Fat Guam partula
Partula gibba
Fat Guam partula is a tree snail in the family Partulidae (order Stylommatophora) — Partula gibba, recorded as Endangered.
Range and habitat
This species occurs throughout the Mariana Archipelago, and has been reported in the greatest densities and population sizes on the isle of Sarigan.
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.
