Summary:

Adult males are dark reddish-brown to dark chocolate-brown with a broad broken pale band along the side below the lateral-line, a whitish underside, gold, dark brown, or pale scales centres giving a marbled or spotted appearance, and a dark bar on the upper side of the pectoral-fin base. 

Females and juveniles are pale brownish to greenish, with pale centres on some body scales, usually five obscure brownish bars along the back above the lateral line, an indistinct zig-zag brownish band along the lateral-line joining the upper bars to lower bars, darker brown spots and markings on the head, and radiating lines around the eye.

More Info


Distribution

Endemic to southern Australia from Port Phillip, Victoria, to Dirk Hartog Island, Western Australia. Inhabits shallow algal-covered rocky reefs at depths to 20 m.

Although widespread in southern Australia, this species is common only in Western Australia where juveniles and females are abundant on algal covered rocky reefs. It is also common in seagrass beds on the west coast.

Features

Dorsal fin IX, 11; Anal fin III, 10; Caudal fin 12; Pectoral fin 14; Pelvic fin I, 5; Lateral line scales 25-26.

Body moderately deep (30‑38% SL), compressed; head moderately large (30‑35% SL), dorsal profile convex; eyes moderately large (14‑25% HL); mouth small, upper jaw not reaching as far as eye; teeth moderately large, caniniform, anterior two pairs in both jaws enlarged and recurved; upper jaw lacking enlarged canines at rear. 

Scales moderately large, cycloid, firmly attached, covering body; no scaly sheath at base of dorsal and anal fin; head naked except for one or two rows of cheek scales and 15‑16 large scales on opercle; lateral line abruptly curved downwards below soft dorsal fin. 

Dorsal fin continuous, with elongate base and uniform height; anal fin similar to rear half of dorsal fin; caudal fin truncate. Pectoral fins moderately large, upper rays longest, not quite reaching to anus. Pelvic fins short, arising beneath pectoral-fin bases, not reaching near anus.

Colour

Juveniles and females (Initial Phase) are pale brownish to greenish, with paler centres on some body scales; five obscure brownish bars on back between dorsal fin and lateral line in the interspaces between the upper bars; indistinct zig-zag brownish band joining upper and lower bars along lateral‑line; head and body spotted with darker brown markings; markings around eye in radiating pattern; dorsal and anal fins dusky brown with darker markings; caudal and pectoral fins translucent yellowish. The base colour of smaller individuals is highly variable.

Adult males (Terminal Phase) are dark reddish‑brown or deep chocolate brown with broken whitish band along body beneath lateral‑line; ventral surface whitish; body scales with gold, dark brown, or whitish centres, giving marbled or spotted appearance; fins dusky or reddish brown; dark bar on upper side of pectoral-fin base.

Feeding

Feeds on a range of benthic invertebrates on sandy bottoms, and amongst seagrass and macrophytic algae. Prey items include gastropod molluscs, a range of crustaceans (including amphipods, isopods, prawns and crabs) and echinoids.

Biology

The Brownspotted Wrasse is a protogynous hermaphrodite - changing sex from female to male during the life cycle. 

The species breeds in late winter to early spring, and spawning occurs in seagrass and reef habitats. The eggs and larvae are pelagic.

Fisheries

Although not targeted, Brownspotted Wrasse are taken as bycatch in the rock lobster and giant crab fishery (South Australia), and possibly in the West Coast Demersal Scalefish Fishery (Western Australia).

Also taken by recreational anglers in Western Australia, however, the flesh is not considered to be of high quality (Pollard et al. 2012).

Conservation

  • IUCN Red List : Least Concern
  • Etymology

    The specific name parilus from the aboriginal word 'Paril' - the name given this species by the indigenous people of King George Sound (Richardson, 1850).
