Elasmobranchii (sharks and rays) > Myliobatiformes (Stingrays) > Urotrygonidae (American round stingrays)
Etymology: Urobatis: Greek,oura = tail + Greek, batis, batidos = a ray (Raja sp.) (Ref. 45335).

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; demersal; depth range 0 - 91 m (Ref. 12951), usually 1 - 21 m (Ref. 96339). Subtropical; 43°N - 7°N, 125°W - 79°W (Ref. 55315)

Size / Weight / Age

Maturity: L_m ? range ? - 24 cm
Max length : 58.0 cm TL male/unsexed; (Ref. 40637); max. published weight: 1.4 kg (Ref. 4699)

Occurs on sand, rubbly or mud bottom off beaches and in bays and sloughs; near seagrasses, usually shallower than 15 m. Adult females profuce 2 litters of up to 6 pups per year (Ref. 2850, 114953), sometimes around rocky reefs (Ref. 12951). Feeds on benthic invertebrates and small fishes.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Male grasps disc margin of female, flips under her, and inserts a clasper. Mating lasts about 5 minutes.

Estimates based on models

Preferred temperature (Ref. 123201): 17.2 - 28.5, mean 23.6 °C (based on 60 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02291 (0.01108 - 0.04738), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.1 se; based on diet studies.

Generation time: 18.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (K=0.15).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 13.1 [1.7, 269.5] mg/100g ; Iron = 0.7 [0.1, 8.3] mg/100g ; Protein = 20 [15, 25] % ; Omega3 = 0.187 [0.058, 0.564] g/100g ; Selenium = 21 [4, 100] μg/100g ; VitaminA = 8.69 [0.62, 112.29] μg/100g ; Zinc = 0.744 [0.051, 8.704] mg/100g (wet weight);
