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]
