Biology     Glossary (e.g. epibenthic)

Commonly found off beaches and over sand flats in shallow water. Also found offshore down to 85 m (Ref. 9862). Feeds mainly on crabs and shellfish (Ref. 6871). Ovoviviparous (Ref. 50449).

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 based on models

Preferred temperature (Ref. 123201): 15 - 20.1, mean 17.4 °C (based on 236 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00119 - 0.01269), b=3.08 (2.83 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.55 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (83 of 100).
Nutrients (Ref. 124155):  Calcium = 4.25 [0.47, 67.92] mg/100g; Iron = 0.393 [0.033, 4.254] mg/100g; Protein = 21.5 [16.2, 26.7] %; Omega3 = 0.113 [0.037, 0.324] g/100g; Selenium = 15.7 [2.8, 83.7] μg/100g; VitaminA = 14.1 [1.2, 162.4] μg/100g; Zinc = 0.464 [0.031, 5.171] mg/100g (wet weight);
