Summary:

Like many damselfishes, the White-ear changes colour with growth. The brightly coloured orange juveniles have neon-blue lines and spots on the head and upper body, a black ocellus ringed with neon-blue on the dorsal fin, and a white patch on the gill cover.

With growth, the body becomes brownish, and the neon blue markings and ocellus gradually disappear. Large individuals are yellowish-brown to black, with a distinct white "ear-like" marking on the gill cover that is visible at all growth stages.

White-ear, Parma microlepis Günther 1862

More Info


Distribution

Northern New South Wales to southeastern Tasmania and west to Anglesea, Victoria, at depths to 30 m. The White Ear is one of the most abundant rocky reef fishes in the Sydney region, but is very rare in Port Phillip Bay.

Common inhabitant of coastal reefs in New South Wales. Small juveniles often shelter among macroalgae in tide pools.

Features

Dorsal fin XIII, 16-18; Anal fin II, 14-16; Caudal fin 15; Pectoral fin 20-21; Pelvic fin I, 5; Lateral line scales 23-28; Gill rakers 19-23.

Body deep, somewhat oval, with a rounded head, a small terminal mouth, and a single long-based dorsal fin. Scales large, bases of dorsal and anal fins with scaly sheath of smaller scales. Colour highly variable from juvenile to adult.

Size

To 20 cm.

Colour

Large individuals are yellowish-brown to black with a distinct white "ear-like" marking on the gill cover. Small juveniles are bright orange with neon-blue lines, spots and a black ocellus ringed with neon-blue on dorsal fin.

With growth, the body becomes brown and the blue colour and ocellus gradually disappear. The white "ear" marking is visible at all stages.

Feeding

Omnivores

Biology

During the breeding season, individuals form breeding pairs. Males prepare 'nests' on rocky substrates by removing algae, detritus and encrusting organisms.

Females lay their adherent eggs onto this 'nest' site, and her male partner aerates and aggressively protects the eggs from all-comers, including divers who stray to close. The larvae are pelagic.

Studies have shown that P. microlepis grows rapidly durng the first 8 years of life, and can live to at least 37 years, and can reproduce for more than 30 years.

Fisheries

Of no interest to fisheries.

Remarks

The White ear is abundant on coastal reefs along much of the New South Wales coast. Divers are very familiar with these small territorial fishes, especially during the breeding season when males aggressively guard their eggs against predators.

Similar Species

Differs from the similar Parma victoriae in having a white patch on the gill cover at all stages throughout the life cycle.

Etymology

The specific name microlepis is from the Greek mikros (= small) and lepis (= scale), possibly in reference to the small scales of this species compared with related species.
