Remarks | Lives in mangrove coast, occurring in subtidal sections of tidal channels at low tide and use the intertidal mangrove creeks during high tide. Occurs in estuaries and freshwater bodies, reaching some distance inland (at least 17 km up the Suriname River; to above Santarem on the Amazon). The short and few gillrakers suggest predatory feeding on small fishes, etc. Diet changed with fish size, smaller fish sizes fed on several food items, fish >13 cm SL fed exclusively on natantia and teleostei (Ref. 56005). Sciaenidae and Mugilidae were dominantly selected as their prey items (Ref. 56005). |
