Commander, I saw your other post, earlier. I didn't add to it, because I am no expert on shrimp ID... and because this one (you didn't mention in this new post thread) was collected out in the Mediterranean, and I don't think is a commonly available LFS species. I agree with the post in the other thread to try the invert forum... esp people like LeslieH, who work in natural history & taxonomy. Most people in the reef forum are most familiar with species that are common in the hobby, and there are hundreds of species of shrimp that never make it to aquariums. What part of the Mediterranean was it collected from?

Ghost shrimp (Natania sp.) are only FW as far as I know, though I agree the second resembles one.

When my peppermint was first added to the tank, it blanched in color and actually very much resembled the first pic.

Looks to be one of the Palaemonidae. Not terribly sure, but look up the family and see if/where yours falls under it.

South mediterrenean. Near Italy

Can a Reefcentral Moderator post this thread into the inverts section so I don't post again there too.

Thanks alot.

Also I asked a mod to move if no good replies....

I can't do a mediterranean shrimp. This calls for Spawner who's a shrimp expert!

It looks like it has a hump kinda like a camel shrimp? Just doesn't have the color of one. Just grasping at straws. Just thought I'd take a stab at it.

Sure looks a lot like the Penaeus vannamei that I buy from Seawater Express (http://www.seawaterexpress.com) to feed my frogfish.

For whatever reason, Commander said in the other thread that it was definitely not white shrimp...

Does anyone have an algorithm/decision tree type thing for IDing shrimp? Similar to what is in the Peterson's field guides for entomology.

02/05/2006, 12:55 AM
Yes Pandora is right.

I checked some people suggestions and when I checked about the white shrimp it is totally different.

Guys the most similar that I found to my shrimps is the AMANO SHRIMP.

Please check it out and tell me if I am right.

Thanks alot.

Amanos (C. japonica) are also only FW only (plus, they don't come from that part of the world). I have some pictured in my homepage in the inverts section, if you want to look again... they are in my planted tank.

I'm not sure if there are more than one species of white shrimp, also. From what I understand, most are used as feeders for SW aquaria when young, but are species of food shrimp (for human consumption) when they grow larger.

02/05/2006, 12:01 PM
lol thanks for pointing that out Pandora.

They are very similar to my shrimps, but for sure they are not they because mine are salt water shrimps.

I cannot bebelive no one here can ID this shrimp.. I wish to know what are these shrimps..

This group is kinda problematic and it usually takes an expert. Additionally, the identification is not based on color or general shape alone.

02/06/2006, 02:40 PM
So what in your opinion ROMUNOV should I say more for helping people identifiying this shrimp ?


02/06/2006, 03:00 PM
Personally, I think your pictures are about as clear as a layperson's photos are going to get, and you gave a location for collection. The problem isn't that.

It may come down to a certain kind of serration on one set of claws that separates out one group of shrimp from another (I don't know, I'm just guessing). It's like this in entomology, so color photos don't really help, because as romunav pointed out, it takes more than casual observation of overal color patterns and shapes. Real experts will know what to look for (which is why I was asking for the taxonomic algorithm), most of us just look and say, "hey, it sort of looks like my camel shrimp, but it doesn't look like my skunk cleaner", which doesn't really help.... there are probably hundreds of species that look similar to the clearish gray shrimp shown, most of which will never be captured for the aquarium because of their dull color. I am tagging along to this thread because I am curious myself and want to learn more about shrimp identification.

SEnd a PM to Spawner. As I said earlier, he's a shrimp expert & a reefer. Probably the best person on the forum to answer your question.

02/07/2006, 12:23 AM
Guys I messaged PM to Spawner like you suggest.
Let see if he can help us.

Thanks alot

Sorry, I've been writing, and writing, and writing, and yeap, writing.

Color can be a great way to ID shrimps, just not when they are preserved or with species that can vary coloration. Most of the species I work with we develop coloration keys or use color plates in the publications because color is such a great resource.

I don't really do much with the shore shrimps, but Cédric d'Udekem d'Acoz would know the species off hand from the photo. I'll send him an email and see if he responds. He is really busy so don't count on it.

Family is Palaemonidae. Common shore, Rock Shrimp. No really something that i would keep in my reefs. Could be Palaemon or Palaemonetes; my guess would be Palaemonetes but I can't see enough of the shrimp in your picture and I don't work with this group much. The ecology of the group is pretty much the same, both are common along rocks and shore lines, pretty much will eat anything they can.

Check Cedric's website out, be respectful to his requests on copyrights and links.


Les, I have a few worms for you, from the Keys, how to do you want them? I did find this great fire worm 25cm long, my hand was numb to my elbow :eek: for about 6 hours. I hate those things.


02/07/2006, 02:20 PM
Andy -- Are they live or dead? If dead, I prefer fixed in formalin & transferred to alcohol. I know shipping in alcohol is a pain so it's okay (& even legal) to ship in 5% formalin. Thanks!

I admire fireworms but I don't touch them intentionally!

02/07/2006, 02:29 PM
Their still kicking. Who said anything about intentionally. I had my hand somewhere it shouldn't have been and it sure let me know it.

02/07/2006, 02:47 PM
Thanks Andy, and thanks for the link. Good job to Amphiron, who got the family dead on.

OUCH!! I actually don't know the best way to ship live worms. Everything I ship is dead. How would a LFS do it?

And GOOD NEWS, Andy! We got the Lysmata back today. 11 lots, 3 id'ed as L. wurdemanni & 8 as L. intermedia by MK. We need to catalogue them & then they'll be in the mail.
