Callionymus izuensis

Callionymus izuensis, the Izu dragonet, is a species of dragonet which is endemic to the waters around the Izu Islands of Japan. It is found at depths of 16-18 m over substrates consisting of coarse sand, although sometimes coral rubble and broken shells may form part of the habitat. It was originally described as a subspecies of Callionymus persicus from the western Indian Ocean and has also been placed in the genus Calliurichthys by some authorities.
