Box turtles are the turtles most commonly thought of as pets. If you had a pet turtle, it was likely this kind. There are several different species in the U.S. and Mexico, all of the genus Terrapene. Even though they are commonly thought of as pets, although this is not recommended as they are easily stressed and require a higher degree of care than is usually recognized. They can live to be over 100 years old and so will likely out live their owners if they are well cared for.
