The peacock mantis shrimp (Odontodactylus scyllarus) is recognized as having the fastest punch in the entire animal kingdom, with an acceleration comparable to a .22mm bullet fired out of a handgun.
One of several known mantis shrimp species, the O. Scyllarus is native to the seabed of the Indo-Pacific, from Guam to South Africa. It is an agile and active predator, using its club-shaped appendages to smash its prey, which mainly consists of other crustaceans, gastropods, and bivalves. The peacock mantis shrimp is known as a ‘smasher’ for a reason, as it uses its appendages to repeatedly deliver blunt force to its victims until it breaks their exoskeletons in order to reach the soft tissue underneath. Every blow travels at a speed of over 50 miles per hour (80 km/h), the fastest recorded punch of any living animal.
