Mantis Shrimp

A crustacean that punches with the force of a bullet/Marine Life

The peacock mantis shrimp (Odontodactylus scyllarus) is one of the most remarkable predators in the ocean. At about 18 cm long, its spring-loaded club appendages strike with an acceleration of over 10,000 g, reaching speeds of about 23 m/s underwater. The impact generates cavitation bubbles that create a secondary shockwave, effectively hitting prey twice with a single punch. They also have the most complex eyes in the animal kingdom, with 16 types of photoreceptors compared to our three.
