Aggressive, reef-dwelling mantis shrimp take more than one first-place ribbon in the animal kingdom. Outwardly resembling their lobster cousins, their colorful shells contain an impressive set of superpowers.
There are two types of mantis shrimp, named for their attack mode while hunting prey: smashers and spearers. With their spring-loaded, weaponized legs, these predators can crack a snail shell or harpoon a passing fish in a single punch.
The speed of these attacks has earned the mantis shrimp one of their world records: fastest strike in the animal kingdom.
Scientists are finding that another of their special abilities -- incredible eyesight -- has potential life-saving implications for people with cancer.
Mantis shrimp can perceive the most elusive attribute of light from the human standpoint: polarization. Polarization refers to the angle that light travels through space. Though it’s invisible to the human eye, many animals see this quality of light, especially underwater.
But mantis shrimp can see a special kind of polarization, called circular polarization. Scientists have found that some mantis shrimp species use circular polarization to communicate with each other on a kind of secret visual channel for mating and territorial purposes.
Inspired by the mantis shrimp’s superlative eyesight, a group of researchers is collaborating to build polarization cameras that would constitute a giant leap for early cancer detection. These cameras see otherwise invisible cancerous tissues by detecting their polarization signature, which is different between diseased and healthy tissues.
--- How fast is the mantis shrimp punch?
Their strike is about as fast as a .22 caliber rifle bullet. It’s been measured at 50mph.
--- What do mantis shrimp eat?
The “smasher” mantis shrimp eat hard-shelled creatures like snails and crabs. The “spearers” grab fish, worms, seahorses, and other soft-bodied prey by impaling them.
--- Where do mantis shrimp live?
In reefs, from the east coast of Africa to the west coast of Australia, and throughout Indonesia. A few species are scattered around the globe, including two in California.

one punch shrimp
SIRANUS noice
SIRANUS ONE PAUUUUUUUUUUNCH
SIRANUS its not one punch tho...but its like saitama's pet XD
no two punch shrimp
I guess you could call it *shrimp-tama*
Came for the cool mantis shrimp facts, was blown away about polarized light
Paul Thornton same here !
same here
Paul Thornton ikr (I know right)
😂😂😂
I still don't really understand the concept.
That shrimp that drags them under the sand could be in a horror movie
Choose us creepy weeaboos instead rem lmao
Daria you gotta watch a video of the bobbit worm
@@apothecurio I was just on my way to write exactly the same thing when I ran into my comment already written by you :D
You haven't seen the bobbit worm then. That one is freaky!
@@Enonymouse_ I saw it to me its cute But Its kinda amazing how it Attacks
Even with hexnocular vision, the mantis shrimp *still can't* see why kids love Cinnamon Toast Crunch.
I used to see why but then I took a giant mantis shrimp punch to the knee.
JellybellyWaffles bringing back the classics
🤣
I am eating ctc right now ( ͡° ͜ʖ ͡°)
So the mantis shrimp punches the kids and the cereal.
Had one of those little thumb splitters in my reef tank and it eventually managed to kill all the fish.. one by one.. then crack the glass. Amazing little buggers.
***** Luckily you hear it when a 70 gal. tank cracks, and things were contained... eventually :)
***** they're less than three inches long.. no match for the average shoe. In time I got a moray that took care of that problem for me.
Secret identity Oh gosh....I would be so terrified. Lol!!!!
They come in in the live rock.. I don't think anyone would willingly get one!
What did you do to them? Did you return them or kept them in a seperate tank?
Hi all...I'm the producer of this episode of Deep Look, Elliott. We've been in the field the last two days on the next awesome show, but I'll be answering your questions soon.... Keep em coming! Thanks for watching, BAM! -EK
Deep Look I really interest with mantis shrimp especially it eyes like 360° and More color vision. awesome
I love you - you're awesome... this much be so fun filming
Deep Look --> Hey Elliott- just want to let you know that i think Deep Look totally sucks.
JK this channel is amazing and i think the mantis shrimp was a friggin brilliant subject! well done.
