Quote Turner et al. (Ref. 55949): "We consider that both R. leptosoma and R. melanotus are probably junior synonyms of R. esox. If this is accepted, R. esox can be considered the most distinctive and readily identified species of the genus."

Short description Claves de identificación | Morfología | Morfometría

Diagnosis: elongated and very streamlined shape; body in cross-section more rounded than congenerics; frequently exhibits a horizontal stripe (Ref. 55949).

Inhabits the open water (Ref. 5595). Widely distributed in shelf and rocky reef zones, usually where the bottom is fairly shallow; rarely found offshore; small juveniles widely distributed in the littoral zone in swampy, sandy and rocky habitats; adults regularly encountered near sandy beaches in the shallows (Ref. 55949). Feeds on fish species like the small Utaka and the lake sardine Usipa (Engraulicypris sardella) (Ref. 5595).
