Biology     Glossary (e.g. epibenthic)

A common inshore to offshore shark found on the continental shelf. Oviparous (Ref. 50449 ). Dental sexual dimorphism exists, with adult males having teeth at least twice as high as adult females as well as much longer and narrower mouths.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449 ). Sexual dimorphism is evident in dentition of male species (Ref. 49562 ). Males have longer teeth with fewer cusps than females (Ref. 51093 ) to make 'courtship biting' more effective (Ref. 49562 ).

Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 6.4 - 15.6, mean 10.6 (based on 202 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00316 (0.00159 - 0.00631), b=3.12 (2.95 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.8   ±0.3 se; Based on diet studies. Resilience (Ref. 69278 ):  Very Low, minimum population doubling time more than 14 years (Fec=2). Vulnerability (Ref. 59153 ):  Moderate to high vulnerability (54 of 100) .
