Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Sexual dimorphism; males form an elongated irregular bent first dorsal spine. They use barbels otherwise hidden in a fold of the upperlip to get a hold on the female while they insert their pseudopenis formed by the anal fin. Type of spawning (ovipar or vivipar) is unknown.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00341 - 0.01611), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=1, Fec<10,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).
