The sea hare is not a rabbit. The sea hare raised two ears (actually tentacles) and looked like a rabbit, with its head one behind the other, but without hair. It has two pairs of tentacles and long posterior tentacles. When it is not moving, it resembles a little white rabbit crouching on the ground with a pair of big ears erected, so it was first called a sea hare by the Romans. Later recognized by the world, the sea hare got its name. The sea hare is a marine snail mollusk that lives in corals. It has a thin, transparent shell on its back. It is generally white and has the reputation of “submarine gems”. It feeds on sea anemones, sponges, and polyps.
