Biology     Glossary (e.g. epibenthic)

Common in estuaries (Ref. 4832). Feed on bottom-dwelling organisms (Ref.50449)- primarily small crustaceans, but also small fishes (Ref.58048). Ovoviviparous (Ref. 50449). Landed in very large quantities as by-catch in the bottom trawl and trammel fisheries. Utilized for its meat, but of limited value due to its very small size (Ref.58048).

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 specialized structures (Ref. 50449). Distinct pairing with embrace (Ref. 205). Gives birth to litters of 1-4 pups; born at 7-10 cm WD. No reproductive synchronicity (Ref.58048).

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=0.01202 (0.00492 - 0.02938), b=3.03 (2.81 - 3.25), 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 (Assuming fecundity<100).
Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100) .
Price category (Ref. 80766):   Low.
