Gold-ring Cowrie
Monetaria annulus
Cowries are amongst the most beautiful of marine snails. They keep their thick shell clean and polished by covering it with a thin fleshy mantle that can be retracted back under the shell when disturbed. The Gold-ring Cowrie grows only to about 30 mm long, and is abundant on eel grass flats in sandy-mud or sand, from the intertidal to the shallow subtidal zones, and in pools on ocean reef platforms.
Common across northern Australia and throughout the Indian and West Pacific Oceans.
