Boa Snake gets its comeuppance after attacking a porcupine and getting pierced by sharp quills. <br />The wince-inducing footage appears to show a snake writhing in pain after being pierced with a porcupine's quills after attempting to eat it. <br />A video captures the Boa constrictor squirming as dozens of white quills protrude from its skin in Brazil. The impaled reptile had apparently attempted to eat the porcupine - but came off worse when the animal defended itself with its sharp quills. <br />The snake slithers and thrashes for almost two minutes, while a man records its pain. <br />Things got even worse for the reptile when the filmmaker's dog bounded over and started barking at it. <br />The wounded snake was forced to coil around to defend itself against the canine.
