Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 12; Épines anales: 0; Rayons mous anaux: 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).
