During the monsoon season (from September to March, annual year), the coast of Con Chay Muoi, District Binh Dai, Ben Tre province, Viet Nam is covered with millions of turritella shells.. These turritella are 7-8cm long, after a journey at sea, drift to the sun and die, their bodies spread along the 7km coastline of Thoi Thuan commune.
