Short description Morphology | Morphometrics

Disc width equal to disc length; tail shorter than body; ventral surface of disc entirely white (Ref. 12693).

Found in inshore coastal waters (Ref. 30573). Typically found in estuarine habitats, but also reported from the Great Lake. The single record from the Great Lake may in fact refer to Dasyatis laosensis. Young and adults feed on benthic invertebrates (Ref. 12693). Ovoviviparous (Ref. 124). Feeds on bottom-living invertebrates (Ref. 68964). May grow to a maximum of 140 cm disc length in the sea (Ref. 43081). Juveniles may be present in mangroves (Ref. 43081).

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). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 26.4 - 29.2, mean 28.4 °C (based on 1288 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00901 - 0.02543), b=3.15 (3.00 - 3.30), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 se; based on food items.

Generation time: 1.9 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (K=0.59; Fec=1).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).

Price category (Ref. 80766): Low.
