Happy pup - Grey seal (halichoerus grypus)
Grey seal (halichoerus grypus) pup looking to be giggling as he is playing around chewing his flippers. Seal pups spend much of the day sleeping on the sand or playing about, and because of the curvature of their mouths, they seem to be smiling all the time. Donna Nook, UK.
