Family: Turbinidae (Turbans & Star Shells)


Generally, these are strong shells with a  nacreous aperture and a calcareous operculum. In all, the aperture opens to the side, looking from the top. Most are conical in edgewise appearance. The strikingly flattened appearance of the Yoka Star Turban species, with its very long hollow spines, is somewhat exceptional. 

Most turbans are found in warm waters near coral reefs. In the Collection, size varies to six inches or more.
