These snakes have upturned snouts that they use for digging, but their most peculiar trait is that they’re bluffers. When threatened, they flare their heads like a cobra and also strike – but those strikes are only head-butts. If this bluff doesn’t scare off a predator, these snakes will flop onto their backs and play dead. They’ll also let their tongues go slack and also emit a foul odor.
