Euglandina rosea (Férussac, 1821) Rosy Wolfsnail Cannibalism

   This 68.0 mm. shell with a freshly deceased animal was found in the roadside swale on the west side of US-1 about 3.2 miles northwest of International Golf Parkway, St. Johns County, Florida on 1/31/2020. It was found shortly after heavy equipment was employed to mow vegetation in the roadside swale and the specimens demise was initially believed to be related to that event. However, later when dissected, it was discovered that most of the animal was missing and thus cannibalism is likely the reason for the specimens demise. The bottom image shows the shell after cleaning and remaining animal extraction and no damage to the shell itself is present. During dissection two fresh juvenile Polygyra septemvolva Say, 1818 Florida Flatcoil snails were discovered in its gut. Also see: Euglandina rosea Predation On Polygyra septemvolva Say, 1818.
