The Rosy wolfsnail, Euglandina rosea, is, relatively speaking, a fast and active predatory snail. Specifically, it hunts other snails and slugs. Native to much of Central America and the American southeast, the Rosy wolfsnail can wreak havoc in other regions where it is introduced. These puppies like to eat, and they’re pretty damn good at tracking and taking down other snails and slugs. They’re been particularly problematic in Hawaii.
