I like coral reefs. But I also like the sand next to them – there is a good amount of unusual marine life. Things are more subtle. You can’t be all colorful and striking if you plan to survive in the sand. Camouflage and motionlessness, or digging yourself into the sand, or be very small, or dig a burrow, or all of the above, are the ways of the sand-dwellers among the marine critters. There is something uniquely aesthetically pleasing about discovering a diverse fauna in what at first seems like a barren zone.
