Ecology of Sternopygus macrurus
 
Main Ref. Boujard, T., M. Pascal, F.J. Meunier and P.-Y. Le Bail, 1997
Remarks Occurs in swamps, creeks, and river with lentic waters. Preys on small invertebrates, particularly the larvae of aquatic insects (Ref. 12225). Males persistently defend their territory and apparently make electric signals (by increased electric organ discharge (EOD) rates and interruptions thereof) to females passing by to draw in a spawning partner (Ref. 10605). Mature females' EODs are of higher frequencies than mature males (Ref. 10645).
