A fearsome predator. As big as a bear, the jaws of a wolf in contrast to the captivating eyes and beguiling nature. The grey seal lives for most of its life beneath the surface of the water, hidden from us humans. Thats where it eats sleeps and hunts, its streamlined body gliding effortlessly through the water. But do we really know the grey seal? In The Secret Universe of Seals we are taken deep into the world of the seal. We are there when its born, when the fluffy white pup sheds its baby fur and has its first swimming lesson. We are with the mother when the males fight and compete for her attentions. Most importantly we follow the seal underwater into its hidden domain.
