Found in mangrove swamps and estuaries (Ref. 9840). Feeds on shellfish (Ref. 6871), worms, crabs and other crustaceans (Ref. 114953). Size could possibly reach 160 cm DW (Ref. 114953). Ovoviviparous (Ref. 50449). Maturity size ca. 41 cm WD (males) and 63 cm WD (females); hatch size ca. 11 cm WD (Ref. 114953).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | 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). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 26.9 - 29, mean 28 (based on 130 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00646 (0.00265 - 0.01571), b=3.06 (2.86 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.50 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (78 of 100).

Price category (Ref. 80766): Low.
