The green sea turtle, also known as the green, black, or Pacific green turtle, is one of the largest species of sea turtles and has a wide population distribution throughout the world’s tropical and subtropical seas. There are two distinct populations in the Pacific and Atlantic Oceans, but they can be found throughout the Indian Ocean as well. They are unique in that they are the only species that are strict herbivores as adults, feeding mostly on algae, seagrass, and seaweed.
