How old do green snakes live?

Green snakes, particularly the Eastern Green Snake (Opheodrys vernalis) and the Rough Green Snake (Opheodrys aestivus), typically live around 5 to 10 years in the wild. In captivity, with proper care, they can live longer, often reaching up to 15 years or more. Their lifespan can vary based on factors such as habitat, diet, and predation pressures.
