Family Naticidae

Moon Snails

Moon snails are nocturnal sand dwellers that prey upon gastropods and bivalves by drilling a perfectly round hole through the shell and liquefying flesh with acidic saliva.  Many micromollusks are found with holes, attesting to the success of moon snail predation.  Females deposit thousands of tiny eggs using a mucus ribbon, forming a multilayered sand collar that disintegrates after hatching.
