Acanthodraco
Acanthodraco is a monotypic genus of marine ray-finned fish belonging to the family Bathydraconidae, the Antarctic dragonfishes, its only species is DeWitt’s dragonfish ("Acanthodraco dewitti"). They are found in the Southern Ocean and the southeastern Pacific Ocean. "Acanthodraco" was first formally described as a genus by the Polish ichthyologist in 1995 when he was describing its only species "Acanthodraco dewitti". The type locality of "A. dewitti" is the South Shetland Islands. The genus name is a compound of "acanthus", which means “thorn” or “spine” alluding to the higher number spines on the operculum than related genera, and  draco Meaning “dragon”, a common suffix in the scientific names of notothenioid fishes. The specific name honours the American ichthyologist Hugh Hamilton DeWitt, a renowned worker on notothenioid fishes. "Acanthodraco" is a bathydemersal fish found at depths of at least and since the original description has been found in the Ross Sea and in the southeastern Pacific Ocean off Chile. "A. dewitti" probably has a Circumpolar distribution around the Antarctic and is replaced in the seas around South Georgia by the similar "Psilodraco breviceps". Two specimens from the Ross Sea had standard lengths of and respectively. The had 27 rays  in the dorsal fin and 25-26 rays in the anal fin. These specimens were of either sex and their gonads were developing towards spawning. This alongside the presence of postlarvae in Terra Nova Bay suggest this species spawns in the Ross Sea.
