High speed footage of mantis shrimp strike

[Cattlecruiser]

Did I see a second cavitation within the claw moments after the strike?

[picklesrntfun]

Who else linked here after reading on Cracked?

[reyesryanmjaube]

cracked.

[Phluffey]

This video needs the Rocky theme.

[iHateAnime4LIfe]

Next time, please dont use an high speed oven

[Dialgadude]

I liked the part where one pixel attacked the other pixel.

[yourcathatesme]

it was much more impressive when I did it :D

[Robloxblacky]

i got that he punch like the flash fuck but not really hurt but when he punch a shrimp i put a shrimp on in then he killed it and eated it lol

[TDWP1804]

there is a little shockwave when the mantis hits it  @ 0:02

[Bubbiea]

@TDWP1804 it looks like electricity

[TheBehattedOne]

Now imagine it doing this in fast motion.

[MagnumWave]

Is it my impression or there was a lightning on 0:09 to 0:10?

Woah, super saiyan shrimp! =)

[Guns918Spyder]

I think I would rather get attacked by a lion. :/

[iitjava]

this thing looks like chuck norris' dick actually!!

[napischu]

I'd rather mess with a titan trigger than this badass :>

[altcommand]

This is a "high speed" video? It looks like someone slowed it the hell down. I am not impressed.

[asemoknyo]

@altcommand The "high speed" refers to the number of frames per second of footage (i.e. 5000, which is impressive in itself). If you look at videos in real time of mantis shrimp strikes, there is virtually nothing to see since it is so quick. If you're still not impressed, skip forward to the moment of impact in this video. See the little white bubble that appears? For a split second, the temperature there is as hot as the surface of the sun. THAT is impressive.

[altcommand]

@asemoknyo I see. Thanks for explaining.

[alexmaloy]

@asemoknyo Do you know what that little spark is at the 00:09 marker?

[flameboarder777]

@asemoknyo the sun comment isn't correct. Cavitation is caused by a change in pressure, not temperature...

[affsafafaa]

@flameboarder777 Well you see, when the bubble is formed at the moment of impact, the surrounding water wants to get in it since the gas in the bubble has a lower pressure than the water. This leads to the bubble's collapse and that phenomena gives away energy in the form of light, sound and heat. This is a real problem with ship propellers and other high velocity objects moving underwater, since the temperature can cause the surrounding water to boil, damaging the object.

[linddk88]

@flameboarder777 "(...). Because they strike so rapidly, they generate cavitation bubbles between the appendage and the striking surface. (...)". Quote from wiki :). There are some very interesting facts

[Jistga]

@asemoknyo are you serious about it being the temp of the sun for a split second!??! That is amazing!

[AceofDlamonds]

@asemoknyo

bubble hot as the sun? sorry bro that is the pistol shrimp......mantis shrimp is pure force....

[Zakerandsaisu]

@AceofDlamonds The Mantis Shrimp does actually produce a small bubble and sonoluminescence quite like the Pistol Shrimp, but you're right that the heat from the Mantis Shrimp's bubbles is nowhere near the sun-like Pistol Shrimp's clicks.

[AceofDlamonds]

@Zakerandsaisu

oh cool...for most small creatures the difference doesn't really matter as they would be KOd with a single hit either way =D

[Viplexify]

@asemoknyo So hot as the surface of the sun. Lolz, man. Lolz.

[aznrevlazn]

@altcommand Hi, my name's altcommand, and I am an idiot.

[altcommand]

@aznrevlazn Ohoho. You're so funny. Also a bitch, for commenting on something that has NOTHING TO DO WITH YOU. GET A LIFE, RETARD.

Good day.

[Shpongl3]

@altcommand such a retard

[altcommand]

@Shpongl3 AREN'T YOU CLEVER.

[raniman]

@altcommand I bow down to your stupidness, Sr.

[Deradundrum]

Don't. Fuck. With. That. Shrimp.

[lastpokemon]

crappiest vid ever!!

[BowHunt1229]

that little buble that is created is the temperature of the sun for a split second

[Staticshriek]

@BowHunt1229 thats the pistol shrimp! matis shrimp just strikes with the power of a 22

[BowHunt1229]

@Staticshriek nope...look it up....some scientist chick did a little presentation on it...to vaporize the water it has to be that hot

[Staticshriek]

@BowHunt1229 Youre probably right, i had just see this implosion thing from the pistol shrimp first, and thought you had gotton the two mixed

[getkristan]

@Staticshriek This doesn't strike with the power of a 22. The claw *accelerates* at the same speed as a bullet. Not the same thing. Sure, they can deliver a nasty knock, but to say it would be like being shot is flat out wrong. Tons of people say that, but it is basically a myth spread by those who cant be bothered to actually see if its true or not (which I just did after hearing the whole "force of a bullet" thing and thinking it sounded unrealistic).

[SkoalMint205]

the crazy part is that this is underwater. imagine how fast it would be if it were in the less dense air.

