Rostrum long, narrow, and narrowly tapering, length of preoral snout 27 to 29% of total length. Bases of rostral barbels about 1.2 to 1.3 times closer to rostral tip than mouth; distance from rostral barbels to nostrils slightly less or equal to distance from nostrils to first to fourth gill slits. About 9 or 10 large rostral teeth on each side of rostrum in front of rostral barbels, 9 behind them. Distance from mouth to nostrils 1.3 to 1.4 times internarial space. Tooth rows 39 to 49 in upper jaw. Dorsal and pectoral fins covered with denticles in large specimens. Lateral trunk denticles largely unicuspidate.

Brief Summary
provided by FAO species catalogs
A common temperate-subtropical sawshark of the continental shelf and upper slope of Australia, found near or on the bottom,from close inshore to at least 311 m depth. Occurs in bays and estuaries, but more abundant offshore at about 37 to 146 m on sandy or gravel-sand bottoms. Apparently occurs in schools or aggregates, possibly for feeding. Ovoviviparous, said to "breed in the winter month" (Whitley, 1940). Eats small fishes, including coronet fishes (Fistularia), and crustaceans.

Benefits

This abundant small shark has formed the basis for a considerable bottom trawl fishery off southern Australia. Utilized fresh for human consumption. Apparently the meat of this shark is excellent eating.