Deep Look -> i imagine a video on sperm, eggs, and human conception would be a huge hit for your format. Would likely help capture your female market also
We've got one! Check it out: czcams.com/video/9mv_kuwQvoc/video.html -EK
Hands down the best mantis shrimp video out there - a perfect, simple and understandable explanation of how their circularised polarised vision detection works and what that means. :)
In addition to their epic eyesight and speed, their telsons (the shell on their back) is incredibly strong and engineered in such a way to protect them from the blows of other mantis shrimps (as they tend to crack each other blows there).
Their microstructures are fascinating, and have great ways of preventing cracks from forming and propagating, which means that they also have one of the most resistant carapaces out of the animal kingdom.
One more way they are epically cool. :)
Thanks, Inés, for the additional facts! I feel like we could do several episodes on mantis shrimp, for sure. The circular polarization animations were created by our colleague Teodros Hailye.
Indeed! I was very impressed by how much you managed to squeeze in 4 minutes whilst keeping the explanation as simple as necessary but without leaving out some of the more complex terms.
I had no idea polarised light could be used in a medical setting (the example we usually hear from mantis shrimps is how their eyes inspired Blu-ray players), which is tremendously interesting.
The animations were spot on too, kudos to Teodros! :)
True Facts About The Mantis Shrimp by Ze Frank is pretty cool as well.
Deep Look you guys should totally make another video of the mantis shrimp my & im sure many other hearts were broken when the episode ended.
Draw Curiosity "Smarter Every Day" made a video focused on their punches that was really in depth. Kind of like this one, focused on their eyes and receptors.
The mantis shrimp might have the stongest Punch, but Deep Look got their Punchline.
Triniswe what about POPEYE.
I’m sure these things eat spinach!
So did he have to go get stitches or no
Real life is stranger than Pokémon
The real proverb is “Fact is stranger than fiction”, but that works too, I guess.
@DMC5 H8RRoleplay he's gotta flex.dude. weird. or not weird it still is a flex
Oh no XD
@Azure Nightmare You only say that because you're not elite like us.
"Lurantis used skull bash, It was too effective"
I was on a field trip and picked one of these up not knowing what it was, when the guy in charge saw he screamed and slapped it out of my hand haha
Dude saved your fingers
Dude saved ur hand XD
was it a girly scream?
Totally happened
If you pick up a sea creature with this color pattern while not knowing what it is, you will win darwin award pretty soon.
The mantis shrimp has to be one of the coolest products of evolution!
God created it.
Evolution, unlike god has proof of existence.
@@alfredozambrano7641 shut up
@sanju2 men made god
Cringe Generator Actually, the only reasonable explanation for the cause of our universe is a single infinite entity.
I thought I've seen all there is on mantis shrimps from the other videos, but as it turns out there is far far far more to the mantis shrimp than only its punches. Firstly a SPEAR MANTIS holy hell that's cool and then polaroid eyesight! No one looks into things like Deep Look no doubt.
RNG lol. Deep Look takes a deep look for sure
RNG imagine a color you can't even imagine. Now do it 9 more times. that is how a mantis shrimp do.
Question, could that thing break my finger?
Yes. They are not good pets because they can break the glass of the tank!
yep a manta shrimp smashed through the glass and wandered around the Monterey Aquarium in california for 4 to 5 hrs before it was recaptured
One Punch ManTis Shrimp!
THESE WOULD BE DOPE POKEMON!!!
Fighting/Water type
I think clawitzer would be more accurate, with the whole punching with the force of a bullet thing
BUT I made something ssooooooooo:
Strimp the mantis shrimp pokemon
Fighting/water
Spear form:
Strimp with spear arms can impale even the hardest of armors. When they strike, their arms move faster than sound. Spear form strimp have a deep rivalry with hammer form strimp.
Hammer form:
Their punches can shatter steel. Like spear form, their attacks strike quicker than the speed of sound. They have been observed eating shellder and cloyster. They will fight spear form strimp on sight
There's an anime called Terraformars and one of the guys have that ability because humans can have their dna spliced with animals.
