The International Union for Conservation of Nature (IUCN) has listed this species as Data Deficient and recommended further study.

Russian ichthyologist Georgii Ustinovich Lindberg published the description of the giant stumptail stingray in his and Soldatov's 1930 A Review of the Fishes of the Far-Eastern Seas.

The tail is distinctive, being shorter than the disc and ending bluntly rather than tapering to a filament as in other Dasyatis species.

The skin is largely smooth, except for numerous small dermal denticles over the posterior portion of the disc, the pelvic fins, and the base of the tail.

[1] As only two specimens have been found thus far, the International Union for Conservation of Nature (IUCN) lacks sufficient information to assess the giant stumptail stingray beyond Data Deficient.
