Harlequin Mantis Shrimp~ The mantis shrimp has one of the most elaborate visual systems ever discovered. It moves so quickly that the water around it boils (this is called supercavitation). They also pack a serious punch that sends out shock waves through the water. These shock waves have been known to shatter aquarium glass. by rinjani
Mantis Shrimp . Probably the best eyesight in the entire animal kingdom. Each of the eyes has three visual centers, making them the only animal in the world to have trinocular vision...even if they close one eye. Interesting info at this site.
