Length at first maturity / Tamaño / Peso / Age

Maturity: L_m 18.7, range 19 - ? cm
Max length : 29.0 cm WD macho / no sexado; (Ref. 109651)

Feed on bottom-dwelling organisms (Ref.50449); primarily small crustaceans, but also small fishes (Ref.58048). Ovoviviparous (Ref. 50449).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialized structures (Ref. 50449). Distinct pairing with embrace (Ref. 205). Gives birth to litters of 1-4 pups; born at 7-10 cm WD. No reproductive synchronicity (Ref.58048).
