This creature has the oddest eyes in the animal kingdom

Mantis shrimps throw the fastest punches in the ocean. Using their forelimbs like clubs, the small crustaceans deliver blows so quickly and forcefully that pockets of seawater vaporize in implosions of light and heat. The shrimps leave ruin in their wake, cracking into snail shells, panes of aquarium glass and human thumbs. Of the more than 450 species of mantis shrimp (distant relatives of the kind that hang around cocktail glasses), one of the best-studied species is the peacock mantis shrimp, Odontodactylus scyllarus.
