Dominic is in Arizona’s Sonoran Desert, the most bio desert in all of North America – it’s also one of the hottest. He’s come here to explore more than a hundred thousand square miles of wild desert, on a mission to find one of America’s most mythic creatures, the Gila Monster. It’s the largest of its kind in North America – a gorgeous ground dwelling creature that packs one of only two venomous lizard bites in the whole world! On his trip around the desert, Dominic runs into other fascinating and dangerous creatures including the biggest species of rattlesnake in North America and a Black Widow Spider.
