The sea rabbit belongs to Cephalopoda, squid family, and its trunk length can reach up to 15 cm, which is similar to that of squid, but shorter and wider than squid.

Sea rabbits are small in size, the longest of which is no more than15cm. Their bodies are symmetrical from left to right, and the length of their trunks is four times the width of their trunks. The orbits on both sides of the head are large, and there are pseudocorneas on the outside of the eyes, which communicate with the outside world only through small tear holes. There are 10 wrists in front of the head and around the mouth, of which 4 pairs are short, with two rows of suction cups on the wrists, and the other 1 pair is long, which is the wrist touching ear, with four rows of suction cups on the ear.
