Baltic Grey Seal Pup

The pups are born in winter, with a dense, soft silky white fur; at first they are small and shrivelled-looking, but they rapidly fatten up to look like over-filled barrels, from the extremely fat-rich milk they receive from their mothers. Within a month or so, they shed the pup fur and grow the dense waterproof adult fur, and soon leave for the sea to learn to fish for themselves.
