Be sure to read about the snapping effect. Mantis are tough, hands down, but they cannot do that!

Either one MAY make short work of crabs and snails. Both will tend to keep carcasses around their dwelling, like a dragon's lair.
Hmmm, I stand corrected. Thanks for the info. Now we can add a pistol to hunt down a mantis?

I believe I've read somewhere that mantis can do this too. Something about the speed of the smash is 30miles/sec or as strong as a 22mm bullet. B/c of the extremely high speed, it creates a very high pressure hit.

IMO, mantis can kill anything with its size. Not only it's the only shrimp that has color reconigtion eyes (true or not I'm not sure but I remember reading it somewhere when I was researching about them), its speed is faster than almost every shrimps.

Just my 2 cents XD

I currently have a mantis alone in a 6g nano cube and I also have a pistol in my 37 reef. The mantis shrimp would hit the pistol so hard and fast they would most likely just explode into little shrimp bits.

I dont think a wimpy pistol shrimp could EVER have a chance against an animal that can do this....http://ib.berkeley.edu/labs/caldwell/rubiksindex.html

If you believe everything that wikipedia had on the snapping effect, you need to take some non-theoretical physics classes. I mean, 1,000s of Kelvins? If you could get even an area the size of a pin head to that temperature in water, you would flashboil hundreds of gallons, killing anything around it...including the shrimp. Shrimpoluminescence....

If you google it, you will find the supposed web-page this comes from. Follow the links, only two of them work, one leads you to what I will agree appears to be a foreign college university site. Then read the report on it, they are assumptions, theoretical analysis.

While I am not saying that the cavitation wave nor the light does not exist, I agre that it is quite possible, 5,000K would be a temperature that no living creature would be able to be near. And again, reach temperatures that high, regradless of pressure would either flashboil the surrounding water, or seperate the water into Hydrogen and Oxygen atoms along iwth seperating all the ions of any trace elements, including the salt, in the surouding water.

So that you know, anyone can post anything they want at wikipedia...take what is on that sight with a grain of salt.

I tend to agree that the mantis would win out. Pistols are not really set up for predation as a mantis is. The most common types of stomatopod that hitch hike into the home aquarium are of the "smashing" variety. They use a club like appendage to smash or crush prey. Of these, Gonodactylaceus falcatus and Pseudosquilla ciliata are most common. These species really are not the sea monsters they are made out to be but do pose a high threat to all mobile inverts and mollusks. Both mantis and pistols are known for creating the tell-tale popping sound. Some say you can tell the difference by the variety of the pops, several in rapid succession vs. random pops. This has proven to be a very poor mean of ID. the best way to is to get a visual ID and go from there.

I do not recall anyone saying you were wrong. Only people weighing in on the matter. However, the links you provided (while interesting) do not really speak to compatibility of the pistol or suggest a species-only environment for it. Just about every source I have found on the mantis strongly suggests a species-only tank and sites crustaceans and mollusks as its main source of food. They are also revered as highly intelligent predators. Sorry, I think the ball is still in the court of the mantis.
