Description synthétique
Morphologie | Morphométrie
Épines dorsales (Total): 1; Rayons mous dorsaux (Total): 6; Rayons mous anaux: 10 - 11. Tooth bands of the premaxillae forming a broad arc of uniform width with squared ends and a shallow notch anteromedially (Ref. 78586). Prevomerine tooth patches separated at the midline and accessory tooth plates narrowing posteriorly to a sharp point along a smooth curve (Ref. 78586). Postcleithral process well developed and projecting sharply posteriad (Ref. 78586). Horizontal eye diameter contained 2.7-3.1 times in head length and interorbital width contained 3.8-7.7 times in head length (Ref. 78586).
Demersal during the day; locally abundant between 10 and 25 m depth zones; migrates closer to shore at dusk to feed on chironomid larvae and ostracods; onset of maturity at rather small size (60-70 mm) and extended reproductive period (Ref. 78586).
