One of the wonderful things I like about macro photography are those tiny little surprises you discover when you zoom in on your subject while editing.
What seemed at first to be a solitary nudibranch, in this image
Ceratosoma brevicaudatum, turned out to have a few hidden gems, those little creature just too small to see while diving.
In this image there are three minute shrimp around 1mm in length cleaning the nudibranch's skin while a minuscule amphipod of less than a half a millimeter in length hovers above.
Love those little gems.
