Melanistic Grey Seal Pup

Grey Seals are one out of two seal subspecies, which are native to the UK. This seal subspecies is born in a white non-waterproof fur coat, and will moult into the first adult fur coat after mum leaves them (when they will be 17-23 days of age).
This pup is moulting into the first adult fur coat, which appears to be black in this case (the pup has a recessive gene and hence too many dark pigments).
