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 smooth thick pear-shaped
with the spiral tip sticking out quite a bit, usually longer than
wide. Shell pattern white or beige with brown or black spots (more
of a leopard pattern than a tiger pattern). On
the underside, a small comma-shaped depression. Operculum white sometimes with a dark smudge where the whorl starts, sometimes small to large bright yellow patches, a pair of spiralling
grooves on the outer margin and finely serrated inner margin. Body mostly plain white or beige sometimes
with darkish edges, the fleshy area near the shell often with small
white spots. Tentacles short. |

Malaysia and Indonesia. |
