         Huge graves to be dug for whales stranded at New Zealand beach

Alison Joyce and her two-year-old son Tyler look at carcasses of long-finned pilot whales and bottle-nosed dolphins stranded on Sea Elephant Beach on Tasmania's King Island in Australia November 29, 2004. Over 100 of the mammals mysteriously beached themselves in a mass stranding which was repeated at another beach on the island states' south-east coast. More than three-quarters of Australia's whale strandings occur in Tasmania. (China Daily/Reuters)