I’m not sure if this is what it’s based on but sun and moon made one soooooo
1:07 I'm worried that some people might misunderstand this analogy. The black spots are just where the mantis shrimp's eye takes light in from the direction of the observer. The mantis shrimp doesn't track objects using its black spots. All facets of each compound eye take in light simultaneously from their respective directions. The black spots would simultaneously be in different places to different observers.
Thanks for the comment, Kenneth. We struggled with how to explain the appearance of "pseudopupils" to everyone in our short format. We landed on using an analogy to human pupils that doesn't tell the whole story, but gives people a general orientation and, we hope, a good introduction. For anyone interested in further reading, here's a good starting place. Thanks again-EK www.journals.uchicago.edu/doi/pdfplus/10.2307/1543312
In case your mind wasn't blown by mantis shrimp yet, this video will do the trick.
The mantis shrimp has been one of my favorite creatures on this planet for a long time, but it just rose to #1 after watching this video! I had no idea that there are spearing mantis shrimp, nor did I know about the polarization detection. So cool!!!
Thank you, Garret. What other creatures do you like?
Deep Look would love to see something on gibbons- they are my #2
Hexnocular vision.... Yep, that's what Amy said...
Yep.
Yep.
1:48 man I thought I would see Joseph Smith come walking in frame. Brought back some bad memories.
Incredible quality as always :) Thumbs up!
Thanks so much!
0:47 I can't be the only one that laughed at its little eyeballs sticking out of the sand, imagine having to do a double take and noticing 2 little eyeballs sticking out of the sand aggressively watching you as you walk by😆
2:28 I wanna see more of this, shrimp battle, that's amazing!
I love the way their eyes move about on those stalks. These magnificent creatures look as if they came from an entirely different planet.
Great quality content as always. Nice!
Thanks, Adrian!
Oh, that's my boyfriend. Yeah! Adrian.
Who's your boyfriend?
you. XD
No I'm not. But if you're a girl looking for one, pm me.
It's always a good day when Deep Look has a new video! Wouldn't it be great if such high-quality were the rule, not the exception? Gotta dream...
Wow, thanks!
+Deep Look U guys just got a new subscriber
Thick information in 3:59 min video. And being enjoyable to watch too. Props
Hold up, did she just say: “A shrimps gotta eat, and do do we”?
From their highly adapted eyes to their powerful quick-striking punches. The mantis shrimps have to be by far one of the coolest animals of all time.
Fantastic quality video! Great job!
Thank you, Virginia!
you guys are nothing less than amazing. You guys should get a lot of recognition.
Thanks!

Never forget.
the hash slingling, the spine chingleing, THE HASH SLINGING SLASHER
This channel is so underrated. So happy I was part of the 50k subs. The cinematography is truly breathtaking. I honestly wished they played videos in this style than the boring ones at my lectures.
Thank you so very much!
One of the best episodes in my opinion
Although I wish the video was a bit longer 😢
I really did not know that any animal used polarized light before now, natural selection is so cool. I suspect we'll eventually discover an animal that use and/or detect radio waves.
+SlyPearTree Can you imagine how advanced civilization would be, if we could all get along, and use the trillions of dollars spent every year on defense, for research on all of our diverse and incredible wonders of nature?
The answer to everything is within our grasp
Ima Tumor Mankind develops when there is a common enemy
zlidyh5 Sorry don't agree. Mankind may develop faster with common enemies, but what is the hurry? People will still have the compelling desire to excel that most are born with. Splitting factions create enemies and alliances that compete for resources, which drives development. But would Mankind cease to develop without enemies and aggression? nah. Thanks for challenging me.
Ima Tumor I didn't mean in a technological sense. I was addressing more of the part where we could get along better, and sort of implying that because of that we would develop further.
zlidyh5 I misunderstood, which happened once before. I believe it was spring of 1997. So now it's twice.
Ha Ha lol lol lol
Loving it as usual. Clear & Concise words on a specific animal that describes not only the creature, but the less known nuggets. Accompanied by the highest production value. This is the reason I'm subscribed.
