Name 6 desert reptiles. Bet'cha said: tortoise, lizard, aah.. aahh. EXACTLY! It's amazing how many awesome reptiles we have in the Mojave Desert. Did you know we have one of the only truly venomous lizards in the WORLD living right here in the Mojave? Well it's true! The gila monster (pronounced "he-lah") needs to chew on its prey to inject its venom!
