Etymology: Labracinus: Greek, labrax, -akos = a fish, Dicentrarchus labrax (Ref. 45335); cyclophthalmus: Name from Greek 'kyklos' meaning circle and 'ophthalmos' for eye, referring to the dark curved marking around the midposterior rim of the orbit. More on authors: Müller & Troschel.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 20 m (Ref. 9710), usually 10 - 15 m (Ref. 27115). Tropical; 22°C - 26°C (Ref. 27115)
Western Pacific: widely distributed throughout the Indo-Malayan Archipelago, from southern Japan, south to the Northwest Shelf of Australia, and east to New Ireland, Papua New Guinea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 23.5 cm TL male/unsexed; (Ref. 90102)
soft rays: 14 - 15. Lower lip uninterrupted at symphysis. Vomerine teeth relatively large, arranged in a chevron. Caudal fin rounded; upper part with 5 - 6 procurrent rays and 9 principal rays. Lateral line with anterodorsal series of 43 - 62 (usually 48 - 62) tubed scales extending from gill opening, and a peduncular series of 12 - 14 (usually 18 - 22) tubed scales. Dorsal and anal fins with distinct scaly sheaths (Ref. 37748).
Found near shelter of coral or rock of shallow reefs (Ref. 9710), with moderate surge or currents, in spread-out groups of mixed sexes. Also in tidal pools, reef flats and reef slopes, often in relatively silty areas at depths ranging to 20 m (Ref. 81967). Moves about activity through the gutters and passages (Ref. 48635). Feeds on small fishes (Ref. 559). Frequently seen in the aquarium fish trade, and has been bred in captivity (Ref. 35416, 37748).
