Like a scene from Moby Dick, a rare white whale was spotted off the coast of Spitsbergen in Norway by maritime engineer Dan Fisher of the UK. Swimming alongside a pod of other, regular grey humpback whales, this whale likely has a condition called leucism, which causes a reduction in skin pigmentation. Animals with this condition rarely survive long in the wild, because they lack their natural disguise and can more easily be picked off by predators, however the white whale, now named Willow, appears to be an adult fully incorporated into a pod.
