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. The name "Helicinidae" immediately reminds most people of "Helicidae", the most popular group of land snails including e.g. Helix pomatia, but the important two letters "ni" only from the Latin diminutive of the latter name alluding to superficial similarities of otherwise completely different things.

Distribution edit

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. Some species are found in the southern United States, from Louisiana to Florida; others in Central and South America.

Taxonomy edit
