Etymology: Oxycheilinus: Greek, oxys = sharp + Greek, cheilos = lip.
Environment / Climate / Range
Marine; reef-associated; depth range 2 - 110 m (Ref. 1602). Tropical; 32°N - 21°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 4392)
soft rays: 8. Body variable from brown to yellow or green mixed with various color shades or spots. Males develop long filaments on the caudal fin (Ref. 48636). Young with a broad, dark lateral stripe which breaks into dark blotches in adults, the largest above distal pectoral fins. A small dark spot behind eye. Mouth terminal or lower jaw slightly projecting. Caudal fin of terminal males rhomboid, with central rays longest, and dorsalmost caudal-fin ray elongated into a short filament. A small species (reaching about 14 cm) (Ref 9823).
Indo-Pacific: East Africa to the Hawaiian and Marquesan islands, north to southern Japan, south to Vanuatu.
Inhabits outer reef slopes or deep clear lagoons among rubble or clumps of algae; also in seagrass beds (Ref. 1602, 41878, 58302). Often in sheltered estuaries and harbors (Ref. 48636). Benthic and benthopelagic (Ref. 58302).

Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.01103 - 0.03003), b=2.77 (2.63 - 2.91), based on LWR estimates for species & Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.57 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (24 of 100) .
