Neverita duplicata Sand Egg Collar Shark Eye (Moon Snail)

    The sand egg collars (actually a mixture of mucus, sand and eggs) produced by the Shark Eye Moon Snail [six small living specimens are pictured] are a common fixture on the open Atlantic beaches of northeast Florida.  As the species produces these collars offshore in deeper water, they are usually only found washed ashore following heavy seas.
