It takes enormous strength to charge through water. The lionesses of the Tsaro pride develop weight-lifter physiques by daily pursuing buffalo-their sole prey-through marshy terrain. Lions do not take naturally to water, but at Duba they've become swamp cats. Two other prides, each with a slightly different hunting style, share the 80-square-mile island, which shrinks by almost half in the wet season. But they aren't as bound to the herd as are the Tsaro lionesses, which can sleep in plain sight of the buffalo without causing alarm.
