== Miêu tả ==
This large snail is about the size and shape of an ice-cream cone! It is commonly seen in our mangroves, on mud, sometimes in the hundreds covering a large area. It is also called 'Rodong' or 'Berongan' in Malay.
Features: 8-15cm. The largest of our Horn snails, the heavy conical shell is actually beautifully marked but the patterns are usually hidden by mud and other encrusting animals. The outer lip is thin and not flared. Operculum small and circular. The animal is velvety black with a highly extendible proboscis. There is a third eye on its mantle margin, in addition to a pair of eyes at the tentacles. It can stay out of water for long periods of time.
What does it eat? Rodong sucks up detritus and algae from the mud surface at low tide, using its proboscis.
Human uses: It is eaten and is said to be delicious when steamed and eaten with chilli. It is gathered for food in Đông Nam Á and often sold in traditional markets.
