Short description Claves de identificación | Morfología | Morfometría

Median row of teeth is wider transversely to their lengths. Upper jaw has 9 series of teeth. Brown above, brownish white below. Darker towards the tips of the pectorals (Ref. 6902).

A benthopelagic species found inshore over sandy bottoms from nearshore to about 20 m depth. Feeds mainly on molluscs (Ref. 114953). Ovoviviparous (Ref. 50449). Pups 38-48 cm disc width at birth (Ref. 114953).

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

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00463 - 0.02844), b=2.98 (2.76 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.6 ±0.5 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (85 of 100).

Price category (Ref. 80766): Medium.
