This Snakehead Cowry is partially covered with its mantle. The mantle can cover the entire shell. The mantle secretes layers of shell from the outside making cowries very shinny. The mantle aids in camouflage and respiration. The appearance of the mantles of different cowry species varies greatly. Amami 2018
