Strongest "punch" in the world.

     Mantis shrimp or stomatopods are marine crustaceans, they are neither shrimp nor mantis, but receive their name purely from the physical resemblance to both the terrestrial praying mantis and the shrimp.  These aggressive and typically solitary sea creatures spend most of their time hiding in rock formations or burrowing intricate passageways in the sea-bed.They are burrowers, constructing U-shaped holes in the loose substrate near the bases of coral reefs in water ranging from 3 to 40 meters (9.8 to 130 ft) deep. Mantis shrimp is a smasher, with club shaped raptorial appendages. An active hunter, it prefers gastropods, crustaceans, and bivalves, and will repeatedly smash its prey until it can gain access to the soft tissue for consumption. It is reported to have a "punch" of over 50mph. The fastest punch of any living animal.They are active, intelligent, curious animals, capable of interacting with their keepers. Although it happens rarely, some larger species of mantis shrimp are capable of breaking through aquarium  glass with a single strike from this weapon. The eyes of mantis shrimp may make them able to recognize different types of coral, prey species (which are often transparent or semi-transparent), or predators, such as barracuda, which have shimmering scales. In a lifetime, they can have as many as 20 or 30 breeding episodes. Depending on the species, the eggs can be laid and kept in a burrow, or carried around under the female's tail until they hatch.
