 Topic: Peppermint Shrimp/Scallop Symbiot?
Posted: December 27 2003 at 10:41am |
|
Some of you might remember the picture I posted about a month ago of my coral banded shrimp eating one of my peppermint shrimp. Well the lone peppermint survivor has, it appears to me, set up some kind of relationship with my flame scallop. I noticed it from the start, but since the scallop was hidden under a ledge I just figured the peppermint liked the same hidding place. Now the scallop has moved more out into the open and the peppermint has followed it. The peppermint is always touching the scallop (except at night when he goes looking for food). Furthermore, I don't think the coral banded likes the scallop. I've seen him chase the peppermint (at night) back to the scallop but the cbs always stops short of the scallop by about 3 inches. The peppermint does appear to gain some sort of protection when near the scallop. Anyone else witness something like this?

My peppermints will sit right on top of two of my anemones. They run there when something chases them, or when I put my arm in the tank and stuff like that. Sometimes they hang out right underneath the anemone so it hangs over them.
Never seen it with a scallop, but I don't have scallops.

I wonder if the "hairs" that come out of the scallops have Nematocysts on them.

No they don't. But maybe the banded coral shrimp (yes Jon here is another debate banded coral shrimp not coral banded shrimp ) doesn't know that. It may be mistaking the tentacles for those of something that does have nematocysts.

I just find it amazing that a stupid little shrimp could figure this all out  . I feel pretty confident that if I were shrunk, given gills and placed in my aquarium, I'd be someone's lunch  . Can shrimp see color? Is it possible that the CBS sees the scallop as another CBS?

I don't know about BCS in particular but: can shrimp see color? Absolutely! In fact some shrimp have around 16 chromophores, where as humans have 3. Shrimp can not only see color but can also see uv, infra red, heat and all sorts of other cool stuff. Talk about amazing evolution for an animal that is stupid enough to get sucked in a powerhead or overflow.
Is it confusing the peppermint for another BCS? Hmm, I doubt it but I'm going to be thinking about that for a while.

That's very cool about the eyesight! (I always wanted x-ray vision).

What do I have to do to get 16 chromophores? And what's a chromophore?

Sorry, it is the color (or any type of EM) wave receptor. It is an incredible sensory organelle. Basically it is the thing in your eye that sees color. Humans have green, red, blue, evolved in that order. But it is possible to have a chromophore that sees things like radio waves or heat waves and stuff like that, we just don't have them.

Hmmm... I think I prefer the CBS over the BCS.
I thought that chromophores were for seeing chrome-afore you run into it!

According to Marine Depot Live, the CBS and BCS are 2 different species:

Actually view that page again......... it has the "Gold" word there but it is on the second line so it is easy to miss. The term Coral Banded Shrimp is incorrect, despite what Jake Jon or Carl will tell you. The term is Banded Coral Shrimp, trust me. The BCS listed on that webpage is actually a Gold (Banded) Coral Shrimp. Thankfully the wonderful collector Diver Tom has it correct on his site http://members.aol.com/dropnet/Shrimp.html with pictures of the two shrimp.

But can you trust a website that says that mantis shrimp are good for reef tanks? I guess it is good for a reef tank if there are no fish, snails, crabs or any other shrimp. And you keep your hands out so you don't lose a finger......
It should say good for species tank.

BTW I am on your side on the shrimp thing; there are many coral shrimp, bandedB golden etc. but there are not banded shrimp, just banded coral shrimp.

I think all this discussion shows how important the scientific names are.

I just thought i would mention... Last night while looking through
Invertebrate Zoology 6th ed. By Ruppert and Barnes there was
the shrimp, Stenopus hispidus. Common name the: banded
coral shrimp. Check it out, pg 695.
For those who may not be famimiar with this book, it is pretty much
the bible of invert. zoology. And anyone who has had the pleasure of
taking the class is probably more familiar than one would like to be.

I have that book at my parents house. Crap, now I have to run over there to see it. That is great, if it does say what I said because I feel pretty good. Stenopus hispidus is called the banded coral shrimp, thanks djangoboots.
