Dive in amongst the pinnipeds - the seals, walrus and sea lions - for a taste of what life is like for fin-footed, semi-aquatic mammals. Flat flippers help give these typically rotund, barrel-shaped animals an unlikely grace and beauty underwater and also help them move around - though with somewhat less grace! - on land. Explore via the image links below to find information and video clips about the individual species from the Autumnwatch favourite, the grey seal, to the mighty walrus in extraordinary footage from Planet Earth showing a polar bear attack - a fearsome clash of Titans.
