Siphonariidae, also known as false limpets, are a taxonomic family of small to medium-sized air-breathing sea snails, marine and brackish water pulmonate gastropod molluscs. Shell description Empty siphonariid limpet shells can be distinguished from true limpet shells by examining the interior. In the siphonariids there is a well-marked lateral groove on the right side of the shell, and a corresponding interruption of the ring of muscle attachment scars. These markers show the positioning of the pneumostome or pulmonary orifice.
