Etymology: Brevitrygon: Derived from brevis (Latin), meaning short and trygṓn (Greek τρυγών), meaning stingray, in allusion to the short, semi-rigid tails of these stingrays; imbricata: Name fro Latin 'imbricata' meaning overlapping each other, referring to the secondary denticle band, which is very narrow over the branchial region and abdomen in this species.

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

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). Examined adult males 17.1 cm DW (32.0 cm TL) - 20.5 cm DW (39.8 cm TL); females 13.8 cm DW (25.6 cm TL) - 20.4 cm DW (39.6 cm TL); early juveniles (USNM 222564, immature male 12.0 cm DW and female 8.8 cm DW) have lost umbilical scars. Reported maximum disc width 30.0 cm (Ref. 11312) was found excessive (Ref. 130662).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

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=0.01698 (0.01043 - 0.02765), b=3.12 (2.97 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (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.

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (K=0.59; Fec=1).

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

Preiskategorie (Ref. 80766): Low.
