Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 12; Espinhos anais: 0; Raios anais moles: 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).

Nível Trófico (Ref.
69278): 3.2 ±0.43 se; based on food items.
Resiliência (Ref.
