More Info


Distribution

Sugarloaf Point, New South Wales, around southern Australia including Tasmania, to Cape Leeuwin, Western Australia. Elsewhere the species is widespread with a patchy distribution in the northern Atlantic and Southwest Pacific: New Caledonia, New Zealand and the North Atlantic.
Inhabits the continental slopes and seamounts.

Features

Vertebrae, monospondylous + precaudal diplospondylous vertebrae 36-43 + 26-32 
Snout moderately long, slender, length less than 4 times eye diameter and less than width, fleshy and tapering evenly anterior to nostrils; teeth medium-sized, widely spaced, lacking distinct ridges and with 3–5 cusps, central cusps much larger than adjacent cusps; denticles tricuspidate, closely spaced; dorsal fins similar in size; anal fin triangular, low and long, its height much less than its base length; pectoral fins small but longer than head width near mouth.

Biology

Mature males are >61.5 cm TL and females are >59.6 cm TL. Little is known of the biology of this species, and the reproductive mode is assumed to be oviparous.

Etymology

The specific name melanoasper is from the Greek melanos (= black, dark coloured) and the Latin asper (= rough), in reference to the black coloration and rough skin of this species.
