This is a conch shell. Inside is the conch, which is a general term for a large sized, sea snail with a shell that comes to a clear point at the end. This specific conch is part of the strombidae family which is usually referred to as a “true Conch”. Conch is a common food in the Cayman islands and is used to make stews, chowders, fritters, ceviche, and sometimes burgers. The conch has a large nail at the end of their foot that allows them to grip the sand and slowly move them along the sea floor. They are herbivores so they survive on sea grass and algae.
