(a type of snail)
cannibal snail, rosy wolf snail

Euglandina rosea is one of the demonstrated predators on extant populations of Hawaiian tree snails. By 1958, Euglandina was found in Makaki Heights [Oahu] with dead Achatinella (Kondo, field notes [Appendix II, RPFTOTSOTGA 1993]), Since its introduction, Euglandina rosea has spread to low and high elevations throughout the Koolau and Waianae Ranges [Oahu] and has been the cuase of the local extinction of many populations of Achatinella (field notes of Hadfield, Kondo, Christensen, and Chung [Appendix II, RPFTOTSOTGA 1993]. Euglandina rosea was introduced to Hawaii between 1955 and 1956 by the Hawaii State Department of Agriculture in an effort to control the African snail (Achatina fulica). Euglandina rosea is a voracious predator on other terrestrial and arboreal snails and is responsible for the extinction of all eight species of the tree snail genus Partulaet al., 1988). Euglandina rosea follows mucous trails of other gastropods (Cook, 1985) and will climb trees and bushes to capture its prey.

The decimation of endemic Hawaiian tree snails by alien predators (abstract)
The alien predatory snail, Euglandina rosea eats all sizes of native Hawaiian snail Achatinella mustelina and can rapidly drive populations to extinction (American Zoologist, 1993).

Introduced plants and animals have played a role in the extinction of endemic land snails on Moorea (Philosophical Transactions: Biological Sciences,1992).
Slime-trail tracking in the predatory snail, Euglandina rosea (abstract).
Slime-trail tracking in Euglandina is a robust, easily measured and manipulated behavior that is a good model system for studying sensory processing and learning (Behavioral Neuroscience, 2003).
