Gymnura japonica (Japanese Butterfly Ray) is a species of Myliobatiformes in the family Gymnuridae. They are listed as vulnerable by IUCN. Individuals can grow to 100 cm. They rely on pectoral fin oscillation to move around.

URI: http://eol.org/schema/terms/vulnerable
Definition: A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable, and it is therefore considered to be facing a high risk of extinction in the wild.

URI: https://eol.org/schema/terms/pectoral_oscillation
Definition: a type of pectoral-fin-based swimming, also known as mobuliform locomotion. Lower frequency than fin undulation; can be described as the production of less than half a wave on the fin, similar to a bird wing flapping. Pelagic stingrays use oscillatory locomotion.
