Pufferfish belongs to the family of Tetraodontidae, the majority of pufferfish species are toxic and some are among the most poisonous vertebrates in the world.
When a pufferfish feels intimidated, it will fill its extremely elastic stomach with water (or air when outside the water) until it is much larger and almost spherical in shape, in order to scare away the enemies.
The camouflages of these fiches are excellent, you can't barely see them even if you get close.
