Family Turritellidae
updated Oct 10

Where seen? Only the elegant shells have been seen on our shores so far. The living animal has yet to be encountered on the intertidal. The empty shells seen are usually occupied by a hermit crab. Elsewhere, they are found on soft bottoms.

Features: Those seen 5-7cm, can grow to 15-17cm long. Elegant shell with regular spirals which are finely ridged. It is herbivorous and lives on sandy and muddy areas of the intertidal zone.

Human uses: In the northern Philippines, they are regularly collected and marketed as food.

Status and threats: Turritella terebra is listed as 'Vulnerable' in the Red List of threatened animals of Singapore. In the past it was abundant before its habitat was reclaimed.
