A shrimp? in Critter Identification Posted October 23, 2009 Hi everyone -- Some of our members from the Caymans were able to help out Sammy De Grave in his quest to identify this shrimp. This morning he wrote me that the mystery is finally solved. It's Periclimenes harringtoni which was described in 1949. Up to now it's only been known from Bermuda & the Tortugas so this is a major range extension. Even though it's not a new species this is still a very exciting discovery because it hasn't been seen since 1951, the sponge association was unknown, and the live coloration has never been described. Sammy plans to write it up for publication. Has anyone seen it in other areas of the Caribbean? Congratulations to everyone involved!
