Euglandina rosea (Férussac, 1821) Rosy Wolfsnail

Euglandina rosea (Férussac, 1821) Rosy Wolfsnail - Large Specimen

On 2/24/2008 this large (57 mm.) Euglandina rosea shell was discovered in ornamental vegetation alongside State Road A1A on Amelia Island, Fernandina Beach, Nassau County, Florida. Interestingly, inside the Euglandina shell were two empty Polygyra cereolus (Mühlfeld, 1816) [Southern Flatcoil] shells. There are several possibilities to explain the presence of the Polygyra. These include ta scenario in which the duo entered the empty Euglandina shell to scavenge calcium carbonate or simply to seek shelter and died in situ and one in which they were eaten alive by the Wolfsnail, which expired shortly afterwards with their remains in his digestive tract. Despite the presence of a healthy and diverse population of potential prey species to include the aforementioned Polygyra, Succinea campestris Say, 1818 [Crinkled Ambersnail] and the large exotic Otala punctata (Müller, 1774), this is the first Euglandina rosea (dead or alive) to be found at this location.
