Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 2 - 3; Mjukstrålar i ryggfenan (totalt): 10-12; Taggstrålar i analfenan 1; Mjukstrålar i analfenan: 8 - 10; Ryggkotor: 28 - 29. The species has a spinulated posterior
and lower margins of praeoperculum, posterior margin of the praeoperculum is usualy unspinulated or in a small number of fish there can be one spinule; insertion of ventral fins is in front of the vertical of the posterior margin of pectoral fin insertion; upper jaw in most fish does not reach the vertical of the posterior eye margin; usually 3 (seldom 2) spiny and 10–12 soft rays in dorsal fin; 8–10 soft rays in anal fin; 23–25 rakers at the first branchial arch; vertebrae 28–29; and pyloric caeca 4–6.
Specimens seined with unclosing fishing gear (Ref. 84090).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00451 - 0.02668), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
