Eastern hognose snake
Other than its upturned snout, which is used for digging in sandy soil, this snake doesn't appear too strange — until threatened. Then it becomes the world's biggest drama queen. Capable of flattening its neck to resemble a cobra, it will strike, but the strikes are pure bluffs; it doesn't bite, it merely "head butts." If this strategy doesn't work to fend off threats, the snake rolls on its back and plays dead, going so far as to emit a foul musk and letting its tongue hang out of its mouth.
