Etymology: Atherina: Greek, atherina, the Greek name for the eperlane; 1770 (Ref. 45335). More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; pelagic-neritic. Subtropical; 27°S - 35°S
Southeast Atlantic: restricted from Lüderitz, Namibia to northern Natal, South Africa.
Length at first maturity / Size / Weight / Age
Maturity: Lm 4.0  range ? - ? cm
Max length : 11.0 cm SL male/unsexed; (Ref. 7248)
Forms schools along the coast and in estuaries, especially during spring (Ref. 3302). Also found in coastal lakes (Ref. 7248). Small individuals filter out small organisms such as phytoplankton and rotifers. Above 3.5 cm TL, it feeds mostly on crustaceans especially amphipods taken from the water column as well as off the bottom. Preyed upon by fishes and birds (Ref. 7248).
