Grey Seal Halichoerus grypus

Grey Seals, spelled Gray Seal in the US and also called Atlantic Seals, are resident around the coasts of the north Atlantic (including Baltic and North Seas).

Grey Seals have a cone-shaped, aerodynamic head, unlike the dropped forehead and dog-like muzzle of the Harbour/Common Seal (see link below). The Grey Seal is also significantly larger (especially males). More difficult to see are the wider-spaced, parallel nostrils rather than the slight "V" or heart-shape of the Common Seal. True seals have claws at the end of their front feet ("arms"), unlike fur seals and sealions, and they can't raise themselves up on their flippers so are more cumbersome on land.

Sealy joke: "What did the seal say when it swam into a wall?"  "Dam."
