Samoana attenuata
Samoana attenuata is a tree snail in the family Partulidae (order Stylommatophora), recorded as Endangered.
Range and habitat
This species is endemic to French Polynesia.
The slender snail was widespread in Society Islands. But in the late 1980s, carnivorous Euglandina rosea was introduced into Society Islands and this led to Samoana attenuata snails disappearing quickly.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
Partula snails graze micro-algae and fungi on leaves at night. They do not recover once a predator snail is established on the island.
Snails move on a single foot and feed with a rasping tongue. Island and spring species rarely recolonise once the site is emptied.
In crisis
Populations on Raiatea were thought to be extinct until 2006.
The rosy wolfsnail and habitat clearing are the documented wrecking ball for Partula on Pacific islands.
