These cleaner shrimp often perch on the tentacles of an anemone, swaying their body and antennae to attract fish. The Spotted Cleaner Shrimps [Periclimenes yucatanicus] live in association with a variety of anemones, including the Giant Anemone seen here. I took this picture on our last dive, in the shallows at Tori's Reef in Bonaire. There was a strong surge, which made getting this little shrimp in focus quite difficult.
