Clear Sundial Shell

Clear Sundial Shell Art on Canvas in a Black Bijou Frame. Sundial Shell also called Winding-Staircase Shell or Perspective sundial shells. The shells are distinctively disc shaped being round with a broad flat base and flattened spire which curves clockwise from above. There are three continuous brown and white bands which follow the spire They grow up to 6 cm in diameter. Viewed from above the circular shell with the alternating white and brown bands resembles a sundial giving them their common name. The mollusk its self is white with black edges and they are shy and do not appreciate light being put on them. Sundial shells are common across the Indo-Pacific area and are reportedly more common from 30 meters to 50 meters in depth If you are a conchologist (collector and student of shells) we would love to hear from you about how you would improve this description.
