Elasmobranchii (sharks and rays) > Myliobatiformes
(Stingrays) > Urolophidae
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..
