Pyramid Turbo Snail

Turbo snails carry a heavily calcified operculum known in the shell trade as a "cat's eye" — beachcombers collect them as jewelry long after the snail itself is gone. On a living animal it's a hatch that seals the shell shut tight against predators, backing up one of the strongest, most tireless algae-grazing engines you can put in a reef cleanup crew.
