The Atlantic Green Sea Turtle can work with other fishes to keep its hygiene good. The animal the the green sea turtle works with is the Yellow Tang. The Yellow Tang likes to eat algae from the shell of a green sea turtle, because it contains a lot of algae. A green sea turtle can just swim near the shore and the yellow tangs will be ready to feast off the shell. The yellow tang benefits from this by getting a meal and not having to forage where there are predators are out to eat them. The green sea turtle benefits also because their shells are cleaned so their hygiene is better, and they'll be able to move throughout the water quicker without friction against the water from the algae.
