Zebra moon snail
Tanea areolata
Family Naticidae
updated Aug 2020
Where seen? Sometimes seen on our Southern shores, this fast moving moon snail is seen near coral rubble and living reefs. It was previously known as Natica areolata.

Features: 2-3cm. Shell smooth thick spherical (not flat) with the spiral tip sticking out a little. Shell pattern brown with spirals of white zig-zag lines. On the underside, a small circular depression. Operculum plain pearly white with a yellow smudge where the whorl starts, a pair of spiralling grooves on the outer margin. Foot plain white with a dark bar on the back portion, the front portion beige with three white bars. Tentacles short, white with dark tips.

Snail takeaway? Some have been seen 'dragging' a small snail shell behind them attached to the foot. Is it taking the meal away to some other place to eat it in safety?
