Most divers go for the rocky terrain, and why not? Lots of nooks and crannies for things to hide in, and good attachment surfaces for the more sessile marine dwellers. But this fellow I found in the open sand. This is a little cuttlefish (Sepiola atlantica) which was hiding in the sand until I disturbed it. To give some sense of scale, he is about the length of my thumb.
This is him in action.
