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]
