izu stingray
The Izu stingray (''Dasyatis izuensis'') is a little-known species of stingray in the family Dasyatidae, endemic to the Izu Peninsula of Japan. Found in shallow coastal waters, it is a fairly small species with a smooth, golden-brown, diamond-shaped pectoral fin disc and a whip-like tail with a low keel above and fin fold beneath. The fin fold is white, distinguishing the Izu stingray from all other Pacific members of its family. The International Union for Conservation of Nature (IUCN) has assessed this rare species as Near Threatened.
==Taxonomy==
The Izu stingray was described by Kiyonori Nishida and Kazuhiro Nakaya in a 1988 issue of the ''Japanese Journal of Ichthyology''. Its specific epithet ''izuensis'' refers to where the type specimen, a wide adult male, was caught.
