Dusky Sharks have a distinct ridge running between the 2 dorsal fins on their back towards their tail. This ridge can also have small wavy lines running away from it.

Some Dusky Sharks have a slimy coating covering the upper side of their body. They grow slowly and range in size up to 3.5 m, living for up to 55 years. Dusky Sharks feed on:

• a wide variety of invertebrates

• marine mammals.

Habitat

Dusky Sharks live in the continental shelf and gulf waters of South Australia. They are sometimes caught in the same water as Bronze Whaler Sharks.

While mostly found in tropical and sub-tropical waters, they are highly migratory.

Large juveniles move to temperate waters between South Australia and Western Australia during the warmer periods of late spring, summer, and early autumn.
