Argyropelecus hemigymnus, the half-naked hatchetfish, short silver hatchetfishorspurred hatchetfish, is a deep-sea hatchetfish of the genus Argyropelecus found mesopelagically in the Atlantic, Indian, and Pacific Oceans as well as in the Mediterranean Sea.[1][2] It is a small species rarely exceeding 38 millimetres (1.5 in) standard length.[3] It feeds on zooplankton, particularly ostracods and copepods.[4][5] Sexual maturation occurs at length of about 22 mm, and adult males have more developed olfactory organs than females, i.e. the species is sexually dimorphic.[6]
