Etymology: Cheilodipterus: Greek, cheilos = lip + Greek, di = two + Greek, pteryx = fin (Ref. 45335). More on authors: Smith & Radcliffe.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 25 m (Ref. 90102). Tropical; 15°N - 3°S
Western Pacific: Philippines, Malaysia, and the Solomon Islands. Occurrence in Indonesia, Papua New Guinea and the Great Barrier Reef (Ref. 9710) needs confirmation.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm TL male/unsexed; (Ref. 9710)
Morphology | Morphometrics
soft rays: 8. Body with midlateral black stripe, as wide as the pupil, tapers to a point on base of middle caudal-fin rays; body and head below it generally yellow; on snout and behind pectoral fin, midlateral stripe is bordered by a narrow yellowish white zone; above mid-lateral stripe body and head white, but top of head with a yellow tinge; dorsal stripe dark gray, separated from dorsal fins by a narrow white zone; a median dark gray stripe may be present from interorbital area to first dorsal-fin origin; fins pale. Developed gill rakers on hypobranchial 0-1; on ceratobranchial 8 (Ref. 8525).
Inhabits protected habitats, where conditions are similar to those of lagoons. Also found on coastal reefs (Ref. 9710). Usually seen solitary, occasionally in pairs. Mimics the sabre-toothed blenny Meiacanthus vittatus. Active during day (Ref 90102).
