Central slice of a Bursa Bubo seashell
Giant Frog shell This architectural sculpture look like the cut of a spiral staircase. It is the heart of a very large shell called Bursa Bubo or Tutufa Bubo. On the Maldive islands it is nicknamed "Giant Frog shell". This very large snail found in the Indo-Pacific area is rather voracious and does not hesitate to eat starfish. The structure of its spirals is really very elegant. On brass base.
