Though neither the biggest nor the fastest animal on earth, the mantis shrimp is one of Mother Nature’s most exquisite creations, a perfect specimen of the harmonisation between physics and nature. It is amongst the smaller marine creatures in the marine ecosystem, no longer than 30 cm in length, but its abilities demonstrate several interesting physics phenomena and have inspired numerous technologies as well. To this end, two features of the mantis shrimp merit special attention: its rapid punch and its extraordinary vision. Not a Shrimp? Mantis shrimps are marine crustaceans of order Stomatopoda. Ironically, mantis shrimps are not actually shrimps but are named as such due to their similarity in appearance to shrimps and the land-dwelling praying mantis. Mantis shrimps inhabit the shores of shallow tropical or subtropical waters and usually live in uninhibited burrows, coral reefs or rock crevices. They spend the majority of their lives in their burrows, and only come out to hunt for food, which includes clams, fish and other small invertebrates . There are two kinds of mantis shrimps: “spearers” and “smashers”. “Spearer” mantis shrimps use spiny barbed claws to stab their prey while “smasher” mantis shrimps have distinct modified claws, known as raptorial appendages that they use to break the shells of other crustaceans for food . Figure 1: The peacock mantis shrimp Odontodactylus scyllarus, is an example of a “smasher” mantis shrimp.  Animalia Brus Lee One such “smasher” is the peacock mantis shrimp Odontodactylus scyllarus, shown in figure 1. Researchers have studied them extensively and have found out that they can deliver strikes of up to 1500 N that last only a few milliseconds. Such punches can reach speeds of over 20 m s-1 and astonishing accelerations of over 105 m s-2, equivalent to that of a .22 calibre bullet . This makes it the bearer of the world’s fastest punch, and also warrants the moniker “Bruce Lee of the animal kingdom”. Figure 2: Two force peaks observed for a single punch exerted by the mantis shrimp.  Researchers also found that, surprisingly, a single strike generates two significant short, high-amplitude force peaks, typically 390-480 μs apart , as shown in figure 2. While the first peak is certainly due to the impact of the punch, some unapparent occurrence gives rise to the second peak. Spooky Bubbles With the aid of high-speed cameras, researchers discovered that tiny bubbles are formed when a mantis shrimp delivers a blow, as seen in figure 3. These bubbles, known as cavitation bubbles, arise due to the rapid acceleration of the mantis shrimp’s appendage, which leaves behind a region of low pressure between the appendage and the surface it strikes. Figure 3 : Pictures of the mantis shrimp’s punch captured using a high-speed camera. Cavitation bubbles are observed between its club and the surface it is striking. The formation of the bubble can be explained using the Clausius-Clapeyron relation , dP/dT=L/TΔv , (1)>GET ANSWER
