Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 15 - 17; Rayons mous dorsaux (Total) : 19 - 21; Rayons mous anaux: 19 - 22; Vertèbres: 45 - 46. Interpelvic process small and bifid. Body covered with small scales. Lateral line without auxiliary branches anteriorly, gradually curving down toward caudal peduncle. Intestine with 2 folds and 3 limbs. Juveniles have spots but develop adult pattern of interrupted lines by the time they reach 40 cm.
Neritic species (Ref. 5313). Forms large schools in the Zanzibar Channel from March to September. Feeds mainly on anchovies (Anchoviella sp.), clupeids (Amblygaster sp., Sardinella fimbriata, Sardinella perforata [= Sardinella albella), other small fishes, squids, and mantis shrimps.
