Baykeeper Neil Blake talks about his brilliant new penguin-proof plant guards that support the nests of the resident penguins from the St Kilda penguin colony; the brilliant work of Brighton Sea Scouts, plus some coastal planting Neil is leading at Middle Park dunes. Then, Nicole Mertens from Victorian National Parks Association discusses the 14th Sea Slug Census, which has just started; and Dr Beach explains the cetacean retia mirabilia, or wondrous network, which researchers now believe protects the brains of whales and dolphins from the pressures brought about by swimming at depth. With presenters Bron, Dr. Beach, and Kade.
