簡単な記述
形態学 | 形態計測学
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).
