Summary:

Widespread in southern Australia, and abundant on coastal reefs and weedy areas in Western Australia. The Brownspotted Wrasse changes sex from female to male during its life.

Juveniles and females:
•Variable in colour from pale greenish to reddish-brown
•Pale centres on some body scales  create a row of white spots along the lateral line
•Five obscure brownish bars on back between dorsal fin and lateral line
•Head and body spotted with darker brown markings; markings around eye in radiating pattern.

Males:
•Dark reddish-brown or deep chocolate-brown with a broken whitish band along side below lateral‑line
•Ventral surface whitish
•Body scales with gold, dark brown, or whitish centres, giving a marbled or spotted appearance.

More Info


Distribution

Endemic to southern Australia from Queenscliff, Victoria, to Shark Bay, Western Australia. Inhabits shallow rocky reefs to depths of 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

Meristic features
Dorsal fin spines/rays: IX, 11
Anal fin spines/rays: III, 10
Caudal fin rays: 12
Pectoral fin rays: 14
Pelvic fin spines/rays: I, 5
Lateral line: 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 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 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

Carnivore - 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 - changes sex from female to male at some stage in its life cycle. The species breeds during late winter to early spring. Spawning occurs in seagrass and reef habitats and 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

  • EPBC Act 1999 : Not listed
  • 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).
