1. Black Fawn Deer:
Why is this fawn black? It’s due to a rare genetic color variation that is even more uncommon than albinism known as melanistic. Essentially, their bodies produce a surplus of melanin in their hair, skin, and retina pigment.
North American Whitetail considers this to be “the rarest of the rare. While millions of whitetails have been harvested across the continent in modern times, only a token number of cases of melanism have been documented.”
2. Black Seal:
Black Seal belongs to a diverse group of semi-aquatic marine mammals, many of which are commonly called seals.
