“Willow the white whale has been causing a splash – after being spotted swimming in a pod of whales. Dan Fisher, 32, was on a boat trip to Svalbard in Norway when he noticed a giant white hump rise from the water. Rushing up a mast to get a better look, he quickly realised he was witnessing one of natures rarest sights – a white whale. Its colour is caused by a condition called Leucism, caused by a reduction in all types of skin pigment.”
