Creature of the day:  Porcupinefish

Yesterday we went swimming in a rainstorm- very nice underwater.  We watched one of these guys for a while- his size made him easy to follow.  He went pretty deep, below where we could see him, and then came up to shallower water, turning around to show all possible angles.  We didn't scare him- when frightened, they blow themselves up into a spiky ball.  Very cute fish- pug lovers would find him irresistible.
