The noise that this shrimp, which is just 3 to 5 centimeters long, makes inspired its name. It utilizes this claw, which is half the size of a shrimp, to eat and defend itself. In order to pursue its prey, the pistol shrimp closes its claw, causing a cavitation bubble that generates sonic pressures that can travel at up to 60 mph. If its larger claw is cut off, the smaller one grows up to take its place, and another small claw subsequently appears on the damaged stump. This deadly weapon has the ability to kill or stun fish and even crack shells.
Methods of Attack for Pistol Shrimp and Mantis Shrimp
Pistol shrimp are strong invertebrates that can produce tremendous underwater assaults using their claws. They cock their claws like a gun, then let forth a blast that stuns or kills their enemies by producing a cavitation bubble that creates a 200-decibel burst, temperatures that reach thousands of Kelvin, and a force that reaches 62 mph.
Mantis shrimp use their exceptional vision to hunt their prey. There are two types of them: spearing or crushing. The 51 mph spearing mantis shrimp attacks its food by stabbing it with its razor-sharp raptorial claws, causing cavitation. Its cavitation shockwave can kill its prey even if it misses.
Some mantis shrimp have a hardened “club” on their “arms” that unleashes a powerful smashing strike instead of using their raptorial legs as spears. In either case, their strikes swiftly overwhelm their prey.
Pistol shrimp claws’ Mechanism
The claws of the pistol shrimp snap together with such energy that a torrent of water is released, moving at a speed of about 71 mph (105 feet per second) towards its target. But when these bubbles break, the thunderous crack can be as loud as 218 dB. It also:
- lasting one billionth of a second, emits light.
- Temperatures in the bubble rise to around 4,800 degrees Celsius for a brief period of time (an amazing result from a two-centimeter length critter closing its claw!)
Your initial thought is presumably, “How can a little critter emit temperatures almost as high as the surface of the sun and noise louder than a pistol firing?”
The snapping claw of the pistol shrimp has a distinctive structure that provides the solution.
Water pours into a “socket” created as a pistol shrimp opens its claw. The plunger on the claw’s other half swiftly closes and expels water at a high rate of speed through tiny grooves.
What follows is a process called a cavitation bubble. Pressure suddenly lowers, which causes the nearby water to evaporate. Tiny bubbles expand as pressure decreases, and when pressure returns to normal, they abruptly burst with enormous energy.
When this bubble bursts, temperatures can rise to 4,800 degrees Celsius, a flash of light can be seen for as short as 10 nanoseconds, and a loud roar can be heard. Prey in the line of the shockwave caused by cavitation are stunned or even killed.
Pistol shrimp will repeatedly cock their claw back and fire at their target (pistol shrimp consume crabs, other shrimp, small fish, and other opportunistic foods).
The pistol shrimp uses its smaller pincer claw to bring its prey back to its lair after knocking it out cold.
Shrimp with a pistol
Imagine that only one arm of yours was used during your workout. Imagine you consumed so many protein drinks and lifted so much weight that your one arm became almost as big as your entire body, and you could clap so loudly that others around you actually died.
The arm of the pistol shrimp has a freaking cannon integrated into it. The shrimp chooses a covert location to hunt, such as a burrow, a piece of coral, or a small area of underwater grass, then waits while its antennae scan the water for prey.
The shrimp “loads” its claw by pulling the hammer back when something edible swims too close.
Then, with a loud bang, that claw clamps shut. The temperature of the fucking sun, or 5000 degrees Celsius, is briefly reached in the water in front of the shrimp. The vacuum in the water is collapsing with such intensity that there is even a flare of light.
The shockwave strikes the prey, killing or stubbing it. The shrimp may then drag them into its sniper nest where it can eat them whenever it wants.
They are also impossible to disarm. A pistol shrimp’s cannon arm will recover as a normal claw if it is lost, most likely to the ocean’s Jason Bourne. However, the other arm will grow enormously and turn into a cannon arm.
Pistol Shrimp can be found in freshwater caverns, temperate beaches, tropical waterways, and other locations all over the world. This year, an English fisherman discovered a pair of these crazy sniper shrimp off the coast of the UK. However, they are already traveling farther north than ever before, and it is hoped that fishermen wearing bomb-proof blast suits will catch them.
Climate change is the only answer, and while the shrimps themselves are okay with this, the fish and crustacean species already residing in their new shooting gallery aren’t. Any invasive predator is bad news, but one with such an unstoppable killing method is even worse.
Additionally, some of them—like bees, wasps, and ants—are even eusocial. A colony of the Synalpheus genus, which inhabits sea sponges, consists of a single “Queen” female, hundreds of workers, and hundreds of soldiers who are all equipped with the shockwave cannon of the pistol shrimp.

