Mantis shrimp can strike rapidly thanks to their powerful abdominal muscles that store elastic energy. When they release this energy, they propel their claw with colossal force, reaching speeds comparable to that of a bullet.
Mantis shrimp possess incredibly specialized raptorial appendages, which are like tightly coiled spring-like arms. They store their muscular energy in these limbs, just like one would draw a bow before shooting an arrow. When the accumulated tension is released in an instant, it results in a breathtaking strike, faster than the blink of an eye. The secret? Their hyper-resistant exoskeleton is made up of a structure that is both hard and flexible, capable of withstanding enormous acceleration without breaking. This unique structure combines rigid mineral layers with flexible organic layers, offering both strength and elasticity simultaneously. Another astonishing point: their independent, ultra-efficient eyes allow them to aim precisely at their prey or opponent, even at mind-boggling speeds.
The mantis shrimp has an articulated arm resembling a true biological spring. When it readies its strike, it slowly contracts extremely powerful muscles in this joint, temporarily locking in the energy accumulated thanks to structures called sclerae. As soon as it releases this mechanism, all that stored energy is unleashed at once. Like a bow suddenly releasing its arrow, the limb strikes at a staggering speed (over 80 km/h!) thanks to its unique musculoskeletal system. This evolved mechanism allows it to deliver violent impacts, comparable to projectiles.
The ultra-rapid strike of mantis shrimp is so powerful that it creates a surprising physical phenomenon called cavitation. Specifically, their extremely fast punch moves the water so quickly that it creates a bubble of vapor around their claw. Just after its formation, this bubble violently implodes, generating a small shockwave accompanied by a bright flash and intense heat. This implosion enhances the impact of the strike — it's like an "underwater double explosive effect." Some prey can even be stunned or killed just by the shockwave caused by this cavitation, without receiving a direct hit. Not bad for a shrimp!
Striking at high speed allows mantis shrimp to break the toughest shells, such as those of crabs or mollusks, in a fraction of a second. Feeding quickly while expending little energy is particularly useful when predators are lurking nearby. This lightning-fast strike also creates a shockwave that can stun their prey, even if they miss their target slightly. Finally, such speed is a serious advantage in defending their territory against rival mantis shrimp, much like the saying "whoever strikes the fastest holds the fort."
A mantis shrimp can strike at a speed of up to 80 km/h, as fast as a bullet fired from a small-caliber firearm. When it hits its prey, it generates an acceleration similar to that of a projectile fired from a handgun. Its front claw reaches the target in less than three milliseconds, which is about 50 times faster than a human blink. The impact releases an amount of energy comparable to that of a small-caliber bullet, allowing the mantis shrimp to easily break shells and exoskeletons.
The power of the mantis shrimp's strike is so intense that it can break the shells of marine snails, fish bones, and even aquarium glass.
Some species of mantis shrimp have one of the most advanced visions in the animal kingdom, with up to 16 photoreceptors, while humans only have three.
Some mantis shrimp use their raptorial legs not only to strike prey but also in competition for their territory or during courtship displays.
The extreme speed of the mantis shrimp's strike causes a phenomenon called cavitation, creating small explosive bubbles whose implosion generates heat and light.
Yes, scientists and engineers are studying the mantis shrimp's striking mechanism to design biomimetic devices, such as robotic arms or ultra-fast propulsion systems. These technologies could be useful in various industrial and medical fields.
The mantis shrimp indeed has one of the fastest strikes known in the animal kingdom, sometimes reaching speeds comparable to that of a small-caliber bullet. However, among terrestrial animals, some insects (such as Dracula ants or termites) also achieve extreme speeds with similar mechanisms.
No, mantis shrimps are divided into two main groups: the 'smashers', which use an extremely rapid strike to stun or kill their prey, and the 'spearers', which prefer to impale their prey with specialized appendages resembling harpoons.
Mantis shrimp got their name due to their physical resemblance to the terrestrial praying mantis. Both have powerful, folded forelimbs that they rapidly deploy to catch or strike their prey.
Yes, in some cases, mantis shrimp can strike hard enough to cause injuries to a human, especially during clumsy handling. Some species of mantis shrimp are even capable of cracking aquarium glass with their rapid strike.
