The Katuma river is the lifeline of Katavi National Park supporting a vast population of hippo and crocs through the dry season. As the river dries into a series of pools crocs indulge in their annual feast of cat fish and you will find them no where bigger! Crocodiles can survive on one meal a month and during extreme conditions where food becomes scarce, or they are unable to regulate their body temperature, they dig caves and aestivate for months until better conditions arrive. There is no where better to see this behaviour than in the Katuma river where the caves are exposed during the dry and where they have probably been for 200m years! Since they are unable to chew Crocs also use caves to store prey under water until tender enough to tear apart.Allow blocked content for browser to download slideshow.
