Diversity[1]
770-1400 species (estimation)

These snails are not at all closely related to the air-breathing land snails, despite a superficial similarity of the shells.

Distribution

These snails are found in tropical and subtropical areas but they have an odd distribution: they are restricted to the Caribbean islands and some Indo-Pacific and Pacific islands, as well as the edge of the Asian and Australian continents.

Taxonomy

Helicinidae belongs to superfamily Helicinoidea according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).[2]
