East Africa is a land which is constantly changing. To survive here, creatures must be able to deal with unpredictable twists and turns û wet turning to dry, famine to feast, cold to hot û no matter how hostile and unpredictable it becomes. From dense forests, to snowcapped peaks, steamy swamps to endless savannah, this unique and varied land is also a haven for life û it supports a higher density of large mammals than anywhere else on Earth. But away from the forever-travelling herds, there are a huge cast of other characters û lizards that steal flies from the faces of lions, vast dinosaur-like birds who stalk catfish through huge wetlands, and elephants who battle for three days for the right to father the next generation. East Africa can be a cruel and unforgiving place, when the stakes are high you must be prepared to take risks and if necessary to gamble with your life.
