Tamaño / Peso / Age

Maturity: L_m ? range ? - ? cm
Max length : 7.8 cm SL macho / no sexado; (Ref. 28981)

Usually live 305 m or more below the surface but move upward in the water at night, sometimes to relatively shallow depths. Are believed to be rapid swimmers, skillful at avoiding nets, which would account for the scarcity of large adults in research collections. Juveniles feed heavily on crustaceans, while adults feed mainly on fish (Ref. 4525).

Estimates based on models

Preferred temperature (Ref. 115969): 0.3 - 12.8, mean 4.1 (based on 226 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00347 (0.00144 - 0.00836), b=3.15 (2.94 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.8 ±0.58 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (K=0.86).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
