Evidence suggests that the Nile Soft Shelled Turtle (Trionyx triunguis) travels widely within the coastal waters of the Eastern Mediterranean, with many meeting their deaths in fishermen’s nets each year and one individual even turning up at the Greek Island of Kos. This paper seeks to gently provoke the sea turtle ‘establishment’ by arguing that this species provides a controversial ‘grey’ subject area between freshwater and marine habitats, and thereby is not only of particular significance with respect to our understanding the evolution of sea turtles, but also warrants the concern and attention of sea turtle conservationists.
