Diet

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

From 1983 to 1995, the general population of Partulina redfieldi grew significantly from 100% to 900%. Since 1995, the population has decreased by 85%, due to rat predation, that has shown itself to be a growing threat to tree snail species endemic to Hawaii. Partulina redfieldi population initially decreased by 85% within just 2 years of being discovered by rats.

Partulina redfieldi 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.
