McMahon's viper is a small, venomous snake that lives in the sandy deserts of Balochistan, near the borders of Iran, Pakistan and Afghanistan. It is well known for its habit of sinking into loose sand so that only its snout and eyes stay uncovered. Scientists have also studied a protein from its venom for its possible use against melanoma, a type of skin cancer.1
