Taxonomy

Pogonophryne was first described as a genus in 1914 by the English ichthyologist Charles Tate Regan when he described a new species of fish, Pogonophryne scotti, which had been collected on the Terra Nova Expedition in the Ross Sea. P. scotti is, therefore, the type species of Pogonophryne by monotypy.[1][2] The genus name is a compound of pogonos meaning "beard", a reference to the barbel on the chin of P. scotti, and "phryne" which means "toad", possibly an allusion to the bumps and knobs on the head, like the skin of a toad.[3]

Characteristics

Pogonophryne plunderfishes have a broad head which is flattened with post-temporal ridges which vary from weakly to well developed. They have a snout which is longer than the diameter of the eye and a broad space between the eyes. The mental barbel, the barbel on the chin which characterises the barbeled plunderfishes, is tapered to a point or expanded at its tip to a varying extent and frequently has branched or simple processes. The pper lateral line has tubular scales at the front and disc-shaped scales towards the back. The middle lateral line normally has disc¬shaped scales to the front and tubular scales to the rear, frequently these are interspersed with disc-shaped scales.[13] The maximum length of these fishes varies from a standard length of 3.8 cm (1.5 in) in P. albipinna to a total length of 35.5 cm (14.0 in) in P. neyelovi.[4]

Distribution, habitat and biology

Pogonophryne plunderfishes are found in the Southern Ocean around Antarctica reaching as far north as the South Shetland Islands.[13] They are bathydemersal or bathypelagic[4] in deeper water typically at depths greater than 100 m (330 ft). Their biology is little known but they are known to feed on polychaetes and crustaceans such as mysids, isopods and copepods.[13]
