Description
Dorsal spines (total): 9; Dorsal soft rays (total): 10-11; Anal spines: 3; Anal soft rays: 8-9; Pectoral fins with 2 unbranched and 10 branched rays; Pectoral fin rays: 11-12 (2 uppermost rays unbranched); Pelvic fin rays: I, 5, short, not reaching to anus; Caudal fin rays 13–14 (upper and lower 2 rays unbranched), truncate to double emarginate, with corners produced into short pointed lobes. Pored lateral line scales: 22 (13 on anterior lateral line, 9 on posterior lateral line); Vertical scale rows: 2 + 7; Number of scales on black streak: 19; Pored scales on black streak: 8; Predorsal scales: 6; Gill rakers: 5 + 6 = 11; Branchiostegal rays: 5; Vertebrae: 10 + 12 = 22. Scaly sheath extending onto dorsal and anal fins; Cheek scales reaching just anterior to forward extent of orbit, broad naked margins adjacent to orbit and free preopercular edge; Subopercular scales extending anteriorly to vertical at centre of eye. Body moderately slender, its depth: 2.8-3.0 in SL. Head pointed, dorsal profile nearly straight with slight concave inflexion above eye in juveniles and small adults, concave in front of eye in large adults; Lower jaw prominent, 2 strong canines situated anteriorly in each jaw; No enlarged tooth present on rear of upper jaw; Corner of mouth extends rearward to vertical at forward extent of orbit. Posterior ends of dorsal and anal fins bluntly pointed to rounded. Max. length: 21.0 cm TL. Depth range: 25 - 60 m.
Color
Body light red dorsally, becoming white ventrally with ventral scales flecked with red; A dark midlateral stripe on body; Head and dorsal part of body finely flecked with small orange-red and some brown dots, the nape and upper body flecked with tiny white dots; Dorsal and anal fins translucent whitish, mottled with light red and marked with irregular whie lines and dots, the dorsal fin with a black spot anteriorly; Caudal fin with pinkish white lobes spotted with light red, the central region of fin greenish, shading to yellowish posteriorly, the caudal-fin rays deep blue-green; Pectoral fins pale; Pelvic fins white with a broad light red band near base.
Etymology
Oxycheilinus: from Greek, oxys = sharp + from Greek, cheilos = lip.
arenatus: from Latin, arenatus = sandy (covered with sand). Referring to black sandy background on back of dried holotype.
Original description: Cheilinus arenatus Valenciennes, 1840 - Type locality: Réunion Island, western Mascarenes, Southwestern Indian Ocean.
Distribution
Red Sea, Indo-West Pacific: East Africa, Seychelles, Madagascar and Mascarenes east to Marshall Islands and Samoa, south to Australia and New Caledonia, north to Philippines, Taiwan, Mariana Islands and Ryukyu Islands (Japan).
Biology
Found solitary in caves of steep outer reef drop-offs with rich invertebrate growth such as large gorgonians or soft corals. Feeds mainly on fishes, shrimps and other crustaceans. Oviparous, distinct pairing during breeding.
