Maturity: Lm ?  range ? - ? cm
Apparently planktophagic, with Drepanopus forcipatus (calanoid copepod) as its main food; has very low fecundity (only 71 maturing ova found as mean value); and has four parasites - two species of Acanthocepha (larvae of Corynosomia sp. And adults of Hypoechinorhyinchus sp.), one undetermined Trematoda and a larva of undetermined ectoparasitic copepod (Ref. 56210).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 1.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