On another note, have you folks considered doing a microscopic creature, such as the Tardigrade? :-)
Why yes we have. (I'm one of the Deep Look producers). Thanks for watching!
Gabriela Quiros Great to hear it's under consideration. I'll keep my eye's peeled.
-Cheers
+Corey Doyle, yes! I can always go for some extremophiles like water bears. IMO, they look like the stuff nightmares are made of, but their hardiness is always fascinating.
+Asummersdaydreamer14 water bears are my favorite living being!! They are really cool and I think its "legs" are so cute
Are you going to release a Behind The Scenes video? That would be awesome!
Oliver P this is mostly recycled footage I think, I've seen some of it from Dr Roy Caldwell and I think the spearer footage is a clip from Kharn.
They have one of the BTS of the caddisfly video (though I won't lie, I would watch a BTS for every video! :) Underwater photography is hard as is, and with mantis shrimps... well, let's say our Zoology department don't keep them anymore because they smashed one aquarium too many).
This episode is almost entirely original footage. I filmed the spearer shot (0:51) myself in Caldwell's lab. The footage might look similar to other shots because there are only so many angles you can get in tanks that size.
Truly beautiful photography, thank you so much.
You are welcome, Paula.
she has the voice of an angel 😇😍
Never thought shrimps were so complicated
my favourite animal, on my favourite channel. Can't handle it.
I wish you could make a video on siphonophores, fennec foxes, and hummingbirds.
Thanks! We did one on hummingbirds: czcams.com/video/JyqY64ovjfY/video.html
Nice. Thanks, guys =)
Zulhilmi Ghouse na man creepy monster shrimp all day.
I used to work in an aquarium store many years ago, one evening we had a shipment of "live rock" come in (rocks picked up from reefs that have interesting things growing on them, they're popular with people who keep salt water aquariums.) One of those rocks had a mantis shrimp hidden in it, we only found out about that the next morning though. The mantis had come out of whatever piece of rock it had been hiding in and had busted the glass on the aquarium, everything that was in there was lying on the floor slowly drying out.
What a crazy story! Thanks for sharing!
This shrimp has more kinetic energy in its punch than many small bullets
I love these videos! They're short and so informative. And while I do have a Human Resources Management paper tomorrow, I still had to take a break and watch this video. Great work as usual, Deep look👍🏽
Thank you, Rayna, I hope you are able to include some of what you learned about mantis shrimp in your paper!
Beautiful narrating, awesome sound effects + music, top notch quality. This channel needs more subscribers !
Our music for this episode was composed by Beth Custer: bethcuster.com/ . Go check her out!
2:31 *A combo of headbutt and high flip kick. Well done.*
I've seen Smarter Every Day, Scishow, zefrank, nat geo, and minute physics do vids on the mantis shrimp before. But this video has the best quality out of all of them. Can't wait to see what you guys do next
Thank you, Sir - all of those are really great vids.
You need to collaborate more or do something, these videos you produce are marvellous. You should have millions in subscribers!
Your videos are amazing! I think as your channel becomes larger and wiser, more in-depth videos on some of these topics would be amazing! I'm always hoping they continue because you guys put together such great information with wonderful footage. Whatever happens, all the best, and I'll continue watching!
One of the best animal channels on CZcams!
Mantis shrimp, alongside centipedes, hummingbirds, and octopus are some of my favorite animals.
I had no idea their eyes were so amazing.
Great work as always!
This video is actually slightly off. The first shrimp is called the peacock mantis shrimp, and the second is called a zebra mantis shrimp. Also the eyes on the zebra mantis shrimp aren't quiet as amazing as the peacock mantis shrimp.
Don't get me wrong though this is a great video!! Thank you for making it😀
It's amazing how well these episodes hold up, 7 years later
Amazing! Every person that can't comprehend how the extinction of one species can catastrophically impact should be made to watch video's as brilliant as yours.
Hadouken!
I love how you guys show us how awesome evolution and nature is!
