Puffer Fish Releasing Water Is Really Satisfying To Watch

A video of a pufferfish deflating has gone viral, largely because it's really, really cool to watch, but also because everyone seems to have the same misconception about these wonderful fish.

These strange creatures can inflate themselves to be impressively large when threatened, almost doubling their original size. This makes them much more difficult to eat, especially in species that have sharp spines that show through the skin when they are inflated.
