Somewhere at the bottom of the ocean, there is a small creature about the size of your hand. It has bright colors like someone spilled a whole box of crayons on it. It walks around like it owns the sea floor.
And if you make the mistake of messing with it, it will punch you so hard that the water around its fist literally boils.
That creature is the mantis shrimp. And honestly, it might be the most terrifying thing alive.
Wait, Is It a Mantis or a Shrimp?
Neither, actually.
The mantis shrimp is not a real shrimp. It is not a mantis either. Scientists call it a stomatopod, which is just a fancy word that means “mouth foot.” That name makes no sense, but at this point, nothing about this animal makes sense, so let us keep going.
It got the name “mantis shrimp” because its front legs look like the legs of a praying mantis.
So basically, someone looked at this creature and said, “It kind of looks like two things, so let us name it after both of them and call it a day.” Scientists were apparently very tired that day.
The Punch That Should Not Be Possible
Here is where things get crazy.
The mantis shrimp has two front clubs, and it uses them to punch things. Not just regular punching either. It punches with the speed of a bullet.
Its clubs move at about 23 meters per second, which is roughly the same speed as a .22 caliber bullet leaving a gun.
Now, you might be thinking, “Okay but it is a tiny animal. How much damage can it really do?”
It can break aquarium glass.
Yes. Actual glass. Scientists have had to build special tanks just to hold mantis shrimps because these little creatures will shatter a regular aquarium like it owes them money.
There is also a bonus punch that happens that is honestly unfair. When the mantis shrimp strikes, it moves so fast that it creates tiny bubbles in the water around its fist. Those bubbles then collapse and release a second shockwave of energy.
So the prey gets hit once by the actual punch, and then hit again by the ghost of the punch.
The mantis shrimp is out here throwing two punches with one arm. That is not fighting. That is showing off.
16 Types of Color Receptors in Its Eyes
Humans have three types of color receptors in their eyes. Three. And we already think we see a lot of colors.
The mantis shrimp has sixteen.
Sixteen types of color receptors. To put that in perspective, imagine you are watching a sunset and you see orange, pink, and purple. The mantis shrimp is watching that same sunset and seeing sixteen layers of color that your brain cannot even begin to imagine.
Scientists were very excited about this. They thought the mantis shrimp must be seeing the most incredible, jaw-dropping, mind-blowing version of the world that any creature has ever experienced.
Then they ran tests and discovered something hilarious.
The mantis shrimp is actually not very good at telling similar colors apart. Humans, with their three little color receptors, can distinguish between thousands of shades.
The mantis shrimp, with its sixteen receptors, is actually worse at that specific task.
What is it doing with all those extra receptors then?
Scientists think it is using them as a color identification system. Instead of mixing and comparing colors the way humans do, the mantis shrimp just looks at a color and immediately knows what it is, like scanning a barcode. It is fast color recognition, not deep color appreciation.
So the mantis shrimp is basically saying, “I do not have time to admire the sunset. I am busy.”
It Can See Things You Cannot Even Spell
The mantis shrimp does not stop at sixteen color receptors.
It can also see ultraviolet light, which is light that is invisible to humans. It can see infrared light too. It can also detect polarized light, which is a type of light that travels in specific patterns.
Its eyes can also move independently of each other. Each eye can look in a completely different direction at the same time without the mantis shrimp having to turn its head. So while one eye is watching you, the other eye is watching everything else.
It is like having a built-in security camera system inside your face.
The Two Types of Mantis Shrimp
There are actually two types of mantis shrimp, and they have very different personalities.
The first type is called the smasher. This is the one with the clubs. It smashes things. Crabs, snails, clams, basically anything with a shell that it wants to eat.
It walks up to a crab, winds back, and delivers a punch that breaks the shell open like a coconut. Fast food, mantis shrimp style.
The second type is called the spearer. Instead of clubs, it has sharp, pointed limbs like spears. It mostly hunts soft prey like fish. It waits, it watches with all sixteen receptor types in both eyes moving independently, and then it strikes.
The spear moves so fast that the fish does not even see it coming.
Smashers and spearers are both equally committed to violence. They just have different methods, like different chefs cooking the same dangerous meal.
It Also Has a Good Home Life (Surprisingly)
With all this talk of punching and chaos, you might think the mantis shrimp is just an angry little creature with no soft side. But it is actually a pretty dedicated partner.
Many mantis shrimp species form long-term pairs. They share a burrow together, protect each other, and raise their eggs together.
Some species have been observed staying with the same mate for over 20 years.
So this is a creature that will punch through aquarium glass, see colors you cannot imagine, and also go home to its partner every evening and be a good roommate.
Character? Very complex.
Why Should You Care About a Tiny Sea Puncher?
Besides the fact that it is absolutely wild and fascinating, the mantis shrimp is actually inspiring real science.
Researchers are studying its clubs to understand how they absorb the force of thousands of punches without breaking. The structure of those clubs is incredibly efficient, and engineers are using the same design principles to build better helmets, body armor, and impact-resistant materials.
Its eyes are also being studied to help develop better cameras and medical imaging tools that can detect cancer cells more accurately.
So this small, colorful, punching machine that lives on the sea floor is quietly helping humans build better technology. It does not know this. It does not care. It is too busy smashing crabs.
The mantis shrimp is proof that nature has no limits and no chill.
It sees sixteen types of color, punches faster than a bullet, throws a second shockwave punch just for fun, and still manages to be a good partner.
It is bright. It is fast. It is built like a weapon that also has feelings.
And somewhere right now, one of them is sitting at the bottom of the ocean, watching the world in colors you will never see, and absolutely not thinking about you at all.
Which is fine. That is probably for the best.
