strike impact

[cuda6872]

Has any data been collected on the strike impact of different species. Just curious as to how hard a full grown G.Smithiis' strike is.

i dont think so, but my mantis has wacked me a few times (3-4" peacock) and it didnt even open the skin, but when he popped me he probly wasnt doesnt it his hardest either..

is it more or does anyone wish there shrimp could breathe oxygen and just be able to hold the lil guy, he just looks so good i can see him crawling all over my arm

The strike of the bigger stomatopods has been measured at the same impact pressure as a .22 bullet, or a pneumatic jack hammer.

yeah, but what about the mid sized ones?

 

[edr42]

Dunno, but i'm not game to stick my hand in and find out.

anybody that does try to find out by sticking their hand in a mantis tank please, let about 3 people video tape it from different angles so all of us can see first hand the outcome!

well here is an extreme slow motion video of a peacock mantis striking, if you look carefully, there is a flash of light at the moment of impact caused by cavitation,

here's the site it came from

well i found more cool stuff there abt 3 seconds after i posted
here they are

the flash of light i told you about

video of a strike, and how much force is exerted at the time of impact, does this answer your question?
