One of the assumptions refers to a threat toward our native amphibians. Feeding habit Only the juvenile turtles are mainly carnivorous and hunt for snails, fish, amphibians, and waterbugs. A protein-rich diet ensures a rapid growth. Research in the USA revealed that adult Trachemys are not specialized fish hunters, although sometimes they will try to get them. Mature turtles generally feed on water vegetation and water insects.
Turtles also feed on sick or dead fish or other animals.
Conclusion Trachemys s. elegans is an adaptable reptile which is able to survive even outside its natural range in other climate zones with harsh winters and relatively cool summers. The species does occur in the wild in The Netherlands, but can't be considered common. In The Netherlands, feral Trachemys should not be considered a serious threat to flora and fauna. Fortunately, the European Community just executed a legislation which prohibits the importation of red-eared sliders in European countries. The motive for this act was that this turtle is considered a threat for native flora and fauna.
