Eastern Smooth Boxfish
The Eastern Smooth Boxfish is very, very smooth. If you look at one closely, they look like they are covered in velvet. The 'box' description isn't too bad either.
You wouldn't have thought that a small, bright yellow fish, that can't swim too well would survive long underwater... but you'd be wrong. They have virtually no predators. This is because they are filled with the same toxin that's in a pufferfish. It's enough to kill virtually anything silly enough to eat one.
