Nudibranch, Catalina Island, California, Selky Charters
The lesson here was beautiful. Before this, I never understood the fascination underwater photographers have with nudibranchs, these strange invertebrate mollusks. After this dive, I was quite excited. I get it.
Also, my primary camera was being repaired during this trip, so I picked up my trusty backup. It was a good reminder to keep my backup camera.
