Not you're average looking fish, the puffer fish is known for it's ability to undergo a complete body transformation in seconds. In fact, they're so unique that there's around 120 different species of Puffer Fish that mostly reside in the tropical waters of the Indian, Atlantic and Pacific Ocean. Despite their somewhat intimidating shape their size is extremely changeable - from one inch to two feet, all in an effort to scare their predators.
Stay away from them though, as they contain a toxin 1200 times stronger than cyanide, which is enough to kill 30 adult men! Despite the toxin, in Japan, some parts of the fish area actually a delicacy, although you have to be specially trained to prepare it otherwise you might end up killing someone! But of course the toxin does out predators off them, the only species that's immune to the fish is a shark, so in many ways they're quite safe in the oceans!
They also have a body perfectly adapted for a life at sea for example, they have four teeth, fused in a beak like structure ideal for opening mussels, clams and other shellfish. They've also got excellent eyesight so they can spot predators from afar. All in all they're pretty amazing fish, but I'd stay away if I was you!
