Gymnura australis (Australian Butterfly Ray) is a species of butterfly rays in the family butterfly rays. Individuals can grow to 73 cm. They rely on pectoral fin oscillation to move around.
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.
Definition: A habitat that is in or on a sea or ocean containing high concentrations of dissolved salts and other total dissolved solids (typically >35 grams dissolved salts per litre).
