More Info
Distribution |
Endemic to Western Australia, from the Recherche Archipelago to Kalbarri. The species is abundant on inshore rocky reefs along the south-west coast. |
Features |
Dorsal fin XIII, 18-19; Anal fin II, 14-15; Pectoral fin 20-21; Pelvic fin I, 5; Caudal fin 15; Gill rakers 19-23; Lateral-line scales 27-32. Body deep (52-59% SL), compressed. Head of moderate size (29-33% SL); eyes small (23-31% HL); mouth small, oblique; each jaw with single row of elongate, narrow teeth having conical to nearly pointed tips. Scales ctenoid, large, covering body, most of head and fin bases, membranes of vertical fins mostly covered with small scales; lateral line interrupted, anterior segment following contour of back to below first few soft dorsal fin rays, posterior segment originating immediately below on midline of side, continuing to base of caudal fin. Dorsal fin continuous, with elongate base, spines of similar length, soft portion much taller than spinous portion, somewhat triangular in profile; anal fin opposite and similar, though somewhat lower and more lobe like than posterior half of dorsal fin; caudal fin forked, tips pointed. Pectoral and pelvic fins pointed, of moderate size, pelvics thoracic. |
Colour |
Adults dark brown to nearly black with blue spots scattered over body; anterior margins of fins with neon blue edge. Juveniles mostly yellow; head and back darker with blue spots and lines. |
Feeding |
It consumes algae (Saunders et al. 2013, 2014). |
Biology |
Males construct and maintain nests of red and green algae during late spring and early summer,. Females lay adhesive eggs into the nests, and the male parent guards and aerates the eggs until the larvae hatch. |
Fisheries |
Reportedly sold in the aquarium trade. |
Etymology |
The species is "named in honour of the late ichthyologist A. R. McCulloch, who drew, whilst still in his teens, the accurate and beautiful figures of the allied Parma microlepis showing its variations with growth”. |
