Green sea turtle
Green turtles are omnivorous when they are young, eating plants, algae, plankton and other small animals. As they get older, they become herbivorous, eating only plants such as sea grass. Their body fat is green from the chlorophyll of the plants they eat. The edges of their jaws have many points, like the edge of a saw. Their jaws can rip off pieces of plants and the turtles swallows the pieces whole.
