An oceanic species which occurs near surface. Adults form very big schools (Ref. 9306). Feed on small fishes and planktonic organisms (Ref. 9306). Oviparous, with planktonic larvae (Ref. 36576). Eggs are attached to floating objects via filaments (Ref. 36576). Found in markets of Panama (Ref. 9306).
