Muck diving, as it might sound, makes you think that you'd be diving in alki-esque waters. In reality its not that far off, but what they mean by muck, is usually just rubble or sand. There are still coral reefs in the shallower regions, but primarily its an expansive flat sandy bottom. Occasionally random oases will crop up, like this anemone, being fiercely guarded by its damsel fish inhabitants, as well as the lesser seen crab.
