Rosy Wolfsnail
Euglandina roseaAlso known as Cannibal Snail
Rosy wolfsnails are voracious predatory gastropods that track other mollusks across the forest floor by following their chemical slime trails. Equipped with elongated, mustache-like labial tentacles, they locate and swallow smaller snails whole or rasp into larger shells with a razor-sharp radula. Deliberately introduced to tropical islands as a biological control agent, their aggressive feeding habits severely decimated native island tree snail populations instead.
