"Survivor: Worlds Apart": Meet the castaways

The 18 castaways competing on SURVIVOR this season, themed "Worlds Apart: White Collar vs. Blue Collar vs. No Collar."

CBS

"Survivor" is coming back for a milestone 30th season, and this time the competition has a new crop of castaways and a brand new theme.

Titled "Survivor: Worlds Apart," this installment will divide the 18 competitors into tribes based on their backgrounds -- White Collar vs. Blue Collar vs. No Collar.

The white collar tribe is made up of executives and other professionals who usually tend to make the rules, while the Blue Collar tribe has a postal worker, a state trooper and an oil driller - people known to follow the rules. And lastly, there's the No Collar tribe - a "YouTube sensation," a coconut vendor and other free spirits who tend to break the rules.

If this format sounds familiar, it's similar to the Brains vs. Beauty vs. Brawn concept used on "Survivor: Cagayan," which turned out to be one of the competition's best seasons to date.

"Survivor: Worlds Apart" premieres Wednesday, Feb. 28, with a special 90-minute episode beginning at 8 p.m. ET on CBS.
