This is not a melanistic whale, instead it is a beluga whale, which is usually white. Filmed in January it is only the sixth time that this species has been sighted in Scottish waters, generally living in the icy arctic waters.
This species has around 150,000 individuals left in the wild, making them more safe than many species. However, living in the Arctic where global warming is changing things fast, we need to remain viligant, as it could be quite a different situation after not much time.
