Rosy Coffinfish, Chaunacops coloratus (Garman 1899)

More Info


Distribution

Off southern Queensland, depth 2500 m. Elsewhere the species is widespread in the Pacific Ocean: from the eastern Indian Ocean to the Marianas, Hawaii, and the eastern Pacific.
Inhabits highly rugose, rocky substrates on the Continental slope and rise.

Features

Dorsal fin 11; Anal fin 5-6; Pectoral fin 11-12; Vertebrae 19.
A species of Chaunacops with the following characteristics: buccal cavity not black, dusky in young becoming pale with age; tail moderately long, appressed anal-fin rays reaching or nearly reaching posterior end of hypural plate.

Remarks

Individuals are able to inflate their bodies, presumably to make themselves more globose and difficult to be preyed upon.

Similar Species

DNA sequences of tissue samples taken from the Australian specimen confirmed the identification as Chaunacops coloratus.

Etymology

The specific name is from the Latin coloratus (= colored). The species was described as being a “deep rose” colour in life, “tinted with blue to blackish around the angles of the mouth and on the orbit around the eye”.
