About

The grey seal is the larger of the two UK seal species. If you catch a good look at them you’ll see how they got their scientific name, Halichoerus grypus – it means hook-nosed sea pig! These mammals spend most of their time out at sea feeding on fish. They return to land to rest and can often be seen ‘hauled out’, lying on beaches. Grey seals give birth to fluffy white pups in the autumn and winter. These adorable pups stay on land until they have lost their white coats and trebled their body weight.

How to identify

The grey seal can be distinguished from the common seal by its larger size and longer head with a sloping 'roman nose' profile. Looking straight on, their nostrils are parallel, rather than v-shaped as in common seals. Mainly grey in colour, the unique pattern of darker blotches and spots can be used to identify individuals.

Distribution

Found all around the UK.

Did you know?

Despite numbers dropping to only 500 in the early 20th century, it's estimated that there are now more than 120,000 grey seals in Britain, representing 40% of the world's population and 95% of the European population.
