http://en.wikipedia.org/wiki/Pufferfish "The 'porcupine', also called blowfish, swellfish, globefish, balloonfish are named for their ability to inflate themselves to two sometimes three times their normal size. Within inflating themselves large spikes shoot off of there scales. They do this by swallowing water when it is approched by a enemy. Or if the fish is taken out of water it well suck in air to inflate.; the same adaptation is found in the closely related pufferfish, which have small, almost sandpaper-like spikes."
http://biomechanics.bio.uci.edu/_html/nh_biomech/pufferfish/puffer.htm "When alarmed, some toads and snakes puff themselves up impressively. Hedgehogs, porcupines, and some Old World salamanders sport protective spines. But only the spiny puffer (Diodon holocanthus) combines inflation and pointy spikes in one spectacular defense mechanism."
