 Where 
            seen? Only the empty 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.
