Kiss me quick… A newborn harp seal has a thick white fur coat for camouflage on the Arctic ice. The pup can’t join its mother on fishing trips until its adult coat grows in, so it depends on her high-fat milk. Once it’s weaned the pup will have to wait four weeks until its waterproof fur has grown – and during that time it will lose half its body weight
