Wow after hearing all of the horror stories about people having there fingers cut off while collecting wild coral I don't see this being a smart idea. Then again they are extreamly smart inverts so who knows :neutral:.

neat video, needs to read up on cavatation a bit though, it can't forma bubble between the claw and the surface being struck as this is a high pressure zone, the bubble would actualy form on the back side of the claw and whould implode when the claw stopped moving fast enough to maintain the low pressure zone behind it. the effect of the implosion would affect the claw of the mantis more than the prey, but there could be some sound wave generated that might be able to stun suseptable prey.

wow, intense!! I would not be able to do that as I would fear my finger getting chopped off!:laluot_14:

FYI stircrazy, your website Island Aquatics doesnt work

Not a very smart person. He will get it one day...

How about this...
What if Mantis just recently dropped his old exoskeleton and new one is still soft?
There is no way to tell for sure but Mantis will not strike in times like these.

yup, I know.. it is under construction anyways.. one of these years I may finnish it...

steve, the species seen in the video is Lysiosquillina maculata, a spearer. It isn't capable of cavitation. It could still do major damage witth those great big sharp raptorial appendages and spined telson though.

If the mantis in question were a smasher, still no cavitation would occur. the claw is a small enclosed fixed volume space. No cavitation will occur within the claw or outside it because air is too thin to form such a steep pressure gradient. The claw may still be damaged simply due to the extreme forces the muscles exert on it. The damage would likely be severe if the animal had just moulted, but would also be more reluctant to strike as well. My guess is that the animal was freshly moulted or very unhealthy.

Crazy!
