Marbled whipray
The marbled whipray (''Himantura oxyrhyncha'') is a little-known species of stingray in the family Dasyatidae, native to several freshwater rivers in Southeast Asia. This species has an oval pectoral fin disc with an elongated, pointed snout and a very long, whip-like tail without fin folds. It is characterized by numerous heart-shaped dermal denticles and tubercles on its upper surface, as well as a reticulated pattern of brown blotches on a light background. The maximum recorded disc width is . The marbled whipray has been assessed as Endangered by the International Union for Conservation of Nature (IUCN); it is heavily threatened by fishing and habitat loss, degradation, and fragmentation.
==Taxonomy==
French zoologist Henri-Emilé Sauvage originally described the marbled whipray as ''Trygon oxyrhynchus'' based on a female specimen caught near Saigon, Vietnam, in an 1878 volume of the scientific journal ''Bulletin de la Société philomathique de Paris''. In 1913, Samuel Garman synonymized this species with ''Himantura uarnak'', a judgment that remained unquestioned in subsequent literature until Maurice Kottelat referenced the name in his 1984 review of Indochinese fishes. This species may also be referred to as the longnose marbled whipray or the marbled freshwater stingray.
