Hemitrygon sinensis is a species of stingray and lives in the northwestern Pacific off the coasts of China and Korea .
features
Hemitrygon sinensis reaches a total length of a maximum of 82 cm with a slice width of up to 40 cm. It has a diamond-shaped pectoral fin disc that is about as wide as it is long. The tail is whip-like, a little less than twice as long as the disc and usually has a poison sting. The upper side is gray, lighter on the edges of the fins; the underside is gray-white.
Way of life
Little is known about the way of life of the ray. Like most stingrays, it is believed to be ovoviviparous . It is often caught as bycatch in trawls and is also recycled, especially in China.
Systematics
The ray species was described in 1892 by the German ichthyologist Franz Steindachner under the scientific name Trygon sinensis , later assigned to the genus Dasyatis . When the Dasyatidae was revised in mid-2016 , the species was placed in the genus Hemitrygon .
