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.
The Caribean Reef Octopus [
Octopus briareus] inhabites coral reefs, residing in recesses or sponges during the day. It can be found in the open on reefs at night hunting for food, often spreading itself in a distinctive parachute pattern to attack and engulf prey. This one, found on the Calabas II reef in Bonaire, is using a similar technique to conform to the landscape and avoid detection.
