The suction cup formed by the first dorsal fin on the back of the fish head is longer and has 22 to 26 pairs of cartilage plates in horizontal rows. The second dorsal node is as long as the anal fin base and has 35 to 40 fin rays. The caudal fin is pointed in juvenile fish and gradually becomes concave fork-shaped in adult fish.
The general body length is 220 to 450 mm, with a maximum length of no more than 900 mm. Although its swimming ability is poor, it is distributed in all sea areas of the world. It mainly relies on the suction cup with strong adsorption force on its head to adsorb to the ventral surface of the body of large sharks or sea animals with strong swimming ability. Sometimes it is also adsorbed to the bottom of boats. It does not Required to swim and be carried to the world's oceans. When it reaches a sea area with abundant food, it breaks away from the host and ingests food. Then it is adsorbed to a new host and continues to move to other sea areas.
Widely distributed in tropical, subtropical and temperate seas around the world. It is produced all along the coast of our country.
