Batillariidae are a family of marine snails that includes 14 recent species in six to eight genera .
Taxonomy and systematics
In the current, preliminary classification of snails, this family is not further divided into subfamilies. The Pyrazidae Hacobjan, 1972 and the Tiaracerithiinae Bouniol, 1981 are considered synonyms .
According to the latest findings, which are based on the analysis of molecular and morphological features, the Batillariidae are not monophyletic as currently delimited . The Neotropical genera Lampanella and Rhinocoryne are sister groups of the Planaxidae . The monophyletic Batillariidae sensu stricto are restricted to the northwestern Pacific and Australasia .
Ecology and diffusion
Batillaridae are widespread in warm-temperate and tropical coastal areas of the Northwest Pacific , Australasia and North and Central America . There they are usually found in high population densities in suitable habitats . They inhabit the tidal range and live on muddy, sandy and stony substrates.
Fossil evidence and biogeography
The first fossils that can be assigned to the Batillariidae in the broader sense have been passed down since the Upper Cretaceous or the Paleocene . Since their origins in this time, the now extinct genera Pyrazopsis , Vicinocerithium and Granulolabium have spread along the coast of the Tethys . There they came in a variety of forms before becoming extinct in Europe at the end of the Miocene . Around the late Oligocene , the ancestors of the recent Batillariidae reached Australia and New Zealand . The family is represented in this area by three genera still alive today : Pyrazus , Velacumantus and Zeacumantus . Two groups, Batillaria and the now extinct genus Tateiwaia , reached the coastal areas of East Asia ( China , Vietnam and Japan ) further north in the early Miocene , where they can still be found today. Since then, the Batillariidae have had a disjoint distribution in the Indo-West Pacific .
