As unglamorous as it sounds it’s really fun for divers that enjoy finding the little things. Muck diving is usually done at the bottom of the ocean with a sand or sediment base where all of the small macro animals live and hide. This is heaven for macro photographers. Look for small shrimp, nudibranchs, juvenile crabs, frog fish and small octopi and many other camouflaged critters. It’s really important to keep fin action to a minimum as to not stir up the bottom.
