Head found in the anterior part of the circle while the peak (spiral) is the back (posterior) on the right side. The outside of the shell is rather rough and smooth while the inner layer of nacre looks even some colorful species. On the left side of the shell there are small holes lined. Larger holes on the front and back to smaller and more closed. Normally open hole number five, this hole serves as the entry of water containing oxygen and release carbon dioxide discharge even egg cells and sperm as well to prose respiration and excretion of wastes. Shell growth occurred with the addition of the front on the right side.
