apologies if this has been posted already, but I just saw this now. Here's the description off the orginal webpage (which has been taken down due to bandwidth):

http://crustacea.nhm.org/~dean2/crab.html:
This is a video taken in 6000 feet of water. An undersea robot is sawing a 3mm wide slit (1/10th of an inch ... remember that width) in a pipeline. The pressure inside the pipeline is 0 psig, while the pressure outside is 2700 psi, or 1.3 tons per square inch. Then a crab comes along....

Here's the gist of it:

That crab got OWNED!
 
Wow... that crab must felt like crap ;-)
 
I'll need to remember that method the next time I am trying to get that last peice of crabmeat way up in the claw...
 
Oh man, that crab went from 186 bar to 0 bar in just a few seconds, I hope he remembered to equalise! There's a point, do crabs get bent??? :wink:
 
just plain cool to see physics at work. huh!

Physics? Wouldn't that be Hydraulics? Or perhaps Pneumatics?

Idling mind . .
