'The Hero' contestants face down snakes - and math: Watch
During a team challenge in the Panamanian jungle, contestants Athena, Darnell and Shaun come face-to-face with what Shaun calls "an enormous vat" of snakes, as you can see in the photo at the top of the post and the video below -- both of which are exclusive to Zap2it.
They also notice a measuring tape in front of the box of reptiles. It quickly becomes clear that to complete the challenge, they have to measure several of the snakes. You can see how they do, and why Shaun calls Darnell "the beastmaster," in the clip.
"The Hero" airs at 8 p.m. ET Thursday on TNT.
