Partula otaheitana
Partula otaheitana is a tree snail in the family Partulidae (order Stylommatophora), recorded as Endangered.
The tree snail
Partula tree snails live on Pacific islands. A live animal is a few centimetres of shell on a leaf; a lost island population is usually gone for good.
Partulid tree snails are Pacific island endemics. Predatory rosy wolfsnails, introduced to control other snails, emptied island after island.
Range and habitat
This species is endemic to the island of Tahiti, French Polynesia, where it was formerly widely found in the valleys but is now restricted to the highest altitudes.
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
The rosy wolfsnail and habitat clearing are the documented wrecking ball for Partula on Pacific islands.
