Queen conch

Photo take a t -40 ft in a Caribbean reef.
Possesses a large conical shell with a flared lip which spirals to a point adorned with knobby spines. The orange to brown shell is often covered in encrusting algae, while the inside edge of the lip is a rich pink or orange colour. Small yellow eyes on stalks protrude from under the narrow end of the shell, and a yellowish horn on the end of the muscular foot is used for locomotion.
