Critically Endangered
Crampton's Partula Tree Snail
Partula cramptoni
Crampton's Partula Tree Snail is a tree snail in the family Partulidae (order Stylommatophora) — Partula cramptoni, recorded as Critically Endangered and tied to Solomon Islands.
Appearance
It is significantly larger and more massive than the other species in the region and is characterized by its very dark brown color, that differs significantly from the light yellowish shells of the smaller species.
Range and habitat
Crampton's Partula Tree Snail is an endangered species of terrestrial lung snail from the family Partulidae, that is now only found on the Solomon Islands of Bellona. The previous population from Rennell Island is now extinct. Crampton's Partula Tree Snail is one of the most striking species known from the Solomon Islands.
GBIF currently lists 18 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.
