Coexisting with a turtle or tortoise may not be a warm and fuzzy experience, but it definitely has its rewards. And with more than 250 species to choose from, you're bound to find one that's right for you. Looks-wise, they can range from very plain and unadorned to a brightly colored and embellished with every manner of crest, crown, spike, and dewlap. As for personality, you'd be amazed at how very different they can be, ranging from shy and withdrawn, to outgoing and friendly, to outright aggressive. And when it comes to longevity, well, let's just say that when you commit to a turtle or tortoise, you're in it for the long haul. For example, the standard American box turtle can live more than 125 years, a leopard tortoise has a life span of up to 100 years, and an aldabran tortoise can live to be more than 200 years old!
