Tiger shark - Scyliorhinus torazame

Japanese: トラザメ(虎鮫) - トラザメ（英語表記）Scyliorhinus torazame

A marine fish of the family Scyllidae in the order Carcharhinidae. Its name comes from the cloud-like patterns on its body that resemble the stripes of a tiger. In English, sharks in this family are collectively called cat sharks, which also refer to the pattern. It is distributed throughout Japan, the Korean peninsula, and China, with its southern limit being the Philippines and its northern limit being Hokkaido. Meanwhile, the closely related long-tailed catshark, Halaerulus buergeri , is found in large numbers in the central and southern parts of Japan, especially in Kyushu. Catsharks are strongly coastal, living on the seafloor at depths of less than 100m. In addition to the patterns on their bodies, they are characterized by the presence of labial folds around their mouths.

メジロザメ目トラザメ科の海産魚。名は，体に雲状斑紋があり，トラの縞模様に似ることによる。英語では同科のサメを総称してcat sharkというが，やはり斑紋に基づいている。日本，朝鮮半島，中国に分布し，その南限はフィリピン，北限は北海道とされる。一方，近縁のナガサキトラザメHalaerulus buergeriは中部以南とくに九州に多い。トラザメは沿岸性が強く，水深100m以浅の海底で生活する。体の模様のほか，口のまわりに唇褶があることが特徴。
