Mantis shrimp live in the crevices of coral and rocks or in holes they make on the ocean floor. A territorial creature, it has been known to exhibit aggressive behavior toward intruders. This ferocious shrimp has hammer-like appendages that fold beneath its body, resembling a praying mantis.
With a spring-like motion, it uses these little hammers to attack prey and a mantis shrimp’s hit is NO joke. With the ability to strike at the speed of a .22 caliber bullet (50 times faster than the blink of an eye), a blow from a mantis shrimp can easily break through the shell of a crab or mollusk.youtube.com/watch?v=F5FEj9U-CJM
