Shrimp have never been known as powerful creatures, but the Peacock Mantis Shrimp is not an animal that you want to mess with. (And, for the record, the Peacock Mantis Shrimp is technically a crustacean.)
This colorful little guy has two fist-like limbs called "dactyl clubs," and he can punch aquarium glass hard enough to shatter it without injuring himself at all! In addition to being an awesome skill, the chemical makeup of the Peacock Mantis Shrimp's dactyl clubs may have some scientific significance for future architecture and material synthesis. (The main ingredients in the fists of the Peacock Mantis Shrimp are chitin and some crystallized calcium phosphate).
The Peacock Mantis Shrimp can "punch" at a speed of over 50 miles per hour and uses its strength to break the shells of mollusks.
Aquarium owners, in addition to experiencing glass broken by the Peacock Mantis Shrimp, have complained about its aggressiveness and its tendency to eat the other aquarium members.
The bottom line? The Peacock Mantis Shrimp is awesome, but leave it in the Indo-Pacific where it belongs.
