    Please ID this crab for me

    Most of the reef rock galatheids I've collected have been reproductive at 1 inch or smaller. In your sump it will probably find a tiny crevice it can wedge itself into for protection.

    Riddle: what has 5 sweepers

    Sounds more like an eunicid polychaete. Does your mystery critter have the same general appearance as the guys on this page? http://www.nhm.org/guana/bvi-invt/bvi-surv/worm-g04.htm

    Abalone??

    Chances are your hitchhikers aren't abalone. Tropical abs aren't that common but there are some other tropical snails that have the same flattened shape.

    Please ID this crab for me

    That's a galatheid crab. They're closer relatives to hermits than to true crabs. Most of them seem to be either particle feeders or eat algae & smaller inverts like pods & worms. Harmless and maybe even beneficial.

    Acro eating shrimp

    Always a pleasure to talk inverts. :D I don't check this forum unless someone sends me a PM so let me know if something else interesting or puzzling comes up. Cheerio, Leslie

    Acro eating shrimp

    Pontonia pinnae is an obligate commensal only found in pinna bivalves. This one is neither an alpheid (although it snaps) nor a pontoninae. Most likely it's a small Coralliocaris or a related genus. For an adult see http://www.vanaqua.org/aquanews/field/images/yaqara.htm This is a coral...

    Thanks, Charles. I'll throw some whirl-paks into my next package for you.

    acro crab

    Do you know the region your coral & the crab came from? We need locality info so the crab boys have a shot at identifying it. This crab post inspired me to post a thread on "crabs wanted" :) You'll find information on how to preserve & ship is at...

    crabs wanted

    Hi everyone -- Want to get rid of your pesky crabs? Why not donate them to science instead of freezing or flushing them? There are some people here at the Natural History Museum of Los Angeles County that are doing a genetic research project on crabs. They need freshly preserved specimens in...

    acro crab

    jnarowe - Inverts are my profession & my passion. I'm a marine biologist working at the Natural History Museum of Los Angeles County as the collection manager for the polychaete section. While I don't keep a tank I'm very interested in what reefers have to say about their animals. Sometimes...

    acro crab

    The best acro crabs are Trapezia & Tetralia species. There are some other good ones as well. The one in your image appears to be a Cymo and is destructive.

    What is it????

    Could be more. They live in crevices and normally come out only at night. If possible they keep their posterior ends inside their crevices which helps them rapidly retract back into it if a predator like you shows up. Dangerous.... well one could bite you (big jaws) and even tho' the bristles...

    What is it????

    Better, thanks! It is Oenone. Since I believe worms are the highest form of life I'd keep him (if I had a tank that is :lol: ) but not everyone feels the same way. :D If you're going to get rid of it I have a worm-loving colleague in Puyallup that might want it for his personal collection.

    Another wild worm..

    Not with that type of body. A peanut worm 10" long would have a much thicker walled-body. Their musculature is different so the appearance is different. Also, they tend to be detritus/deposit feeders rather than sand eaters.

    What is it????

    Please. Oenone is not something most people want in their tanks. It's a mollusc eater. It comes out at night to find snails & clams then covers them in slime. I don't think anyone knows if the slime is toxic or suffocates the mollusc or keeps scavengers away from it. They'll even go after...

    Need Id on this crab

    It's hard to identify these small rock-dwelling xanthid crabs. They're pretty much all opportunistic predators and unwelcome in most people's tanks.

    What is it????

    From that picture I'd guess Oenone fulgida but I'm still not sure. The appendages are stuck to the body like wet hair after a shower. When taking pictures of marine critters keep them in water so the appendages apread out in their natural position.

    Another wild worm..

    It might be a capitellid polychaete. There are some large tropical species in genera like Dasybranchus that would fit this. Take a look at the capitellid I have up at http://www.nhm.org/guana/bvi-invt/bvi-surv/images/worm-07/h0695d.htm Despite being a small specimen you can see the transparent...

    What is it????

    Hi Vicki - Got your PM. Definitely not an amphinomid (= fireworm and what most reefers call a bristleworm). It could be an eunicid but I can't really see enough of the details to be sure. Can you get a close up of the head region? Or take a look at my eunicid & phyllodocid pages & decide if...

    Invertebrate Identification " Shrimp"

    Sorry, I overlooked the little guys. I'm pretty sure they're not P. pedersoni but like you said, it's hard to tell without a closer look. I wouldn't even put those in a family without a close up. There are several species very similar in appearance to P. tenuipes in the IP and the Caribbean...
