The 18 castaways have been split into three tribes: The "brawn" tribe includes former NBA all-star Cliff Robinson, the "brains" tribe has an average IQ of 130 and includes Miami Marlins president David Samson, and the "beauty" tribe features a pageant queen, a male model and a former NFL cheerleader.
