The shortspine spurdog (Squalus mitsukurii) is a dogfish, a member of the family Squalidae, found on continental shelves off Japan in temperate waters, from the surface to 950 m. Its length is up to 75 cm.[2]
Taxonomy
The shortspine dogfish was once seen as a circumglobal species by many authors, including Compagno (1984) and Last & Stevens (1994).[3][4] However, a series on papers published since 2007 have shown that a number of species synonymized with S. mitsukurii are distinct, and that the Hawaiian population of S. mitsukurii represent a distinct species, the Hawaiian spurdog.[5][6][7]
