Crinoid shrimp

This little shrimp is 1/4 inch long, so pardon the quality of the photo. It was taken in Belize, on Lighthouse Reef. It looks similar to one in Humann's Reef Creature, Periclimenes meyeri, but has spots and red marks on the tail fan, which P. meyeri does not. May be an adaptation in colour to this crinoid, which is a different one than mentioned as the host crinoid in the reference. Can anyone confirm the ID?

Many thanks,

Marli

Hi Marli

yes, I think it's P. meyeri, assuming that Humann's ID is correct

crinoid shrimps are highly variable in colour adapting themselves quite quickly to the hosts

Thanks, Art,

I suspected as much, but Humann states "known only from Bonaire and Curacao" on Black and White crinoids. I figure as it's a pretty new species and teeny, no one's looking. Its range is probably a lot wider than we know. I concentrated on finding the new shrimp in his book, and found four different ones in three days.

Cheers,

Marli
