trait
Zombie fish looks a bit like a fish-like eel, with tall eel-like skin and no scales. They have a long dorsal fin on their backs, which extends backward to the tail and forms a caudal fin around the tail. In addition, they have no other fins on their bodies, but two dorsal fins.
Their mouths are full of funnels. Zombie fish without whiskers have only one nostril between their eyes. Their eyes are rich and sensitive. There are seven gill holes on both sides of their bodies behind their eyes, hence the name lamprey. There are two semicircular canals in the inner ear, and the end of the nasopituitary capsule is the blind capsule.
