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."
