These predatory snails were introduced to Hawaii in an attempt to eliminate the giant African land snail. However, they also attacked the O`hau tree snails. As a result many tree snail species were hunted to extinction within the first year. These snails are still a threat to the local snail fauna.
In appearance the rosy wolfsnail has a light brown long spiraled shell and a light grey, or brown body. It can grow quite large compared to most snails, and its lower tentacles seem to almost drag on the ground.
This species is a voracious predator, preying on other snails and slugs. The smaller species of snail that it eats are ingested whole. This gave it the nickname "the cannibal snail".
