I have in my mind taking some shots of crabs at a local beach. For the shots I envision this will mean lying prone in the sand and keeping the camera as low as possible to get the effect I want. Which obviously means the camera is also basically going to be rolling around in the sand with me. And because the little mongrels are people shy I'll also be shooting with my Nikon DLSR and 80-200mm F/2.8 AF-D lens.
Or are there other options that I am not aware of?
I am aware of this question: shooting-on-the-beach-is-it-dangerous-for-my-equipment and I am taking the approach of Take your camera but take good care of it, but what I am looking for is explicit, practical advice of how to go about doing this in my case.
