Japanese fishermen found a rare megamouth shark caught alive in fishing nets in the Pacific near Tokyo. It was 5-meter shark, spotted about one kilometer off the coast of Tateyama, Chiba Prefecture. The megamouth is a deep-water shark that inhabits the Pacific and Indian Oceans and is characterized by its large mouth. Professor Sho Tanaka of Tokai University said megamouth sharks have been spotted only about 100 times in the world and just 20 times in Japan.
