Shells that fluoresce by Shawn Miller.
Caught for human consumption, use in traditional medicine and linked with many superstitions. Shells were highly prized by private collectors till the 1950's and are now used as currency, ornaments and charms.
An interesting feature of most all taxa in the L. mappa complex is the visible red fluorescence emitted by the shells when illuminated by longwave ultraviolet (UV) light of around 400 nanometers wavelength.
