This page and vids were posted in my local club site.. thought this was crazy, so here i am to show you guys.

Basically, the mantis shrimp they say is causing cavitation near the snail shell when it strikes. They have that much force in the strike. Id hate for one to miss and hit someones glass tank :eek1:

High speed video of the Cavitation

And a quote from the site. Thought it was pretty amazing. Enjoy.

While recording these images, we noticed cavitation bubbles forming between the limb and the snail. As a result of the limb’s extraordinary speed, the water cavitates (vaporizes) when the limb strikes the prey. Cavitation is a destructive phenomenon; when these vapor bubbles collapse, they essentially cause a small implosion in the water which produces heat, light and sound. For example, rapidly rotating boat propellers are often badly damaged by cavitation, to the point of developing holes in the metal.

wow that was so awsome
