More Info


Endemic to north Western Australia from off Rowley Shoals to Ashmore Reef, on the outer continental shelf and upper slope in depths of 150-455m.


Almost nothing is known of the biology, habitat and ecology of this species.


The specific name speccum is from the Latin specca meaning 'speckled', in reference to the speckling of dark brown spots and blotches in this species.
