Survivor: One World Cast Revealed: Battle of the Sexes, Beach Party Edition!

CBS' veteran reality show's 24th season features 18 brand-new Castaways in two tribes divided by gender but sharing the same camp

On Survivor: One World, the war begins at home.

For the first time, Survivor will launch a season—its 24th—with two opposing tribes living together at the same camp.

Telling the two tribes apart will be easy: the 18 Castaways—nine men and nine women—are split evenly by gender. (This division was first used in The Amazon, the reality show's sixth season.)

Will this battle of the sexes include any familiar faces?

You might recognize a few model-actor types, but no returning Survivor players will be competing this season. The very pretty cast also includes the reality competition's first little person, 34-year-old actor Leif Manson.

Season 24 is also dispensing with the controversial Redemption Island twist, devised to give returning vets—and easy targets—like Boston Rob Mariano and Ozzy Lusth a second chance (and more screen time). When host Jeff Probst snuffs a castoff's torch at Tribal Council, they will gone for good.

The most intriguing question of season 24 is how the One World alliances will form. Will the players make early deals with members of their opposing tribes? Or will the two tribes stick together? Will the tribes share resources at camp, or can we anticipate another Redemption Island rice war?

There's one more potential threat to tribal allegiances: romance. Survivor is famous for hookups between castmates like Rob and Amber, Ozzy and Amanda and last season's Whitney and Keith.

We'll find out when Survivor: One World returns to its Wednesday-night time slot Feb. 15. Meanwhile, here are the members of the Salani and Manono tribes—named after regions in Samoa, where, like seasons 19, 20 and 23, One World was filmed.
