Biology     Glossary (e.g. epibenthic)

Found near shore on sandy-mud bottoms (Ref. 11230, 30573). Reported to occur offshore (Ref. 58784). Feeds on small benthic animals. Ovoviviparous (Ref. 50449). The best edible fish in the family, served in raw slices or hard boiled with seasonings (Ref. 637). Dried fins used for shark-fin soup (Ref. 30573).

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

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 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=0.00324 (0.00159 - 0.00657), b=3.11 (2.93 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.37 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (52 of 100) .
Price category (Ref. 80766):   Low.
