Where seen? The delightful living snail was seen only once
on Pulau Hantu although empty shells are sometimes seen on other shores.
Elsewhere, it is considered moderately common and usually found subtidally
on sandy and muddy bottoms, from depths of 10 to 120m, mostly between
10 and 65m.
Features: 5-6cm in diameter. An
unmistakable snail, the shell coils form a flat disc-shape with a
flat base. The shell is beautifully banded in shades of black and
brown. The body is striped too, to match the shell. The operculum
is made of a horn-like material. More about the Family
Architectonicidae to which this snail belongs.
Status and threats: The Clear
sundial snail is listed as 'Endangered' in the Red List of threatened
animals of Singapore. The original shores where they were found have
been lost to reclamation. |
