Euglandina rosea, common names the rosy wolfsnail or the cannibal snail, is a species of medium-sized to large predatory air-breathing land snail, a carnivorous terrestrial pulmonate gastropod mollusk in the family Spiraxidae.
This species is a fast and voracious predator, hunting and eating other snails and slugs. The rosy wolfsnail was introduced into Hawaii in 1955 as a biological control for the invasive African land snail, Lissachatina fulica. This snail is responsible for the extinction of an estimated eight native snail species in Hawaii. This has caused the snail to be added to the IUCN’s top 100 most invasive species.
