More Info


Distribution

Endemic to eastern Australia, from off Rockingham Bay (Queensland) to off Tathra (New South Wales), and possibly on the Britannia Seamount off Queensland and New South Wales. Found on the outer continental shelf and upper slope in depths of 114–606 m.

Biology

A poorly known species, with very little known of its habitat and ecology. Swell sharks are egg layers (oviparous). Male Northern Draughtboard Swellsharks mature at 55–60 cm TL and the smallest free-swimming individual known measured 17 cm TL.

Fisheries

Although not targeted, the Northern Draughtboard Swellshark is taken as bycatch in commercial prawn and trawl fisheries in southern Queensland and New South Wales.

Etymology

The specific name variegatum is from the Latin variegatus meaning 'various', in references to the strong intraspecific and ontogenetic variability in colour pattern and morphology among the specimens examined.
