What a beauty!

I think it's safe to say this is Periclimenes. A number of species have variable coloration depending on the host organism. This one looks like its mother was a panther grouper. Neville Coleman needs to see this shrimp.

I believe it's a commensal shrimp. They feed on mucous that healthy clams slough off when feeding.

I suspect you're correct.

Andy,

How can we find information on those two genera? Google finds zero hits on either name. That's very odd. Could the spelling be incorrect?

John,
opps, your right I think the spelling is Anchistus sp.

I've owned a clam with one of these shrimp inside. Definitely very cool creatures, as you can see it picking away cleaning the gills of the clam. I did notice that the clam would "gape" a bit wider than usual with the shrimp inside. It eventually left the clam and managed to get itself killed. The clam lived fine for a long time after that.

picture of it still exists here: (over 2 yrs old!)
