Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 15 - 18; Épines anales: 0; Rayons mous anaux: 17 - 20; Vertèbres: 55 - 58. Gill rakers usually 32 or less on the first arch and 25 or less on the second arch. Relatively longer upper jaw (usually longer than wide) and lower jaw (usually longer than head length), especially at larger sizes.
Occurs in inshore waters. Forms schools for spawning during mid summer (Ref. 9258). Feeds mainly on larger zooplankton like mysids, crab larvae and polychaete larvae (Ref. 26966).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.2 ±0.3 se; based on diet studies.
Résilience (Ref.
