More Info


Distribution

Black Rock Entrance to the Swain Reefs area, Great Barrier Reef, Queensland. Elsewhere, the species occurs in Palau, the Marshall Islands and Fiji in depths of 15-40 m.

Specimens from the Marshall Islands were found on Halimeda beds in depths of 15–27 metres, and one collection included algae of the genera Padina, Caulerpa, and Dictyota. Specimens from Queensland were trawled in 25-50 m.

Features

Dorsal fin IX spines as VII(I)-I, 9 (rarely VII-I, 8); Anal fin II, 8; Pectoral fin 12; Pelvic fin I, 5; Caudal rays (principal) 1+8+7+1; Gill rakers (including rudiments) 12-14; Lateral line 21–22 (as 3–7 pored scales and 14–18 pitted scales); Vertebrae 10+14.

Size

Maximum length 29 mm SL.

Colour

Pale yellowish-brown with a reddish overlay on the head and lower body, and many white spots with red margins; spots smaller on head than on body; three or more whitish basicaudal spots; second dorsal, anal and caudal fins pale reddish with small white spots and translucent membranes (Fraser & Randall 2011).

Feeding

Feeds in small crustaceans.

Biology

Cardinalfishes are oral egg brooders. The sexes are separate and fertilisation is external. Following spawning, males take the egg mass into their mouths and brood the developing eggs until the larvae hatch.

Fisheries

Of no interest to fisheries.

Conservation

IUCN Red List of Threatened Species: Not Evaluated

EPBC Act (Australia): Not listed

Etymology

The specific name nivosa is from the Latin nivosus, meaning 'snowy', in reference to the numerous whitish spots on the body.
