When not at sea, common seals are found around sheltered shores and estuaries, where they haul out on sandbanks and beaches. When out of the water, they sometimes hold their body in a curved banana position, with their head and tail both in the air at the same time. Like grey seals, they feed on fish, but also eat squid, whelks, crabs and mussels. Common seal pups are born during the summer and can swim when they are only a few hours old!

The common seal can be distinguished from the grey seal by its smaller size and shorter head with a more concave forehead. Common seals have V-shaped nostrils. They are very variable in colour, from blonde to black, but generally grey with dark spots.
