Batillariidae, common name batillariids or mudcreepers, are a family of marine, cerithioidean gastropod molluscs in the clade Sorbeoconcha.They consist of 14 living species, classified in six to eight genera. A revised generic classification has been suggested that is consistent with a molecular phylogenetic hypothesis. Accordingly, within the Batillariidae four genera Batillaria, Pyrazus, Velacumantus and Zeacumantus have been recognized. This delimitation of taxa is consistent with a revised definition of the family based on shell characters.
