Life cycle and mating behavior
Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve
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): PD
50 = 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
Resilienza (Ref.
120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Assuming tm=1, Fec<10,000).
Fishing Vulnerability (Ref.
