Did you know that seal pups have a million hairs on every square inch of their bodies?

A grey seal pup weighs up to 20kg at birth.

A gray seal pup can look very serious when it is learning how to haul out on a rock.

When the seal pups were about ten days old, it was time for their first swim.

Then, even more astonishingly, this summer a young common seal pup was washed up on the beach.

The theme of my last film was based around that common seal pup washed up on the beach outside the house.

What I wasn't expecting was the responsibility of releasing a seal pup.

More than forty grey seal pups are rescued each year.

In the 1950s and 1960s an average of over 291,000 seal pups were killed each year.

In 2002 and 2004 to 2006, over 300,000 seal pups were killed each year.
