The Japanese Hairy Fish is a mystery fish of Japan. It is said to have a scaly, fish-like body, with a length of 4–5 feet, with human-like hair on the head. Aggressive. Emerges from the water to fight or play. Emits loud cries. Said to attack and kill humans by disemboweling them. It is said to live in an unspecified river in Japan. It could possibly be a distorted account of the Northern fur seal (Callorhinus ursinus), suggested by David Heppell. It is about the right size, has finlike flippers, barks like a dog, and can be very playful. The Kuril Islands serve as a breeding grounds from May to June; little is known of the animal’s whereabouts out side the breeding season.
