Southern Sawshark, Pristiophorus nudipinnis Günther 1870

More Info


Distribution

Newcastle, New South Wales, to the Great Australian Bight, Western Australia, and around Tasmania.

Features

Body long, slender; head flattened, with a relatively broad saw-like snout or rostrum and barbels inserted closer to mouth than to snout tip; nostrils oval, positioned halfway between barbels and corner of mouth; dorsal and pectoral fins entirely covered with denticles. Pale grey to greyish-brown above, pale below.

Size

Females attain a maximum total length/maximum total body mass of 124 cm TL/4.3 kg. The smaller males reach 110 cm and 2.2 kg. Ageing studies indicate that the species has a maximum life span of nine years. 

Feeding

Sawsharks use the sensory barbels on the rostrum to find their prey. They injure or stun small fishes and invertebrates by vigorously moving their snouts from side to side.

Biology

Reproductive mode: aplacental viviparous (ovoviviparous), with embryos feeding solely on yolk. Length at birth 25 cm TL.

Fisheries

Taken as bycatch in the Southern Shark Fishery, the South East Trawl Fishery, and the Great Australia Bight Trawl Fishery. The three-mile closure of all Victorian waters to shark fishing provides a large refuge for the species.
