Mystery white cone shell from seller in Florida
I just spent $10 on this 4 inch (~100 mm) shell without identification from a seller in the Florida Panhandle. It is obviously real, as shown by the photos. What got me interested in this is the pronounced blue coloration around the siphonal canal. I had originally thought that this coloration was caused by pigments in the cone material (aragonite) but I'm leaning more toward the observation that aragonite can crystallize in a range of colors, including blue. This is a genetic trait as the deposition of calcium, caerbonate & other ions by the mantle are all controlled by the animal's DNA.
