You report "weird orange crocodiles" found gorging on bats in caves in Gabon (15 October, p 16). In the 1980s I worked with Partridge Films on a documentary for the BBC called Stolen River, about the drying-up of the Savuti river in Chobe National Park, Botswana, due to a tectonic shift, The crocodiles and hippos died out totally and the rest of the game migrated to the Linyanti river system.
