Bennett's stingray : ウィキペディア英語版 | The Bennett's stingray or frilltailed stingray (''Dasyatis bennetti'', often misspelled ''benetti'' or ''bennettii'') is a little-known species of stingray in the family Dasyatidae, with a wide but ill-defined distribution in the Indian and Pacific Oceans. This species is characterized by a rhomboid, yellow-brown pectoral fin disc with a fairly long snout, and an extremely long tail with a correspondingly long ventral fin fold. It measures up to across. It feeds on fish, and is aplacental viviparous. It is likely caught by demersal fisheries, but the International Union for Conservation of Nature (IUCN) does not yet have sufficient information to assess its conservation status.==Taxonomy==German biologists Johannes Peter Müller and Friedrich Gustav Jakob Henle described the Bennett's stingray as ''Trygon bennettii'' in their 1839–1841 ''Systematische Beschreibung der Plagiostomen''. They referenced three specimens as the species syntypes: only the one from China remains, while another from Trinidad and a third of unknown provenance have been lost. Later authors synonymized the genus ''Trygon'' with ''Dasyatis''.Eschmeyer, W.N. and R. Fricke, eds. (''bennetti, Trygon'' ). Catalog of Fishes electronic version (January 15, 2010).
