Taxonomy
editThere are two subspecies of T. ornata:
- Ornate box turtle, Terrapene ornata ornata (Agassiz, 1857)
- Desert box turtle, Terrapene ornata luteola (Smith & Ramsey, 1952)
Description
editT. ornata has a shell that is less domed than other species of box turtle, appearing to be slightly flattened. Their coloration is generally black or dark brown, with yellow striping. T. o. luteola tends to have more striping than T. o. ornata.
T. o. ornata are generally more bold in their approach to predators, often stretching their legs and head out in an attempt to look big. T. o. luteola are more likely to close up into their shell and utilize their hinged plastron as protection.
Both sub-species, although they live in dry, arid environments, will dig deep burrows to escape the heat and allow access to higher humidity content.
Range
editT. ornata ornata is found in the central United States from western Indiana, to eastern Texas, and into Louisiana; it can also be found in Northeastern New Mexico. T. ornata luteola inhabits the driest areas of all the box turtle species, and is found in western Texas, New Mexico, Arizona, and adjoining areas of northern Mexico.
Conservation
editIn Indiana, the ornate box turtle is listed as an endangered species.[4]
Symbol
editThe species became the official state reptile of Kansas in 1986.[5][6]
