One of 10 melanistic grey seal pups (R) that have been spotted by rangers over the course of the winter pupping season 2020/21 in Blakeney Point, England. Black seals are rare with approximately one in 400 grey seals being melanistic. The rangers cannot tell if seals are grey or melanistic until they moult at two- to three-weeks-old and the black velvety coat is revealed. (Photo by Siebers/National Trust/PA Wire)
