Short description Morphology | Morphometrics
A ray-shaped shark. Head narrowing to distinct neck at base of pectoral fins (Ref. 26938).
Occurs on the outer continental shelf and the upper slope. Found from shoreline to depths of 1,375 m (Ref. 26938). Benthic burrower; feeds on small bottom fishes, crustaceans and mollusks (Ref. 27549). Ovoviviparous. Will bite when captured and can inflict nasty lacerations with its trap-like jaws and pointed teeth.
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Ovoviviparous, embryos feed solely on yolk (Ref. 50449).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00281 - 0.01956), b=3.04 (2.80 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278): 4.5 ±0.6 se; Based on diet studies.
Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153): High to very high vulnerability (71 of 100) .
