Source-derived summary

The round fantail stingray (Taeniurops grabatus) or round stingray, is a poorly known species of stingray in the family Dasyatidae. It inhabits sandy, muddy, or rocky coastal habitats in the eastern Atlantic Ocean and the southern Mediterranean Sea. This dark-colored ray typically reaches a width of 1 m (3.3 ft), and can be identified by its nearly circular pectoral fin disk, short tail, and mostly bare skin. The round fantail stingray hunts for fishes and crustaceans on the sea floor, and exhibits an aplacental viviparous mode of reproduction. The International Union for Conservation of Nature (IUCN) has assessed the conservation status of this species as Near Threatened.

Taxonomy

French naturalist Étienne Geoffroy Saint-Hilaire originally described the round fantail stingray in 1817 as Trygon grabatus, from the Latin grabatus meaning "bed". His account was published in the first volume of the folio Poissons du Nil, de la mer Rouge et de la Méditerranée. Subsequent authors moved this species to the genus Taeniura. No type specimens are known.

Distribution and habitat

The round fantail stingray is found on the tropical to subtropical waters of the eastern Atlantic from Mauritania to Angola, as well as off the Canary Islands, Madeira, and Cape Verde.

Editorial summary

The public source identifies “Round fantail stingray” as species of stingray (Taeniura grabata). This brief keeps that definition visible, then builds a research path around Round, fantail and stingray.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1817—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Round, fantail and stingray providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Round fantail stingray”, the useful work is to connect “species of stingray (Taeniura grabata)” to the records capable of establishing context and consequence.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q4546818. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1817.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
