"Beautiful" and "deadly" are two descriptors you don’t typically see attached to shrimp. But the mantis shrimp is in a class of its own. This colorful specimen has earned a reputation for being one of the most fearsome creatures of the deep. This can smash any hard shell easily using its front legs. Smashers have club-like appendages that easily smash shell of snails, oysters, crustaceans and mollusks.
 
This fascinating video footage shows a giant mantis shrimp attacks crabs with blinding speed and dismembers them with the force of its blow. The shrimp attack the crab and starts to hit it on the under part of the crab with a great speed using its punch of the powerful front legs. Attack of mantis shrimps happens extremely quickly - 50 times faster than the blink of an eye. With velocity of 10 meters per second, their punch has the power of a .22 caliber bullet.

This is actually a terrifying face of a sea creature. Don't forget to share this  video with your friends and on Facebook.
