Elasmobranchi (squali e razze) (sharks and rays) > Myliobatiformes (Stingrays) > Urolophidae (Round rays)
Etymology: Trygonoptera: Greek, trygon = a sting ray + Greek, pteron = wing, fin (Ref. 45335); imitata: Name from Latin 'imitor', to copy or mimic, refers to its similarity to Trygonoptera mucosa and T. testacea in general appearance resulting in confusion over their identities..

Estimates based on models

Preferred temperature (Ref. 123201): 14.6 - 18.4, mean 16 °C (based on 170 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00692 (0.00399 - 0.01200), b=3.09 (2.93 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

Nutrients (Ref. 124155): Calcium = 4.9 [0.7, 82.5] mg/100g; Iron = 0.193 [0.019, 2.258] mg/100g; Protein = 19.3 [14.0, 24.5] %; Omega3 = 0.349 [0.101, 1.025] g/100g; Selenium = 11.3 [2.1, 60.5] μg/100g; VitaminA = 11.2 [0.8, 144.1] μg/100g; Zinc = 0.455 [0.031, 5.072] mg/100g (wet weight);
