Keywords: black turban snail
Abstract: 1. Shell is erosion is caused by the activities of several animals (bryozoans and polychaetes), by mechanical wear, and by a fungus, which was cultured on agar plates. 2. Normal shell growth, recorded over a period of 15 days in 28 animals, was intermittant, but averaged 6 microns per day added to the outer lip of the aperature. 3. Repairs to shells damaged mechanically, by filling the aperature, grinding holes in the body and upper whorls, and by cracking in a vise are described.
