The water is then forced out of the chamber when it clamps down due to pressure from a little plunger on the top claw. Bubbles are produced as a result of the speed of this. And not just any bubbles—these bubbles have a top speed of 60 mph, which is swift enough to kill or stun the target!
The shrimp releases an air bubble at its target at a speed of more than 100 kilometers per hour (62 mph) by rapidly shutting the claw.
The shrimp’s top claw opens to let water flow into a small chamber in its crook, which begins the action of this water gun. The water is then launched by the little plunger on the top claw as it clamps down with remarkable force. This expulsion causes a loud popping sound and a potent bubble that is lethal to the shrimp’s prey. The snap sound lasts for a very brief fraction of a second, yet it measures at roughly 218 decibels, making it louder than a gunshot. In truth, considerably larger animals like sperm whales and the tiny pistol shrimp contend for the distinction of “the loudest animal in the sea.”
The shrimp also produce a tremendous amount of force and heat. Up to 8,000 degrees Fahrenheit (4,427 degrees Celsius) of heat are released when the bubble bursts, making it four times hotter than lava. Only the poor little thing that the shrimp was aiming at is affected by the heat, which swiftly fades.
Even if the shockwave is minor and the damage it does is localized, the hit is nonetheless incredibly amazing. In reality, the pistol shrimp is among the most powerful animals that have ever lived, pound for pound.
Creating such a remarkable adaption is difficult. According to recent studies, the pistol shrimp actually underwent over 100 million years of evolution to get its current super-claw.
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.
So, how exactly loud are the shrill cries of the Pistol or Snapping Shrimp produced? The 1.5–2 inch long shrimp possesses a single, enormous snapper claw with a pistol-like characteristic rather as the more common pinchers. The shrimp launches a bubble bullet at up to 62 miles per hour, producing a 218 dB shock wave as the bubble explodes, by cocking one side of the claw and snapping it into the other side quickly. The shrimp’s victim is stunned by the sonic shock wave.
Sonoluminescence, which is the brief emission of light from bubbles implosion in a liquid triggered by sound, is created as the bubble breaks. The temperature of this discharge is 8,000 degrees Fahrenheit. In contrast, the surface temperature of the sun is thought to range from 7,300 to 9,950 degrees Fahrenheit. Weaponized bubble bullets that are nearly as hot as the sun’s surface sound extremely deadly.
When hunting or interacting with one another, these underwater gangsters are anything but cautious when it comes to firing their weapons. Large populations of the shrimp have been known to make such a racket that the sound will reverberate inside of canoes and other watercraft, keeping sailors awake at night. The sonic noise can get so bad that it even interferes with sonar technology. In order to acoustically conceal their warships from sonar equipment, the US Navy really stationed their submarines in colonies of Pistol Shrimp and played Pistol Shrimp snapping sounds from underwater speakers during World War II!
In temperate coastal waters, you can find pistol shrimp on coral reefs, underwater seagrass flats, and oyster reefs. There are many colonies of the trigger-happy shrimp on Sanibel Island’s J.N. Ding Darling National Wildlife Refuge. They typically hunt well below the surface of the water where people are fishing. If you’re close to the water, keep an ear out for the fizzing or crackling sound of their gunfire to catch a glimpse of a sharpshooting match the size of a shrimp!
How potent is the shrimp pistol?
The pistol shrimp, which resembles a technicolor lobster, gets its name from its main method of attack: a claw that shoots bubble “bullets.” The shrimp can exert enormous power at a speed of more than 100 feet per second by building up enough pressure inside its jaws. (This “bullet,” or the snap of the bubble collapsing, actually makes a sound that is 60 decibels louder than a genuine gunshot.) The shrimp kills its prey with the use of a shockwave, which it then drags into its residence to eat.

In fact, the shockwave’s velocity is high enough to evaporate nearby water. Additionally, 8,000 degrees and a bright flash can be produced momentarily. (The shrimp also drill into basalt rock to form a burrow using their blaster powers like a jackhammer.) The shrimp’s cannon arm can truly grow back if it is injured.
However, pistol shrimp may coexist harmoniously with a number of other species and are generally amiable.
And they are actually tiny guys—about 4 centimeters long (and 25 grams). They could easily kill small fish with their snap, but we’re not sure if they could “tear flesh from bone” of anything too huge.
However, even though the shockwave and damage are very minor, the pistol shrimp is still one of the most potent organisms in existence, weight for weight. Imagine the same strength in a human, which is 4,000 times bigger than a shrimp.
At 97 km/h, pistol shrimps snap.
Pistol Shrimps must be swift to live in the wild due to their small size.
The speed of a Tiger Pistol Shrimp is 97 km/h (60 m/h).
A Without a slow-motion camera, humans cannot observe the snap. To see that the propus and dactyl do not fully touch, scientists had to utilize an ultra-high definition camera that captured 40,000 frames per second.
The fastest animal is the pistol shrimp, right?
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.
How loud are shrimp pistols?
Loud bubbles are present. extremely loud. One recently found species of pistol shrimp with the name Synalpheus pinkfloydi (after another loud and wonderful thing: Pink Floyd) has a snap that can reach 210 dB. That is louder than a gunshot, which typically registers between 140 and 175 decibels.
What if you get shot by a shrimp pistol?
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.
