Horned helmet snails feed on sea urchins. The snails are easy to spot once you know what to look for, a shape in the sand. The snail may appear like an abandoned shell on first examination, the top covered with algae. It is the size that is surprising, these snails are huge, the shell well over a foot long and almost as much in diameter.
