Identification

The genus Deania contains a second Australian species, the Longsnout Dogfish, Deania quadrispinosa. The most obvious difference between them is the shape of the first dorsal fin. In the Brier Shark it is long and low, but the first dorsal fin of the Longsnout Dogfish is higher and has a shorter base. The Brier Shark is normally light or dark grey to dark brown.

Size range

It grows to 1.13 m in length.

Distribution

The Brier Shark occurs in the eastern Atlantic and the eastern and western Pacific. In Australia it is recorded around the south of the continent, from northern New South Wales to south-western Western Australia and Tasmania.

The species feeds on fishes and crustaceans.

Life cycle

Pups are born at about 30 cm, and both males and females mature at about 70 cm.
