Puffers "puff" by inflating themselves with water. This is why they should never be picked up or taken out of the water. If they inflate air instead of water they have a very difficult time uninflating and could die.

Elena Puff (Mrs. Puff) is a "Puffer Fish" .
I know that puffer fish just are scared so they puff up to scare other fish away!But they are vegetarians and like to eat seaweed!
A puffer fish moves like any other fish. They swim through the water and puff up when they feel that they need to be defensive. They have tiny fins.
The average weight of an adult puffer fish is 10 to 30 pounds. They weigh more when they puff up because they quickly ingest water.
When the puffer fish inflates its body to increase its size it is a behavior called a defense mechanism. Puffer fish have highly elastic stomachs and the ability to quickly take in air or water to puff themselves up. This turns them into an inedible ball.
they puff up like a ball with spikes. It looks something like sea urchin when it puffs up.
The formal species name for the puffer fish is Tetraodontidae. It's in the Animalia kingdom, Chordata phylum, Vertebrata subphylum, Actinopterygii class, Neopterygii subclass, Teleostei infraclass, and Tetraodontiformes order.
Puffer fish have spines and a rib cage so they are most defiantly vertebrate
puffer fish originated from humans an there are few human / puffer fish left . I have met one myself and it was one of the most exhilarating experiences of my life .Watch out because they can still puff .
