Shark Eye Moon Snail. The Shark Eye snail is a carnivorous snail in the moon snail family. It has a foot that it uses to search for food, when it finds another mollusk or clam the Shark Eye rolls it up in its foot and uses a radula to make a hole and eat it. This one isnt moving because it has a hermit crab in it instead. I flipped it over for a quick photo then back onto its feet and left it be. I dont know enough to tell what kind this hermit crab is because it wouldnt come out of its shell.
