Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Western Atlantic: southern New England, USA to the Gulf of Mexico, Jamaica and Venezuela. Also in Columbia (Ref. 26938).

Biology     Glossary (e.g. epibenthic)

Occurs on the outer continental shelf and the upper slope. Found from shoreline to depths of 1,375 m (Ref. 26938). Feeds on small bottom fishes, crustaceans and bivalves. Ovoviviparous. Will bite when captured and can inflict nasty lacerations with its trap-like jaws and pointed teeth.

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=0.00724 (0.00272 - 0.01929), b=3.04 (2.80 - 3.28), 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 (74 of 100) .
Price category (Ref. 80766):   Medium.
