The tree snail

Partulid tree snails are Pacific island endemics. Predatory rosy wolfsnails, introduced to control other snails, emptied island after island.

These are the familiar land snails and slugs: air-breathing gastropods with a lung, not a gill.

Range and habitat

This species is endemic to American Samoa.

GBIF currently lists 216 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.

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.

Samoana conica is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
