A benthic species. Found on coastal to offshore on continental shelf in open sandy, muddy and silty habitat, including estuaries and intertidal zones. Mainly feeds on bony fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Maturity size 35-42 cm WD (males) and 44-46 cm WD (females); hatch size 22-25 cm DW. Produces litters of 1-6 pups (Ref. 114953). Caught by shrimp trawlers.

Life cycle and mating behavior Maturities | पुनरुत्पत्ति | Spawnings | Egg(s) | Fecundities | लार्वा

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): 25.6 - 28.7, mean 27.7 (based on 360 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00352 - 0.01710), b=3.09 (2.89 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (Fec assumed to be <10).
