I've taken sand samples home and when put under the scope, am always amazed at the unseen life that can be found, such life, is of course, what makes a deep sand bed functional and worth having.
Let me know what you find, I always get a kick out of discovering new (to me) critters. Corals are cool and all, but I get the most enjoyment out of all the "little peaple" that make a reef, a reef. My dive buddies would always get mad at me when they would have to come back looking for me, only to find me with my face pressed into the reef watching all the little critters go about their business...lol Even now, I spend time each night using a flashlight to attract plankton so I can catch a few and put them under the scope, which is where I got all the photos from for
my zooplankton page.
