The lettuce sea slug is a colorful species of sea slug recognizable by their resemblance to a nudibranch.
It is often green in color and has a frilly edge because of its parapodia. This makes the slug look just like the leaves of lettuce.
They live in the tropical parts of the western Atlantic Ocean, in places where the water is shallow and clear.
