Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais (total) : 12; Espinhos anais: 0; Raios anais : 8. Head length less than 4.2 times in standard length; head longer than pectoral-ventral length; anal fin length less than 0.75 times in head length; lower lobe of caudal fin less than 1.25 times in head length; eye diameter at least 5 times in head length; maximally 32 scales on lateral line; silvery.
Occurs over muddy, sandy and rocky substrates, preferably in water deeper than 6 m. A real benthivore: specimens smaller than 10 cm FL mainly eat insect larvae, but also zooplankton and ostracods. With increased size, adult insects, mollusks and detritus also become important (Ref. 35835).