I love how much quality and effort you put into these short yet so interesting videos. This is already my favorite channel on CZcams. Keep it up!
Thanks!
I was looking for a mantis shrimp video when I stumbled upon you guys. Now I can't stop binging all the videos you've produced, stunning videography, elaborate storytelling & in depth info. Kudos for the great effort, I'm a fan now :)
I love your mini documentaries! Short enough that it doesn't feel draggy, yet long enough to be informative! Sharing with my friends!
Awesome footage and video. Love the colors.
This is absolutely incredible! Great work! 👏🏼
Thanks Kirsten!
The most underrated channel on CZcams
i showed this channel to most of my friends, and their first impression is about how soothing your voice is, Amy! Like a velvet!
Really enjoyed this channel
If u want more views I suggest putting the title as something more about polarization and mantis shrimp sight, since most of your viewers already know about boxing and spearing mantis shrimp
Agreed; I almost skipped this video because I couldn't differentiate it from the other (huge amount of) mantis shrimp videos by a glance
Good suggestions - thank you.
That moment when you check Deep Look for new videos and then you realize you're not subscribed to them -_-
Damn it...
We're glad you're here now! Thanks for subbing!
Wow this creature looks straight out of a sci-fi movie, absolutely amazing stuff!!!
If I had eyes like those I would have to scared anyone and won the Halloween party for the most scary costumes.
Spearer aka a tiny hydralisk :)
Mindblown. Incredible animal and incredible video :)
That was the most brilliant "subscribe cuz I need money" I've ever heard. Welcome to my feed
Ha, awesome!
Spearer: "Gotta Blend In and be sneaky."
Smasher: "I don't give a f**k who sees me I'll beat them to death."
OMG Awesome as ALWAYS! Keep the hard work!
Best Quality Ever, nice video, keep with you great work
this has been my favorite animal for about 3 years
I am loving these videos, short, concise, to the point.
No pointless blabbering.
Once again, one of the best channels out there. The videos are high quality and the script is written perfectly. I love these videos! They're so interesting!
Thanks, Preston!
so love this channel!💚
I think you should have more subscribers, absolutly! Keep making this amazing kind of videos!
THANK YOU! I've been waiting for this for so long, my favorite documentary channel making an episode of my favorite animal
I found this so interesting
Strength vs dexterity
fnatic vs dexterity
Mantis shrimp make the beams of light circular!! so cool!!
This is one of my favorite animals !
Woah. Just found your channel. Awesome!!!
Welcome!
Can't these little sucker produce light from attacking so fast or is that something else?
Actually, that is right! Because of time, we have to be choosey about what we focus on. It's called sonoluminescence...light produced by imploding bubbles. You can see it in this video: czcams.com/video/aAu2f87QAQU/video.html Thanks for the comment-EK
Deep Look
Thanks for the reply and the video. This is soo cool!
+ce smith you're thinking of danny trejo
Look up the pistol shrimp
I'm in love with this channel!! I wish these videos were much longer! Most videos I wish were shorter but on this channel; I could watch it on end and never get bored!!
Clicks on video about Mantis Shrimp, gets a Red Lobster commercial. Nice.
I subscribed
Welcome!
Ayy, notification squad! :D
YES! I watch your videos everytime I go to bed and I seem to have watched all your episodes XD Nice content as always!
Fantastic video! Those are some highly-complex concepts to get your head around (e.g. circularly polarized light), but you manage to explain it in a simple way that most can understand. Well done.
those sentence in the end.
sooo....
you guys ate the shrimp?
I think is means they need subscribers so they get money so they can eat.
Could be, lol ;-)
What Mac said.
Amazing
These videos are my main reason to visit CZcams these days. Just mesmerizing stuff.
“She’s about to devour a snail.”
ESCARGOON NO
Amazing video, what camera did you use to film this?
Sony FS700R and Sony A7sii with Canon macro lenses (100mm f/2.8 and MP-E 65mm)
Man it's great as always
The name is just..THE HASH SLINGING SLASHER
