More Info


Distribution

Off Wooli, New South Wales, to the Great Australian Bight, southeastern Western Australia, including around Tasmania. Inhabits soft sediment areas on the upper continental slope.

Features

Dorsal fin X–XI + 16–17; Anal fin 16–17; Caudal fin 11; Pectoral fin 11 + 3; Pelvic fin I, 5; Lateral line scales 64–69.

Profile of snout slightly concave, hump developing in adults; interorbital slightly to moderately depressed;  no groove above and behind the eye except in juveniles; bony rostrum with a small but prominent spine at each corner, bordered by smaller spines in young; scales ctenoid, firmly attached, absent from chest and belly anteriorly; lateral line scales not enlarged but with distinct spines; caudal fin with concave margin; pectoral fins reaching well beyond anal-fin origin. 

Colour

Reddish above, white below with dark blotches on back; roof of mouth yellow posteriorly; 1st dorsal fin with black spot, spot suffused with red in large adults; 2nd dorsal and caudal fins with broad red bands; inner surface of pectoral fins green to reddish with blue margin and black spot near inner corner of outer edge.

Feeding

Etymology

The species is named for the butterfly genus Vanessa, presumably in reference to the large colourful pectoral fins that may resemble butterfly wings.
