The pen-pipe fish has a peculiar shape. It is a slender cuttlefish, sometimes written as a pipe fish. Some people in Dalian, Qingdao and other places also call it sea rabbit. The squid is also called the Japanese squid, also known as the squid, small squid, and black octopus. From the appearance, it is a kind of cuttlefish with a slender body.

The pen-tube fish belongs to the class Cephalopod and belongs to the family Squididae. Its carcass length can reach up to 15 centimeters. Its shape is similar to that of a squid, but it is shorter and smaller than the squid, and its body is shorter and wider. Some people from Dalian and Qingdao also call it "Sea Hare". Because this kind of pen-tube fish escapes quickly, it can be said to be as quiet as a virgin and as active as a stray rabbit.
