I am taking down my 6 gallon nano tank today in order to ship it, it has been sold. For months I have heard a popping sound coming from the tank. Today I think I found the source of the popping. It's about an inch long.



I checked out the mantis shrimp website http://www.blueboard.com/mantis/
the closest I can see is this one: (Hemisquilla ensigera)

Is it a match? Does anyone want this guy?

I don't know a whole lot about mantis or pistol shrimp, but don't pistol shrimp have one big claw and one small claw just like the one you found? They are known to make the popping sound also.

Hi Larry,

It is a pistol shrimp.

Cheers, Ron

That seems to be the consensus all right. From what I can find they are for the most part safe with fish? I would put the pistol into my 40 gallon but I have a mandarin in there.

Hi Larry,

I hate to say this, but identification is not done by consensus.

It either is something or it ain't and the will of the majority doesn't mean squat.


Cheers, Ron

It's quite happily consensus that consensus doesn't mean squat when it come to the truth, hehe, no matter what stock phrases people use that suggest otherwise, hehe

Ron, why do you hate to say it? The statement is most true, of course. I used "consensus" as a figure of speech and got my hands slapped. Nothing wrong with that.

Hi Larry,

I was just at a fish store in Richfield tonight, and I think they tried to sell me one of those. They claimed that went well with a Watcher Goby? Seems that the shrimp can't see well and use the fish as eyes for danger. The shrimp burrows a hole and both it and the fish hide in there for protection.
Kinda cool, they were trying to catch the one in the store and it was popping like crazy!

I think that is what they were talking about. Dr. Ron, please correct me if I am wrong.

I guess it would all make more sense if the "biologists" didn't keep changing the rules of what is what! etc. etc.

The majority may not alway be correct but I think they are pretty close this time.

I do not think it is a mantis shrimp since it does not have the mantis claw appendages. It does look like it is related to the pistol family due to the one big claw.

My pistol clicks more than my mantis shrimp. If anything gets near the goby hole the shrimp goes nuts, to the point it will pick up the offender and dump him in the other corner of the tank.

Do pistol's collapse their entrance at night? Either the tunnel is doing it itself or the shrimp is closing the door.

Hi,

Larry - regarding the quality of the picture.... How many legs does the shrimp have? How many segments does each leg have? It is a good thing pistol shrimps are basically recognizable by the silouette.

bmw - you say: I guess it would all make more sense if the "biologists" didn't keep changing the rules of what is what! etc. etc.

The rules about what is what haven't changed much for a few hundred years. Names change as we find more about the organisms. Hobbyists who apply common names, scientific names, and some pseudo-scientific names of all their own, tend to cause us more than a bit of grief in the hobby.

Trying to apply more than a general term to many of our animals without handson examination is damn near impossible for a specialist who works with the animals in detail. Of course, such niceites don't bother hobbyists or dealers. So we have such great names as Margarite snails, Meat corals, Tree sponges and other names without any true meaning. Kind of like the old mathematical fudge factor of a "variable constant..."

Cheers, Ron

I thought it was a mere hundred years ago that an alga common in our tanks was identified as an animal?

BTW--I have never seen fudge get old in the math department.

Halimeda.
"These jointed, calcareous organisms were long considered to be animals, and later related to the coralline red algae. With the monograph of Barton(1901) the great morphological variation within species was recognized and an approach to classification was made on the basis of internal structure."
Incorrect?

Ron and Bruce:
Hehe. Arguing validity of the procedure of data organization vs. any attendant errors and adjustments in the execution seems a joust with both horsemen heading the same way.

No one's bashing Linnaeus on down, and I certainly hope no one's expecting instantaneous taxonomic nirvana -- human limitations aside, the extinctions and emergence of species stifles that hope.

BTW regarding pistol shrimp, Larry, mine have never bothered my Pterosynchiropus splendidus (Mandarins): the pistols do pop away as a defensive reflex when those two fishies approach.

Hi,

Ya, horge, I kept trying to lead Bruce to the difference between the process and the execution - too subtle, I suspect.

Cheers, Ron

Hey, thanks Horge, for the answer to my mandarin question. The pistol thanks you too as he has been imprisoned for the past day awaiting vindication. I know there are other sources for this knowledge, I just don't always trust the source.
Here's a parting shot for you....I wasn't the one who used the term "pistol shrimp". Which alpheus would that be?

Hi Ron,
Got to admit--you made me smile with that last post.
Besides, I got an excuse to use that hamster!
How's that for subtle.

Larry:
Really want to know?
Then perform the ritualistic "relax it in MgSO4-then soak in alcohol (the shrimp, not you, haha-do the 10% formalin pack-away" and send it to Ron
I wouldn't ask for it back ,though

Bruce:
I love that dancing rodent

Yo Ron,

I guess that process vs. content applies to communication too, ey?

Good luck

Oh, hi MIKE:

I want to apologize directly for confusing you with MLP on another thread (MLP didn't mind though ). Next to the numerous Dougs, Michaels seem to be most abundant on the boards...hehehe

Hi Horge and Larry,

Ah Guys - I don't identify bugs...

These are lower life forms, similar to algea and rednecks.

In years past, while doing some environmental consulting in Saudi Arabia, we shipped in some formalin to preserve the specimens and apparently (from the fellows who accompanied the stuff - I stayed stateside) the Saudis had some poor schlock at the airport drink some to assure that we weren't smuggling in alcohol...



At least it isn't a job you would have to do for a long time.

Cheers, Ron

Hi b,

And what alga might that be?

The rules haven't changed - the data base gets larger allowing a more refined and correct placement.

The basic rules for placement and nomenclature have been pretty constant since the late 1700's.

Cheers, Ron
