Hypanus marianae

Common Name

Brazilian Reef Stingray

Year Described

Gomes, Rosa & Gadig, 2000


A short-snouted species of Dasyatis with a broad rhomboidal disk. Eyes and spiracle large (interorbital distance about equal to eye diameter). Mouth small. Tips of pectoral fins narrowly rounded. Pre-orbital length much longer than distance between the spiracles, with slightly convex margins of snout. The dorsal surface has a line of 2-18 medial and one scapular denticle. Both dorsal and ventral finflaps well developed with ventral finfold twice as high as dorsal. Tail relatively short (<2 times DW) and whip-like with spine close to tail base. Pelvic fins protrude beyond pectorals.


Dorsum olive to yellowish brown with yellowish to whitish marbled markings concentrated on the center of the disk. A patch of orange around each eye and spiracle. Tail white with dark finfolds and filamentous tip. Underside pale with semi-symmetrical random dark blotches.


Maximum size to 31cm DW.


Shallow coastal waters around reefs from 2-15m.


Northeastern Brazil to Bahia state (Abrolhos Islands).

Other Notes

The name Dasyatis macrophthalma was mistakenly applied to this species and was corrected in Rosa et al. (2000).

Moved from Dasyatis to Hypanus based on morpological and molecular data (Last et al., 2016).
