Abstract

During a study of an Iberian population of the European pond turtle, Emys orbicularis, a very high number of water lily seeds, Nymphaea alba, was found in fecal samples. Further analysis of additional samples collected between 2003 and 2008 indicated that E. orbicularis uses water lilies as an emergent food resource during summer. It is proposed that E. orbicularis should no longer be viewed as strictly carnivorous.
