Karkó is a musical instrument made from the karkó, a large clam species that lives in the bays of Bonaire, especially near Lac Bay. This musical instrument is also found on other islands and in the coastal areas of Central American and South American countries. It is almost certain that the karkó is a typical instrument of the Indians of Bonaire. During the harvest festival, the simadan, the karkó is blown. In the past it was also a means of communication to bring news.
