This is the peacock mantis shrimp. It has the most complex vision systems known to science. They can see in 12 colours (humans see in only 3) and can distinguish between different forms of light to give a vivid 3D image. But these creatures are also totally badass... they have the ability to break out of aquariums by punching and smashing the glass with their claws. They have a punch stronger than a .22 calibre pistol. This is the fastest recorded punch of any living animal.
