Short description Morphology | Morphometrics

Dark grey to blackish brown above, white to yellowish below (Ref. 11228).

Biology     Glossary (e.g. epibenthic)

Demersal on both insular and continental shelves, but now thought to be extinct through much if its original range (Ref. 114953). Inshore and intertidal species known to enter freshwater in some areas (Ref. 9859). Found in shallow bays, estuaries, and lagoons (Ref. 11228). Often on the bottom with its saw elevated at an angle to the body axis (Ref. 9859). Feeds on fishes and shellfishes (Ref. 58784). Ovoviviparous (Ref. 50449). Reaches maturity after 9 years. Females have litters of approximately 12 pups. Maturity size unclear, possibly near 430 cm TL; born at approximately 80 cm TL (Ref. 114953). Flesh considered tasty (Ref. 11228).

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

Ovoviviparous, embryos feed solely on yolk (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 29.3, mean 28.5 °C (based on 2833 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5234   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00198 - 0.01270), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 12.4 [3.1, 55.8] mg/100g; Iron = 0.505 [0.120, 1.454] mg/100g; Protein = 19.3 [17.2, 21.4] %; Omega3 = 0.11 [0.04, 0.28] g/100g; Selenium = 81.8 [22.3, 265.0] μg/100g; VitaminA = 3.88 [1.41, 10.36] μg/100g; Zinc = 0.61 [0.29, 1.12] mg/100g (wet weight);
