Strongest self-powered strike by an animal

The peacock mantis shrimp (Odontodactylus scyllarus), a species of stomatopod, flails its club-shaped front leg at peak speeds of 23 m/sec (75 ft/sec) to shatter the shells of its prey. The force of the blow is over a hundred times the mantis shrimp’s body weight (that body weight being up to 0.6 kg, 1.35 lb). Stomatopods also have the sophisticated eyes of any animal on Earth – some species have more than 10 pigments sensitive to different wavelengths of light, compared to only three pigments in humans.
