Taxonomy
The original description of the cloudy catshark was published in 1908 by Shigeho Tanaka in the Journal of the Faculty of Science, University of Tokyo. He gave it the specific epithet torazame, which is its Japanese name (虎鮫, literally "tiger shark"), and assigned it to the genus Catulus. The type specimen was a 45 cm (18 in) long adult male caught off Misaki, Kanagawa, Japan. Subsequent authors have synonymized Catulus with Scyliorhinus.
