The genus Deirochelys is represented solely by the chicken turtle (Deirochelys reticularia), a species native to the southeastern United States. This genus belongs to the family Emydidae, commonly known as the freshwater marsh turtles, and is characterized by its distinctive long neck, which can be nearly equal in length to its shell. The name “Deirochelys” derives from the Ancient Greek words for “neck” and “tortoise,” reflecting this notable feature.
