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).
I have observed at Blakeney Point and also at Horsey Gap (photo), grey seal pups in their first adult fur coats still interacting with or even feeding of mature grey seal cows (presumably their mums).
