Abstract
The territory of the Poleski National Park is one of the most populous stands of pond turtle Emys orbicularis (L., 1758) in Poland. In the turtles one can observe deviations from the typical structure of the shell, usually in the form of extra scutes or absence of typical scutes. The objective of the study was to estimate the kinds of anomalies and the frequency of their occurrence in European pond turtles from the hatch of 2008, kept at the European Pond Turtle Protection Centre at the Park facilities. In total, 441 individuals of the turtles were kept at the Centre, among which in 69 individuals (15.6%) carapace anomalies were found, and in the case of certain indi-viduals several kinds of anomalies occurred simultaneously.
