I'm not surprised at all. Having seen - and heard - a pufferfish grinding an urchin in its mouth, there's no way I'd want my finger anywhere enard these guys' mouths. My fiance also tells a story of a pufferfish shooting out from under a ledge and attacking the divers on his charter. Everyone was minding their own business - my fiance is a gigantic hippy, and doesn't favor touching critters - but maybe they just caught the puffer on a bad day, I don't know. The puffer went straight for the exposed flesh on one of the diver's legs, between the wetsuit and bootie. My fiance herded everyone back to the boat, still being harassed by the puffer, who kept swooping toward the divers. The divers had to make their way from the tagline to the boat's ladder while keeping their hands out of the water, since the puffer wouldn't quit. They must have looked like a screwed-up version of the Village People, as the captain and my SO were calling, "OK, forward!" (Divers instinctively put hands in water to pull themselves along the tagline). "No, no, forward swim with your hands in the air! I want to see hands!" Even the captain's efforts to chivvy the puffer away from the divers with a spare freediving fin didn't work...this was one determined puffer. Fortunately, everyone got on board without incident, with the diver - a 12-year old kid - now the proud bearer of a weird puffer beak-mark on his calf . I've always followed a 'don't touch' policy around underwater critters, but after hearing my fiance and the boat captain relate the Incident of The Cantankerous Puffer, I give puffers a very wide berth!