[Pixelrelated]

Caviatation bubble. Basically the water moves so fast, and it can't exactly escape from the object moving towards it so it creates tremendous amount of pressure which is around 5000 degrees C.

[bjsparntz]

Holy shit! Did you see that cavitation.  I haven't seen cavitation like that since... Well, never.

[monkeyboy2234]

cool

[CARAHMELL]

LOL

pompey the boxing shrimp

[elementInfinitium]

This shrimp would fuck Chuck Norris' couch.

[bazengao]

@elementInfinitium he would if wasn't the fact that chuck norris kills the little bastard just looking at it!

[X1mtheDespot]

Those things must eat a lot of spinach...

[Elfuego177]

HA HA HA HA!!!!!!!!!!!!!!!!!111

[thunderdpa]

i can beat up that shrimp...

[elkofdeath]

Something weird happens at the point of impact. It looks like the carapace liquifies, for a moment.

[GOZERmantis]

yeah. they punch so fast, at the point of impact it kind of makes, for lack of better words, a sonic boom. a visible burst of energy waving through the water.

[lorenzvc]

the impact makes the water inbetween the claw and snail BOIL , steam. generating heat , pressure , even adding to the damage. (no bull)

[WW3]

@elkofdeath That's the water boiling due to the sudden change in pressure. Solids don't turn into liquids no matter how hard to punch them, powder pehaps, but not liquid. An hero plz.

[Leif903]

that isn't the solid being pressurized that creates the light, it is created from the water being compressed so much that it creates energy. It evaporates instantly. Thus that energy creates light.

[Leif903]

I was wrong, it isn't that it creates high pressure. It creates cavitation bubbles. And cavitation bubbles are vapor bubbles that form when water moves really fast. Basically, when water moves fast enough, areas of low pressure are created, which causes the water to vaporize and form cavitation bubbles. [] When these bubbles burst, energy is released in the form of light, heat, and sound.

[chuckp411]

i see where you are going with thai but that heat is generated because of the extreame preasuse generated by that punch

[BowHunt1229]

@chuckp411 the heat is created from the tremedous friction of the speed of the claw vs. the still water

[cinder2009]

chuck wouldn't stand a chance

[AnthonyIsCoolio78]

mantis shrimp are the crustacious spawn of chuck

[hypernation2007]

Win.

Also, CRACKED.

[PedroAC77]

how badass. Cracked ftw!

[ChowzaEXE]

Adorable, deadly, evil.

PS CRACKED

[99frys]

wait no, I was thinking of those bullet shrimps or whatever they're called

:\

[ICaughtAMarlin]

No, I'm pretty sure they both do. The heat doesn't really add that much of an effect to the punch though, cuz it's so short-term

[99frys]

Don't forget that their punches produce heat up to several thousand Kelvin via cavitation.

[tdballard22]

that punch has the equivalent acceleration of a .22 caliber bullet

[benj1623]

imagine getting hit in the balls by that thing....

[hitmankillzone]

benji if u do get hit in the balls with that, then u won't have any left

[Maverick2736]

They sure don't call these things 'thumb-splitters' for nothing...

[jpetrucci05]

cavitation bubbles like the pistol shrimp produces...amazing inverts

[Thewaterofthepool]

so fast it creates bubbles !

[Bullzeye95]

That right there is why the mantis can kill an abalone inside it's shell without breaking it. They'll hammer away, and each time they hit the cavitation shockwave transfers to the shell to the abalone. Eventually it gets stunned or dies and opens up so the mantis can eat it. Same goes for anything else with a shell in the sea. These guys are pros.

[jcallesano]

it produced a shock wave wow

[Swieft]

These guys are pretty slow.

..=3

[Nemersis666]

stick ur finger next to 1 and see if u can dodge it :)

[RedLightBulbs]

Wow. Check out the cavitation bubbles from the shock made by his claw.

[withoutamartyr]

I love how this thing is at 5,000 fps and that claw is still moving pretty fast.

[SeksYxBoI]

dam i want one of those! but too expensive..and they hurt things..so nvm lol

[gadadhoon]

expensive? Dang, those things were pests in our tank.

[RennTaPenn]

how much are they?

[JohnFuckingLennon]

I have no idea what I'm looking at.

[Thenebrosity]

BAHAHAHAHA There's YouTube for you, you can spend hours and hours watching videos and not have the slightest idea what you're looking at.

[daza1992]

lol i got 1 in a plastic bowl, me m8 didnt want it in his tank and didnt want to kill it lol

[asemoknyo]

Yeah, they're awesome animals, just kinda not good to have in glass tanks with delicious pretty things to eat

[gundamWWW]

I came to this video because I thought I would learn about the Chinese Martial Arts Matis Style but all the video ended up making me do is get hungry and want shrimp... Oh well I'm happy.

[caponeman1234]

Search for Sheila Patek. That is from her stomatopod research grant video.

[asemoknyo]

Oh cool, thanks! I'll look up her paper.

[suicidalparrot]

Man, those suckers sure are powerful!
