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.〔Ozawa, T., Köhler, F., Reid, D.G., Glaubrecht, M. 2009. Tethyan relicts on continental coastlines of the northwestern Pacific Ocean and Australasia: molecular phylogeny and fossil record of batillariid gastropods (Caenogastropoda: Cerithioidea). ''Zoologica Scripta'', 38: 503-525.〕 According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Batillariidae has no subfamilies. However, a recent molecular study has found that the Batillariidae as traditionally conceived are not monophyletic. The Neotropical genera ''Lampanella'' and ''Rhinocoryne'' are sister to the Planaxidae. The monophyletic Batillariidae sensu stricto are restricted to the northwestern Pacific and Australasia.〔 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.〔 == Ecology and Distribution == Batillarids are abundant on sandy mudflats, and sometimes on rocky shores, on continental margins in the warm-temperate to tropical regions of the northwestern Pacific Ocean, Australasia and the Americas.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Batillariidae」の詳細全文を読む スポンサード リンク
