Tamaño / Peso / Age

Maturity: L_m ? range ? - ? cm
Max length : 15.0 cm SL macho / no sexado; (Ref. 36377)

Spawns on the bottom. A male will spawn with more than one female if there is more than one ripe female around. If not, he is satisfied to spawn with one partner and to stay with one female forever (Ref. 12251). Maximum length 25 cm TL (Ref. 2060).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Eggs are deposited on substrate and covered with sand; female protects clutch and takes larvae into the mouth after hatching; larvophile mouth brooder. This corrects previous information from Ref. 2060.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01778 (0.01063 - 0.02975), b=2.97 (2.83 - 3.11), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nivel trófico (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

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

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