Eastern box turtle, I would say female, still pretty young, I'd vote around 10 years... Very protected in the wild. I would say read the care sheets and then ask any specific questions you have as it may be alot easier that way. Congrats though, she looks very healthy and I am assuming captive born. Consider before getting too attached though that they require a large amount of space and have been recorded to live over a hundred years! They're also very specific on their "home range" so moving them or rehoming them is VERY stressful
