Partula taeniata


Partula taeniata, common name the Moorean viviparous tree snail, is a species of terrestrial gastropod in the Partulidae family. It is endemic to French Polynesia.
This species was considered to be extinct in the wild, but intensive field surveys have recently detected surviving wild populations.

Conservation status

The species is listed as Critically Endangered in the 2022 and 2024 IUCN Red List of Threatened Species.
Previously it was incorrectly listed as extinct on the IUCN Red List of Threatened Species from 1988 to 1994 and as Extinct in the wild in the 1996 IUCN Red List, before being corrected to Critically Endangered in 2009, although two subspecies survive in captivity and one still exists in the wild. This error may be the result of changing taxonomy.
In 2010, a single Partula taeniata spp. simulans was transferred to the Edinburgh Zoo; the subspecies now has several hundred individuals surviving in captivity.
