Biology     Glossary (e.g. epibenthic)

A moderately common benthic and epibenthic shark found on the continental shelf (Ref. 247, 43278). Occurs from close inshore to about 93 m depth (Ref. 247, 43278). Feeds primarily on sea urchins, but also on crustaceans, mollusks, and small fishes (Ref. 31369). Oviparous, egg cases spirally flanged and with long tendrils (Ref. 6871). Hatches at about 22 cm (Ref. 6871).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5059   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.53 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (tm=11.8).
Vulnerability (Ref. 59153):  Very high vulnerability (87 of 100) .
Price category (Ref. 80766):   Unknown.
