Краткое описание определительные ключи | морфология | морфометрия

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

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).

Estimates based on models

Preferred temperature (Ref. 115969): 24.6 - 29.3, mean 28.5 (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

устойчивость к внешним воздействиям (Ref. 120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Категория цены (Ref. 80766): Medium.
