Spot-Fin Porcupinefish

The Spot-Fin Porcupinefish (Diodon hystrix) is also known as the Black-Spotted, Spotted Porcupinefish, Blowfish, Spiny Box Puffer, Hedgehogfish and Swelltoad. It should not to be mistaken with the Black-Spotted Pufferfish, which is a completely different species that doesn't have spines.

This Porcupinefish is normally 50-60cm in length but can grow to 90cm in some cases. Like Pufferfishes, the porcupinefish can inflate its body when it feels threatened. It lives in tropical and sub-tropical seas around the world, usually feeding on gastropods, crustaceans and sea urchins at night. They have a good range of vision from being able to move their large eyes independently, but it's quite common to see individuals with damaged or missing eyes from past incidents.
