Euglandina rosea (Férussac, 1821) Predation - Gut Contents

    When the intended prey of a Euglandina is large, it often extracts its victim from the shell without actually swallowing the shell. However, the more common method is for the species to actually swallow the prey along with its shell. The 24 mm. Euglandina rosea illustrated below was collected along International Golf Parkway in northern St. Johns County on 10/11/2009 and later dissected. The seven shells shown below were found in its gut - all of which appear to be Polygyra species (P. cereolus or P. septemvolva) which are common in the area where the Euglandina was collected. The specimen was somewhat of a glutton as compared to other specimens that have been dissected.
