Indo-West Pacific: widespread, including the Red Sea, Arabian (Persian) Gulf, East Africa to Sri Lanka, to the Ryukyu Islands and Papua New Guinea. Also recorded from Micronesia (Ref. 3807) and French Polynesia (Ref. 4517) but these are probably misidentifications of Lethrinus olivaceus.

Length at first maturity / Size / Weight / Age

Maturity: Lm 29.1  range ? - ? cm
Max length : 80.0 cm TL male/unsexed; (Ref. 48635); common length : 40.0 cm TL male/unsexed; (Ref. 2295); max. published weight: 4.9 kg (Ref. 40637)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 8. The snout is moderately long, its dorsal profile slightly concave. Body color is bluish gray or brown often with scattered irregular dark blotches on sides; sometimes three dark streaks radiate forward from the eye. The fins are pale or orangish.
Body shape (shape guide): fusiform / normal; Cross section: oval.

Biology     Glossary (e.g. epibenthic)

Found over sandy areas near coral reefs (Ref. 30573). Feeds on fish, crustaceans, cephalopods, and polychaetes. Swims in small schools sometimes together with L. olivaceous. Utilized as a food fish. Maximum depth reported taken from Ref. 9773.

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29.1, mean 28.1 °C (based on 1954 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.01108 - 0.01643), b=2.97 (2.93 - 3.01), in cm total length, based on LWR estimates for this species (Ref. 93245).
