Morfologia | Morfometria
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
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
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. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00461 - 0.02857), b=2.98 (2.76 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179
): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).
Vulnerability (Ref. 59153
): High to very high vulnerability (68 of 100) .
