This week's podcast takes us to the beach at KwaZulu-Natal in South Africa, where Graeme Duane dips into a rock pool to look at sea urchins. Then Brad Bestelink in the Okavango Delta, Botswana, brings us action-packed highlights of a territorial clash between two prides of lion, and some confusion of identity in the chase. In Namibia, we take a look at the animal dynamics that occur at a waterhole in the spectacular Etosha National Park, brought to us by Linda Louw and Pierre Minnie. Lastly, Barry Skinstad swims with seals on South Africa's Western Cape coast to bring us footage of these streamlined creatures along with fish, anemones and kelp.
