 Scientists in New Zealand say a whale which was found dead on a beach in Otago province earlier this month is believed to be a spade-toothed whale, a species so rare it's never been seen alive. The five-metre-long beaked creature was identified from its colour patterns and the shape of its skull, beak and teeth. Its remains have been placed in cold storage while DNA testing takes place, with experts saying it may take several weeks before a final identification is confirmed.
