Introduction

The Rough Leatherjacket is a secretive fish, living amongst dense seagrass and kelp covered rocky reefs.

Identification

The Rough Leatherjacket has a compressed body, an acutely pointed snout and a small mouth. It is covered with coarse scales that make the skin very rough to touch.

The colour of this species is variable from brown to greenish, grey or white. It usually has a dark blotch above the pectoral fin, three lines across the forehead and two dark bars on the "corners" of the caudal fin. There are usually other brown and blue markings. Juveniles often have a series of dark blotches along the side of the body.

S. granulatus is the only species in the genus Scobinichthys.

Distribution

The Rough Leatherjacket occurs in shallow temperate marine waters from southern Queensland, around the south of the country and north to the central coast of Western Australia.
