(Sea basses: groupers and fairy basslets) > Epinephelinae
Etymology: Variola: Latin, variolus = pustule, pock (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 3 - 300 m (Ref. 89972), usually 15 - ? m (Ref. 5222). Tropical; 30°N - 37°S, 30°E - 23°W (Ref. 5222)
Indo-Pacific: Red Sea to South Africa and the Pitcairn Islands, north to southern Japan, south to New South Wales, Australia. Not found in the Persian Gulf nor in Hawaii.
Length at first maturity / Size / Weight / Age
Maturity: Lm 47.6, range 41 - ? cm
Max length : 83.0 cm TL male/unsexed; (Ref. 40637); common length : 75.0 cm TL male/unsexed; (Ref. 5450); max. published weight: 12.0 kg (Ref. 5222)
soft rays: 8. Juveniles conspicuous by the white line over the snout (Ref. 48635). Further characterized by yellowish brown to orange red color with numerous red, pink and lavander small spots and short dashes; pectoral, dorsal, anal and caudal fins with yellow posterior margin; front of jaws with pair of large canines; 1-2 large curved canineson side of lower jaw; elongate body, greatest depth 2.8-3.2 in SL; lunate caudal fin (Ref. 90102).
Usually seen in clear-water areas at depths below 15 m, and prefers islands and offshore reefs rather than continental shores. Feeds mainly on fishes, and on crabs, shrimps and stomatopods. It is highly appreciated for the quality of its flesh. It may not be sold in Mauritius because of cases of ciguatera poisoning (Ref. 11888). In the Hong Kong live fish markets (Ref. 27253).
