Distribution


Endemic to southern Australia from Glenelg, South Australia, to Perth Western Australia. The species is common in shalow areas of the Great Australian Bight. Usually inhabits sandy areas near seagrass beds in shallow sheltered bays. 

Features

Disc subcircular, wider than long, anterior edge obtuse; snout fleshy, tip slightly extended; eyes of moderate size (20–27% preocular snout length); posterior margin of spiracles rounded; 7–9 minute papillae on mouth floor, immediately behind teeth; internasal flap skirt-shaped, posterior angle not extended into distinct lobe; tail of moderate length (71–91% disc length); no dorsal fin; caudal fin lanceolate.

Biology

Attains 17 years of age. Males mature at around 31-34 cm TL and 2 years of ag; females mature at around 5 years of age. Fecundity is low, with females giving birth to 1-2 pups/year; size at birth is ~17 cm TL.

Fisheries

Taken as incidental by-catch in the Great Australian Bight Trawl Sector of the Southern and Eastern Scalefish and Shark Fishery, and in the South Australian Prawn Fisheries and in scallop and prawn trawl fisheries off Perth and Mandurah, Western Australia.
