouths consisting of a sucker surrounded with small teeth. The teeth pierce the scales and skin of fish and the eel sucks the blood for nourishment. Other species of eel have many sharp teeth and are able to bite and tear their prey into pieces to eat.
Food Preferences And Resources. Depending on the species, sea turtles may be carnivorous (meat eating), herbivorous (plant eating), or omnivorous (eating both meat and plants). The jaw structure of many species is adapted for their diet. Green sea turtles have finely serrated jaws adapted for a vegetarian diet of sea grasses and algae. As adults, these are the only herbivorous sea turtles. Some species change eating habits as they age.
