Seals

Dr Simon Gibbon believes pollution disturbed by dredging is responsible for seal pup deaths.

A marine charity is urging beachgoers to keep dogs on a lead and observe seals from a distance.

Frosty, Glacier and Avalanche are said to have done "incredibly well" in their recovery.

Marine investigators say the death may be linked to a group of grey seals operating between Wales and Devon.

The pup, believed to be a couple of months old, was taken to the vets to receive urgent treatment.

The young grey seal was found "fighting for its life" at Gyllyngvase Beach.

The pup, thought to be about five or six months old, got stuck in the garden after leaving rough seas.
