Gymnodraco acuticeps

Gymnodraco acuticeps, commonly known as the Plough Fish or Antarctic Dragonfish, is a benthic fish native to the Southern Ocean, particularly around the Antarctic Peninsula. Belonging to the family Nototheniidae, it is highly adapted to survive in the extreme cold of its habitat, typically found at depths ranging from 0 to 550 meters, though it is rarely observed below 50 meters. The name Gymnodraco is derived from the Greek words gymnos (meaning “bare” or “naked”) and draco (meaning “dragon”), which fittingly describe its dragon-like appearance and lack of scales. Its specific epithet, acuticeps, refers to its sharply pointed head, a distinctive feature that aids in identifying the species. This fish exhibits several remarkable adaptations, including antifreeze glycoproteins in its blood that prevent ice crystal formation, allowing it to thrive in subzero waters. As a benthic predator, it feeds on small invertebrates and plays a key role in maintaining the balance of the Antarctic benthic food web.

==Taxonomy== The ploughfish was first formally described in 1902 by the Belgian-born British ichthyologist George Albert Boulenger with the type locality given as Cape Adare in Antarctica, Boulenger placed this species in a new monotypic genus Gymnodraco, it is still the only known species in that genus. The genus name is a compound of gymnos which means "bare" or "naked", a reference to the almost complete lack of scales on the body, and draco meaning "dragon" and is a common suffix used for notothenioid fish names. The specific name acuticeps means "pointed head" an allusion to the strongly depressed head with its sharply pointed snout.
