Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 10; Dorsale zachte stralen (totaal) : 9; Anale stekels: 3; Anale zachte stralen: 8. The body is light tan or olive to brown, becoming lighter below. the centers of the scales are often lighter than the background color. The head, often, has several broad indistinct vertical and diagonal light and dark bands. Sometimes there are white spots below the eye. The posterior edge of the operculum is dark brown. An orange-yellow stripe is on the lower part of the side with two additional more faint orange-yellow stripes above and one below this stripe. The fins are whitish or tan, sometimes mottled.
Body shape (shape guide): fusiform / normal; Cross section: oval.

Biologie     Verklarende woordenlijst (bv. epibenthic)

Found over seagrass beds (Ref. 41878), sand and rubble areas of lagoons and reefs (Ref. 30573). Found singly or in groups (Ref. 9710). Juveniles on weedy reefs (Ref. 48635). Feed on mollusks, crustaceans, and echinoderms (Ref. 30573). One of the commonest lethrinids along the coast of east Africa (Ref. 4369). Marketed fresh (Ref. 9775).

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

Gonochorism is inferred for this species as sizes of males and females overlapped and male gonad morphology is typical of secondarily derived testes (Ref. 103751). This may be supported further by the study of Ebisawa etal (2006) which characterised sexual pattern for this species as juvenile hermaphroditism indicating that sexual transition occurred before ovarian maturation, a case for non-functional hermaphroditism in Ref. 103751.
