Where seen? This conch with wavy lips is sometimes seen
on sandy shores and near seagrasses.
Features: 3-5cm long. Shell thick heavy, lip slightly flared. Sometimes with a low ridge on side
opposite to the flared lip.
Upperside smooth with a pattern of brown bars, sometimes plain, sometimes covered with encrusting organisms. Shell opening pearly white. Body mottled. Large eyes on
eyestalks, each eyestalk has a tentacle, the purpose of which is not known. Like other conch snails, it hops using the knife-like operculum at the tip of a long muscular foot. |
