Gymnura is a genus of Myliobatiformes in the family butterfly rays. They rely on pectoral fin oscillation to move around.

  • 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.
