The pistol shrimp can shoot a blast of water at a speed of 100km/h and at the temperature of the sun.

Re: Pistol Shrimp
That was really interesting. Does anyone know the name of the documentary this video came from?

Re: Pistol Shrimp
Yeah i have a hard time believing it reaches the temperature of the sun. The sun is really friggin' hot. It would melt the pistol shrimp itself to be that close to that kind of heat - we're talking millions and millions of degrees celsius.

Re: Pistol Shrimp
What they've meant was the surface temperature of the sun which is ~4000°C.
And what causes the heat up (and propulsion of the fluid) is actually the mixing of two chemicals in a reaction chamber in the shrimp's head.
This IS real. Yet I'm still not sure about the temperature of the fluid being a few thousand degrees celcius. That's still pretty much for a chemical reation.
Well, it's a british TV documentary... ;) so what do you expect? They're not what they used to be.

Haha, forget what've written. I actually wrote that before I watched the video... sorry.
Ok, first of all, it's still absolutely real but it uses a totally different effect than what I described earlier. And by the way, the commentary to this headline is wrong, the shrimp does not shoot water!
It snaps its claw so fast that a bubble is created through the cavitation effect. When this bubble collapses it produces an enormous amount of noise and also some light and heat through the effect known as sonoluminescence, which can reach very high temperatures in a tiny space.
What actually kills or stuns the other fish is the noise, they're not "shot" by water but by a sound wave.

Re: Pistol Shrimp
yeah, sonic weapons! :) Reminds me one of my favourite games (X-Com: Terror from the deep) where you have to do technology researches for that kind of weapons and fight giant shits underwater. Good ol' time!

Duh! I thought I recognized 'Pistol Wimp' resembling something other than 'Pistol Whip', but I couldn't remember.
So, a random, maybe-deserved thank you for hubblemedia for this chance encounter between me and realization.
