猪鼻蛇――自然界的一名丑角
The Hognose Snake，One of Nature's Clowns
The hognose snake，sometimes called the puff adder，is one of nature's clowns．Some people think that he is deadly poisonous．Actually，he's just a harmless fellow who spends most of his time huntingtoads．
The puff adder gets his name from being a terrific bluffer．He will swell up，hiss，and strike viciously to frighten you away．If that doesn't work，he will flatten out，making his head look like a cobra's．
He has one more trick――playing dead．He goes limp，opens his mouth wide，and rolls over on his back so that he couldn't possibly look more dead．
Unfortunately，this trick is spoiled by his one―track mind．If you pick him up he lies still．But turn him over and he will thrash about wildly，trying to turn himself belly up again．
