A seal woke to the sound of jazz music yesterday morning (July 4) at Taronga Zoo in Sydney.

Elephant keeper Steve serenaded leopard seal Casey with a saxophone, as part of a scheme to keep him stimulated and to study how he reacts to different sounds.

Marine Mammals Supervisor Ryan Tate explained that leopard seals sing to attract mates and possibly to establish territories, and added that Casey sometimes sings back to the music, depending on the time of year.

"At certain times of year they really react to the noises and sing back," he said. "They are certainly aware of new noises, so something like the saxophone was a great way of giving our leopard seal some different environmental enrichment.

"Ranging from some very high-pitched sounds to a wide variety of music, we think Casey was having a good time with Steve and his saxophone."

London Zoo recently got pianist Richard Clayderman to perform a set of ballads to encourage Galapagos tortoises to mate.
