More Info


Distribution

Endemic to southern Australia from off Cape Hawke, New South Wales, to southwest of Esperance, Western Australia, including around Tasmania, at depths  to 900 m (most abundant at 400–600 m) on the continental shelf and slope. 
Inhabits soft sediment areas.

Colour

Ocular-side brown with diffuse, circular or sometimes ring-shaped blotches, and many scale pockets with distinct black outlines. Blind-side scales with several to many reddish-brown pepper-dot melanophores, that are especially numerous on the scales overlying the proximal pterygiophores of the dorsal and anal fins.

Feeding

Feeds on bentbhic invertebrates.

Biology

The biology, ecology and life history of this species is unknown.

Fisheries

Taken as by-catch in deepwater trawl fisheries.

Remarks

In most earlier publications, this species was confused with the similar Azygopus flemingi, found in New Zealand waters (Munro 2012).
