A common image in underwater photography is a Sharksucker with a shark or Clownfish in Sea Anemones in the Pacific waters. Both are revealing of a certain harmony of creatures in the sea. One such instance is when fish go to a “cleaning” station where another fish variety will clean them as illustrated with Yellow Jack being cleaned by juvenile Spanish Hogfish.
It is not only a fish to fish collaboration that exists. Here is an image of a Rock Beauty being “cleaned” by a Ghost Shrimp. What may seem to the observer as an odd behaving fish mobile on the bottom or on some coral is actually a fish getting cleaned.
