Length at first maturity / Tamaño / Peso / Age

Maturity: L_m ?, range 48 - ? cm
Max length : 91.0 cm TL macho / no sexado; (Ref. 2850)

Inhabits fine sand to mud bottom, often near kelp beds and sometimes abundant on mud flats of coastal bays. Often buries itself in bottom sediments. Ranges from the intertidal zone to 50 m depth (Ref. 12951). Solitary or in small groups, gathers in shallow bays, lagoons, and off beaches (Ref. 12951, Ref. 114953). Feeds on small sand-dwelling crustaceans, worms and mollusks. Ovoviviparous (Ref. 50449), with 1 to 15 pups in a litter (Ref. 48844), mainly in August (Ref. 114953). Possesses ampullary electroreceptors with a region of maximum sensitivity of 5-15 Hz (Ref. 10011).

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 specialised structures (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 115969): 15.3 - 23.1, mean 20.6 (based on 38 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.4 ±0.42 se; based on food items.

Resiliencia (Ref. 120179): Muy bajo, población duplicada en un tiempo mínimo superior a 14 años (Fec = 1).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).