Mantis shrimps seem to have superhuman vision combined with explosive predatory arms, making them unbeatable. However, these animals are not worry-free. Mantis shrimps are able to kill fish, octopuses, and crabs in addition to other creatures. Additionally, they have the ability to murder one another. This brings up a significant issue. When the time comes, it’s time to start a family, but how can a mantis shrimp tell when another one it encounters wants to mate rather than launch a bloody attack?
Mantis shrimps were forced to develop strategies for determining when it was okay to go close and for indicating their own benign intent. For this, they also make use of their unique vision. Mantis shrimps frequently have vivid colors, and in polarized and ultraviolet light, they exhibit patterns that are unseen to our eyes. The intricate displays communicate their plans to other individuals of their species or those of other species. They can safely mate and give birth to a new generation of their species if their goals for the future include reproduction and the spectator shares their mentality.
So, yeah, sharks are safe. But do they make strikes like bullets? Possess they super vision? Can they kill prey in a matter of milliseconds? Mantis shrimps are the ones with these skills, and they employ them to develop into some of the most remarkable predators on the planet.
What can pistol shrimps obliterate?
Being referred to as a shrimp doesn’t exactly give you the reputation of being strong or frightening. The pistol shrimp, however, is a tiny, strange marine marvel that dramatically defies stereotypes. It is so potent that in addition to shooting and destroying its prey, it has also diverted the U.S. Navy’s attention, landed a superhero role on Netflix, and assisted researchers in their efforts to combat climate change. Snapping shrimp, sometimes known as pistol shrimp, gain its sea cred by producing bubbles, which appear innocent and infantile. These bubbles, however, are clearly not your typical bubbles; in fact, they produce enormous amounts of heat and a noise louder than a pistol.
These deadly bubbles are “shooted” by pistol shrimp to kill food, jackhammer into rock to dig tunnels, or defend those burrows from other, envious shrimp. As their one, gigantic snapper claw, which can expand to be half the size of their tiny body, is their gun, they don’t require a fancy holster or to stock up on ammunition.
Can a shrimp with a pistol stun a person?
When searching for food, it crawls behind rocks in reefs and uses its antennae. The Pistol shrimp stuns its prey by snapping its claw and making a loud noise. Faster than a speeding bullet, the bubbles struck. It then carries the meal back to the shrimp’s burrow where it gorges itself.
The snapping shrimp switches from its huge snapper claws to its tiny ones when in danger. With a lost limb, The Pink Floyd can still scare off predators! As a backup, this species possesses a smaller claw.
The little claw quickly grows larger than before. The Pistol shrimp can keep producing cavitating bubbles to suffocate unaware prey.
Additionally, they snap to communicate. Fun fact: The Pistol shrimp makes a mating call by flexing its big snapper claw. Humans may find the half-sized body and enormous front limb strange, but the female of the species does not.
Male Snapping shrimp are more seductive to females when they have a huge claw! Beauty truly depends on who is looking at it.
They cannot harm a human, to answer your query. This crustacean’s claw has no pincer at the tip. They can only irritate you by snapping loudly.
What consumes shrimp with pistols?
A unique claw on the Tiger Pistol Shrimp makes a loud clicking sound both when it is open and closed. If you pay great attention, you can hear this commotion even from outside the tank. This claw helps the Tiger Pistol Shrimp fend off predators and topple potential prey.
Pistol Shrimp and Shrimp Gobies from the genera Stonogobiops or Amblyeleotris frequently coexist in the same burrow. Yasha, Randall’s, Yellow Watchman, and Hi Fin Red Banded Gobies are suitable Shrimp Gobies. Under our gobies page and shrimp page, we have a number of shrimp/goby pairs for sale.
Tiger Pistol Shrimp may be eaten by triggerfish, larger hawkfish, groupers, lionfish, and huge predatory wrasses. With reef-safe fish, they do best.
Shrimp must have adequate pH, Ca, Alk, and Mg levels in order to grow. Iodine supplements will aid in the shrimp’s molting and growth.
Acclimation: Any shrimp should undergo a drip acclimation because they do not adapt well to abrupt changes in water chemistry.
It’s crucial to maintain the right levels of magnesium (1260–1350 ppm), calcium (420–440 ppm), and alkalinity (8–9.5 dkh; run it at 7-8 if you’re carbon-dosing). Algae outbreaks can be controlled by gradually raising magnesium levels up to 1400–1600 ppm; just be sure to maintain CA and Alk levels under control. Nitrate concentrations should be under 10 ppm and phosphate concentrations under 10 ppm. When nitrate concentrations reach 10 ppm, we advise doing a water change. When phosphate levels reach.10 ppm, it’s crucial to change your phosphate media. Your phosphate media is fluidized using media reactors to make the best use of it.
