Steve Westnedge plays in saxophone for a Leopard Seal known as "Casey" as part of a study on the animals reactions to different sounds at Sydney's Taronga Zoo on Aug. 19. Mr. Westnedge, who is also the zoo's elephant keeper, plays his saxophone next to the underwater viewing window to assist the study by researchers from the Australian Marine Mammal Research Center. The seal occasionally responds with his own sounds, depending on the time of year, which are normally used when wanting to attract mates or establish territories.
