I swear Disney has used the Porcupine fish as a model for some of their characters.

Common Name: Porcupine fish


Latin NameDiodon Hystrix


Location: Florida, Bahamas, Caribbean, also Gulf of Mexico, north to Massachusetts, Bermuda and south to Brazil, circumtropical.


Distinct Features and Information: They are sometimes confused with puffer fish. Porcupine fish are closely related to puffer fishes but porcupine fish have heavier spines (hence the name porcupine) on their body. Also unlike the puffer fishes, they have only a single plate of fused teeth in each of the upper and lower jaws. Porcupine fish are medium to large sized fish and are found in shallow temperate and tropical seas worldwide. Porcupine fish have the ability to inflate their body by swallowing water or air, thereby becoming rounder. This increase in size (almost double vertically) reduces the range of potential predators to those with much bigger mouths. A second defense mechanism is provided by the sharp spines, which radiate outwards when the fish is inflated. Their favorite food includes crabs, sea urchins, snails and mollusks. Size: Up to a maximum of 35.4 in. (90 cm).
