The title of Crustacean applies to a wide range of marine animals so it's a nice broad category to lump my photos into. This category includes Crabs, Shrimps, Mantis Shrimp, Lobster & Krill, technically it also includes barnacles, but I won't be taking any photos of those, so don't worry. Keep an eye on this gallery if you are a fan of night diving, because that is when the crabs and shrimps really like to come out and play on the reef making them much easier targets for me and my camera.
