This Sunday’s episode of the Discovery Channel’s survival reality show Naked and Afraid will find one contestant in a self-described epic battle with a lizard he intends on eating in order to survive.

“I’ve already burnt more calories than I’m gonna get from eating the guy, but I don’t like this lizard,” Jeff says as he works tirelessly to dig the lizard out of its hiding spot in the harsh Madagascar heat. When Jeff finally wriggles the lizard free, he is so excited that he bites its head off right then and there.

Watch the intense clip from Sunday night’s episode below:

Each episode, the Discovery Channel series strands two complete strangers of the opposite gender in a remote area of the world with harsh weather conditions with no food, water, or clothing. Together, the duo must survive 21 days on their own with nothing but one helpful item of their choice, all for the glory of knowing they scored well on the show’s Primitive Survival Rating.

Catch the latest episode of Naked and Afraid on Sunday at 9 p.m. on the Discovery Channel.
