Porcupinefish

Not to be confused with its smaller cousin, the pufferfish, you can distinguish porcupinefish by their elongated bodies and large eyes. There are several species of porcupinefish within the Diodontidae family, all of which can inflate their bodies when provoked or threatened. They activate this unique defense mechanism by swallowing water or air to increase their size and cause the sharp spines covering their bodies to stand on end.
