Tiger moon snail
Notocochlis tigrina
Family Naticidae
updated Oct 2016
Where seen? This moon snail with a spotted shell is sometimes seen on our sandy Northern shores near seagrasses. Undisturbed shores may have large numbers of them. It was previously known as Natica tigrina.

Features: 2-3cm. Shell thick pear-shaped with the spiral tip sticking out quite a bit, usually longer than wide. Colour white or beige with brown or black spots. (It is more of a leopard pattern than a tiger pattern). Operculum shelly, smooth with two grooves on the outer margin, white sometimes with bright yellow or black patches. Large foot mostly plain white or beige sometimes with darkish edges, the fleshy area near the shell often with small white spots.

Human uses: Where it is abundant, it is collected for food and the shell trade, especially in Japan, Malaysia and Indonesia.
