Chinese stingray
The Chinese stingray, ''Dasyatis sinensis'', is a little-known species of stingray in the family Dasyatidae, found in the northwestern Pacific Ocean off the coasts of China and Korea. This species is characterized by a band of small dermal denticles running along the upper surface of its diamond-shaped pectoral fin disc, from the snout to the tail spine. It can grow to across and long. The Chinese stingray is taken incidentally in bottom trawls and is one of the three most commonly marketed stingrays in China. At present, the International Union for Conservation of Nature (IUCN) does not have sufficient information to assess its conservation status beyond Data Deficient.
==Taxonomy==
The Chinese stingray was originally described as ''Trygon sinensis'' by Austrian Franz Steindachner, in an 1892 volume of the scientific journal ''Denkschriften der Mathematisch-Naturwissenschaftlichen Classe der Kaiserlichen Akademie der Wissenschaften in Wien''. Subsequent authors synonymized the genus ''Trygon'' with ''Dasyatis''. The type specimen is a male across, collected from Shanghai, China.〔Nishida, K. and K. Nakaya (1990).
