Free Floating Mollusk

size: 1 3/4 inch

This marble is from my “Mollusk Series”  It is very hard to photograph the amount of organic detail and color in this marble.  Deeply reticulated tissues, frilly gills or perhaps feeding apparatus, translucent membranes.  Is it a member of the Giant Clam family?  Or perhaps a stage in evolution between a shelled mollusk and a jellyfish?  There is lots to explore inside this sphere.
