Where
seen? This flat moon snail is sometimes seen on our Northern
shores among seagrasses. Elsewhere, they
are found in deeper water and considered uncommon. Mamma means 'breast' in Latin.
Features: 1.5-3cm. Shell thin,
flat with three broad bands of dark brown stripes. On the underside, a dark chocolate
brown lip. Operculum is made of a thin horn-like material, orange
or brown. Body plain white. When alive, the body is much larger than the shell, usually enveloping the entire shell making it hard to see the shell. |
