Short description
Hình thái học | Sinh trắc học
Diagnosis: It hardly differs from the European anchovy (Engraulis encrasicolus); of other anchovies in southern and eastern African waters, species of Stolephorus have 3 to 7 sharp needle-like scutes along the belly, while species of Thryssa have compressed bodies and a keel of scutes along the belly (Ref. 189).
Pelagic in coastal waters, but down to a depth of about 400 m (Ref. 30573). It feeds on planktonic organisms (Ref. 30573). Larvae and juveniles were observed to be selective, raptorial carnivores and switched to non-selective filter feeding omnivory when adults. Caught with purse seines in South Africa and Namibia (Ref. 80687).
