Etymology: Lethrinus: Greek, lethrinia, a fish pertaining to genus Pagellus. More on author: Smith.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 5 - 220 m (Ref. 2295). Tropical; 14°N - 22°S
Indian Ocean: Tanzania, northern Madagascar, Chagos, Andamans and southwestern Indonesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 76.0 cm TL male/unsexed; (Ref. 2295); common length : 50.0 cm TL male/unsexed; (Ref. 2295)
Solitarily inhabits sand, rubble, and weed areas near corals (Ref. 90102) in deep reefs. Feeds on crustaceans and small fishes. Gonads in spawning state have been observed in October. This species is not well represented in museums due to the relatively large capture size for most specimens (Ref. 2295). Also caught with handlines (Ref. 9775).
