General Information

The Oahu tree snails are a classic example of the devastation of the native fauna and flora of the Hawaiian Islands that has occurred following human settlement of the archipelago. These small snails have a smooth, glossy shell, which is generally conical in shape. These nocturnal snails are found on native trees and large bushes, where they graze fungi from the surfaces of leaves and stems. Adults have both male and female parts (they are hermaphrodites) and give birth to live young. Oahu tree snails are today restricted to mountainous forests above 500 meters.
