Protogobiesox asymmetricus, is a species of fish in the family Gobiesocidae endemic to the deep-water off the north coast of Papua New Guinea. This species is the only known member of its genus.[1] It is found in association with sunken logs and its unusual lateral symmetry may be an adaptation for this habitat.[2] This species was described by Ronald Fricke, Chen Jhen-Nien and Chen Wei-Jen from a type locality of northeast of Taviltae, Madang Province in Papua New Guinea and these authors placed it in its own subfamily the Protogobiesocinae.[3]
