description Partula aurantia Overview

Partula aurantia was a species of air-breathing land snail belonging to the Partulidae family. This terrestrial gastropod was endemic to the island of Moorea in French Polynesia, where it lived primarily on specific host plants in forested habitats. The species became a subject of interest for evolutionary biologists studying genetic drift and adaptation in isolated island ecosystems. It was driven to extinction in the wild during the late 20th century following the introduction of the carnivorous rosy wolfsnail as a biological control agent.

help Partula aurantia FAQ

Is Partula aurantia extinct?

Partula aurantia was endemic to Moorea and is considered extinct in the wild. Conservation records distinguish it from related Partula species that survive in captivity or as remnant wild populations. [Peer-reviewed Partula conservation study](https://pmc.ncbi.nlm.nih.gov/articles/PMC6503832/)

What caused the decline of Partula aurantia?

The main documented threat was the introduction of the predatory rosy wolfsnail, Euglandina rosea, to Moorea. Habitat loss and changes to forest vegetation added pressure to a snail that had evolved only on that island.

Why are Partula snails kept in captive-breeding programs?

Several Partula species were rescued for captive breeding after introduced predators eliminated them from the wild. Zoos and conservation programs use those populations to preserve genetic lines and support carefully managed reintroduction efforts in French Polynesia.

Where did Partula aurantia live before it disappeared?

It lived in the forest habitats of Moorea, where Partula snails climbed vegetation and fed on organic material. Its island-restricted range made the species especially vulnerable to a predator introduced from outside French Polynesia.
