Argyropelecus hemigymnus, the half-naked hatchetfish, short silver hatchetfish or spurred hatchetfish, is a deep-sea hatchetfish of the genus Argyropelecus found in mesopelagically in all oceans. It is a small species rarely exceeding 38 millimetres (1.5 in) standard length.[1] It feeds on zooplankton, particularly ostracods and copepods.[2][3] 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.[4]
