Protogobiesox asymmetricus

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.^[2] It is found in association with sunken logs and its unusual lateral asymmetry may be an adaptation for this habitat.^[3] 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] though this was later expanded with two other genera.^[4]
