Distribution

Endemic to eastern and southern Australia with a disjunct distribution from Byron Bay to Montague Island, New South Wales, and at Wilsons Promontory and in Port Phillip, Victoria, and from Victor Harbor, South Australia, to Rottnest Island, Western Australia.
Inhabits sandy or muddy areas in the vicinity of reefs or other structures, preferring sheltered waters in protected bays, estuaries or deeper offshore reefs. Individuals swim by gliding above the seafloor, regularly perching on their pelvic fins to survey the surroundings.

Features

Dorsal fin IV, 24-25; Anal fin 20; Caudal fin 15; Pectoral fin 16-17; Pelvic fin I, 5; Lateral line scales 65- 67.
Body elongate, shallow (15-17% SL), very little compressed; caudal peduncle of moderate depth. Head moderately small (27-29% SL), slightly depressed, moderately pointed; eyes large (22-27% HL), positioned dorsolaterally; interorbit narrow; mouth large, reaching below front edge of eyes; teeth pointed, broad band of small teeth at front of each jaw bordered by two rows of longer curved canines, one at front of jaw and one along each side; spine high on free margin of opercle; numerous fine pores evenly spread over head. 
Scales ctenoid, moderately small, covering body but absent from head; lateral line continuous, gradually descending to lateral midline on caudal peduncle. 
Dorsal fin continuous, with elongate base, short spinous section noticeably lower than, but broadly joined by membrane to soft portion, spines of similar length, soft portion of uniform height; anal fin with elongate base, slightly shorter and lower than soft portion of dorsal fin; caudal fin small, slightly rounded. Pectoral and pelvic fins of similar length, with middle rays longest, pelvic fins based below and slightly in advance of pectoral fin bases.

Colour

Pale greyish to brown above, whitish below, with large black spots in horizontal series low on sides; dark line or series of close set spots extending from gill opening to upper side of caudal peduncle; small dark spots on upper surface of body and large black spots on head; large black spot on upper side of caudal fin base; dorsal fin pale with dark area on spinous portion; anal fin bluish white with dark margin; caudal fin bluish white with broad dark margin and dark area along base; pectoral fin white basally, transparent distally; ventral fin white.  Juveniles with yellow or orange, rather than black spots low on sides and white-edged black ocellus on caudal fin base.

Feeding

This "sit-and-wait" ambush predator is usually well-camouflaged on shelly bottoms.
