Survivor: One World is the 24th season of the American CBS competitive reality television series Survivor, featuring 18 new castaways divided by gender into two tribes of nine. The cast is composed of 18 new players, initially divided into two tribes by gender: the 9 men composed Manono while the 9 women composed Salani. Notable cast members include Leif Manson, the first little person to compete on Survivor, and Monica Culpepper, wife of former NFL football player Brad Culpepper. The 18 castaways were divided into gender-based tribes and given maps to their camps, unaware they would lead to the same location. Despite living on the same beach, the tribes would remain split, building separate shelters and fending for their own tribe. As a result of the shared campsite, hidden immunity idols were designated for specific tribes; if a castaway found the idol designated for the opposing tribe, he or she was required to give it to a member of the other tribe before the next Tribal Council.
