More Info


Distribution

Point Quobba to North West Cape, and offshore reefs of north Western Australia, Ashmore Reef in the Timor Sea, and the far northern Great Barrier Reef, Queensland, and reefs in the Coral Sea, to Cook Island, northern New South Wales. Elsewhere the species occurs in the tropical western-central Pacific.
Found on coral and rocky reefs, with pairs inhabiting tide pools, reef flats, lagoonal patch reefs and reef slopes, most commonly in areas with strong currents and surge. This secretive species shelters in holes and crevices.

Features

Dorsal fin III,21-23 (anterior spine tiny); Anal fin III,12-14: Pectoral fin 17-19; Pelvic fin I,5; Gill rakers 3-5 + 10-11 = 13-16; Lateral line (disjunct) 24-31 anterodorsal series) + 6-11 (peduncular series); Circumpeduncular scales 16; Vertebrae 10+16.
Body relatively slender; distance from dorsal-fin origin to pelvic-fin origin 25-28% SL. Lower lip either uninterrupted at symphysis, or with weak interruption only. Vomerine teeth relatively large, arranged in a chevron. 
Dorsal and anal fins without distinct scaly sheath; caudal fin rounded; 

Feeding

Feeds on small crustaceans, including crabs, isopods, and copepods.

Biology

Dottybacks are protogynous hermaphrodites, and capable of bi-directional sex change. The form small harems with a dominant male and several females.

Etymology

The specific name cyanotaenia is from the Greek kyanos (= light blue) and the Latin  taenia (= ribbon, band), in reference to the pale blue bars on the sides of males.
