Platyrhina sinensis; Print; The fanray (Platyrhina sinensis) is a species of ray in the family Platyrhinidae that lives in the western Pacific Ocean. It typically grows to a length of 30-50 centimetres (12-20 in) and a weight of 200-500 grams (7.1-17.6 oz); with a brown upperside and a white underside. It eats fish and crustaceans and has poor mobility. Males live to age five and females to age twelve; with both sexes maturing between two and five years. The species is found in China; Japan; Taiwan; Korea; Vietnam; and possibly Indonesia; in waters shallower than 100 metres (330 ft). It is probable that its population is declining due to being caught as a bycatch.; 1700-1880
