Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 30 m (Ref. 5213). Tropical; 29°N - 34°S, 28°E - 157°W (Ref. 5222)
Indo-West Pacific: Natal, South Africa to the central Pacific. Not known from the Red Sea nor Persian Gulf.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 54.9 cm TL male/unsexed; (Ref. 125599); common length : 25.0 cm TL male/unsexed; (Ref. 9137); max. published weight: 3.8 kg (Ref. 125599)
soft rays: 8. A single large black blotch along middle of dorsal fin base (Ref. 37816), which can be turned off (Ref. 48635); further characterized by head, body and fins having numerous close-set polygon shaped dark brown spots; broad zone along side of body with ctenoid scales, cycloid scales elsewhere; body with auxiliary scales; greatest depth of body 2.9-3.4 in SL; rounded caudal fin; short pelvic fins, 2.0-2.6 in head length (Ref. 90102); head length 2.2-2.4 in SL; flat or slightly concave interorbital area; rounded preopercle, serrae mostly covered by skin; straight or slightly convex upper edge of operculum; subequal posterior and anterior nostrils; maxilla reaches to or past vertical at rear edge of eye; 3-5 rows of teeth on midlateral part of lower jaw, inner teeth about twice as long as outer ones (Ref. 89707).
Occur in outer reef flats and shallow lagoon (Ref. 37816). Reported to be taken in a trawl, thus presumably caught somewhat deeper than 7 m. Also reported to occur in reefs at a depth of about 30 m (Ref. 5213). Because of its small size and apparent rarity, it is of little or no commercial importance. Solitary (Ref 90102).
