Found in coastal marine, brackish and freshwater areas. Feeds on aquatic plants, (i.e. water hyacinths and marine seagrasses, algae, parts of mangrove trees, floating and shoreline vegetation); invertebrates (i.e. tunicates); and fish they remove from fishing nets (Ref. 1394). Found in coastal marine, brackish and freshwater areas (Ref. 1394), where primary habitat consists of rivers, coastal lagoons and bays and mangrove islands (Ref. 86755). Feeds on aquatic plants, (i.e. water hyacinths and marine seagrasses, algae, parts of mangrove trees, floating and shoreline vegetation); invertebrates (i.e. tunicates); and fish they remove from fishing nets (Ref. 1394).
