Description
Dorsal spines (total): 12-13 (usually: 13); Dorsal soft rays (total): 10-12 (usually: 11); Anal spines: 3; Anal soft rays: 5½-6½; Pectoral fin rays: 15-18 (usually: 16); Pelvic fin rays: I, 5; Gill rakers: 4/1/9-11 = 14-16; Body relatively compressed, body depth: 2.5-2.7 in SL; Lateral line scales: 23-25; Lateral scale series: 49-56; Relatively long fin days in the dorsal fin with length of longest: 30.9-40.5 (mean 35.8) % of SL, in the anal fin with longest ray length: 35.8-44.8 (40.4) % of SL, in the pectoral fin, the ninth ray length: 75.6-113.2 (92.4) % of SL, and in pelvic fin with longest ray: 48.2-71.9 (60.0) % of SL with its posterior tip reaching or extending beyond vertical through posteriormost anal fin soft ray base when depressed; Supraocular tentacle without lateral branches; The postorbital sensory canal absent or not connected to sphenotic spine base at any life history stage. Dorsal fin origin above front edge of opercle; Fin spines longer than body depth, and fin membranes incised nearly to base; Pectoral fins long, reaching past caudal-fin base in juveniles and nearly to caudal fin margin in adults, fin membranes deeply incised for ~½ of fin; Caudal fin rounded. Head spines small but increasing in number with growth; Lachrymal with clusters of spines radiating in 5-6 ridges; Suborbital ridge of juveniles with 1 antrorse and 2 retrorse spines, and spines becoming more numerous with growth. Maxilla extends to vertical between front margins of orbit and pupil. Snout with 1-4 tentacles anteriorly; Flap on anterior nostrils with finely ciliate margin; Supraocular tentacle long, simple, slender, typically twice orbit diameter; Preopercle often with a few tentacles on rear margin near angle of preopercle. Scales on head and body mostly ctenoid, especially well-developed near predorsal area; scales pseudocycloid on underside of head, breast, abdomen and pectoral fin bases. Max. length: 24.0 cm TL, common length: 20.0 cm TL. Depth range: 1 - 30 m.
Color
Body with wide dark orangish or reddish brown bars separated by thin white lines, diverging to form some triangular reddish brown areas dorsally and ventrally; Bars on head and anterior part of body typically darker, and oblique bar with white margins runs through eye; Peduncle with 2 relatively narrow, nearly horizontal, white lines on either side of an oblique reddish band; Pectoral fin rays dark reddish proximally, white distally (no dark spots), rays pale red or pink, membranes nearly transparent.
Etymology
Pteropterus: from ancient Greek, pterón = wing, fin. The name of this genus is attributed to William John Swainson, a British biologist (ornithologist, entomologist, malacologist...) and artist (1789-1855). Georges Cuvier explains that this name comes from their dorsal and pectoral rays, which are excessively elongated, far exceeding the membranes, and from this singular extension comes the generic name Pterois, meaning winged.
radiatus: from Latin, radiatus = radiated, rayed. Referring to long pectoral-fin rays, which extend beyond fin membrane.
Original description: Pterois radiata Cuvier, 1829 - Type locality: Tahiti, Society Islands, French Polynesia, South Pacific.
Distribution
Indo-West Pacific: KwaZulu-Natal (South Africa), East Africa, Persian Gulf, Socotra (Yemen), Seychelles, Comoros and Madagascar, east to Marshall Islands, Line Islands and Marquesas Islands (French Polynesia), north to Kagoshima Prefecture (Japan), south to Western Australia, Queensland (Australia), New Caledonia and Tonga.
Biology
A generally uncommon species that inhabits lagoon and seaward reefs. Prefers rocky reefs and seems to avoid stony corals. Coastal, sometimes in surge zones where in narrow crevices, or along rock-walls in small caves. Found under ledges during the day. Feeds exclusively on small crabs and shrimps. Capable of inflicting a painful sting.
