5 Large Turtle and Tortoise Species People Keep as Pets

What are the largest turtle species?

Enthusiastic reptile owners often like to step up their game by relocating their indoor terrarium to an outdoor backyard enclosure. But as you can imagine, such a large space wouldn’t suit small turtle species like Spotted or Mud turtles. In this article, we’ll recommend 4 of the largest types of turtles that you can nurture in your backyard.

Biggest Turtles

Pet turtles may not always reach the same size as exceptional wild individuals, but they still need to be housed as if they will reach full adult size.

Not all large turtles can be kept as pets, at least not in a conventional manner.  And while you can’t keep these turtles at home, there are some decent-sized turtles (or tortoises) that you can, so let’s check them out.

1. Sulcata Tortoise

For the top spot, it’s hard to beat the Sulcata tortoise. Also known as the African spurred tortoise, this species can grow to around 24 to 30 inches long and often weigh well over 100 pounds, making it one of the largest tortoises commonly kept as a pet. They may start out small, but they do not stay that way for long, so owners need to plan for an adult-sized animal from the very beginning.

Because of their size and strength, Sulcatas need a large, secure outdoor enclosure rather than a typical indoor setup. They love to roam, graze, and dig, so fencing needs to be sturdy, high enough to discourage climbing, and buried into the ground to help prevent escape. These tortoises are powerful burrowers and can do a surprising amount of damage if their enclosure is not built properly, which is why they are best suited to keepers who have plenty of space and are ready for a serious long-term commitment.

2. Pond Sliders

Pond sliders are some of the most common large pet turtles, with the term usually referring to species like the red-eared slider and Cumberland slider. They have a classic turtle look, with smooth olive-to-green shells, yellow striping, and a streamlined shape that makes them excellent swimmers.

While young sliders may look small and manageable, they can grow much larger than many first-time owners expect. Adults often reach 8 to 12 inches long, with females usually growing noticeably larger than males. Because of that, they need far more room than the average small turtle setup can provide.

The good news is that pond sliders are generally hardy turtles, but they still need proper care to do well. A large aquatic enclosure, clean filtered water, a basking area, and consistent heating and UVB lighting are all essential. They can make great pets, but only for owners who are prepared for a turtle that will need a roomy setup and regular maintenance for years to come.

3. African Sideneck Turtles

African sideneck turtles are a popular choice for people who want a turtle with a slightly unusual look. They get their name from the way they tuck their heads sideways under the shell instead of pulling them straight back like most other turtles. Adults can grow to around 7 to 12 inches, which makes them a fairly large option for someone looking beyond the smallest pet species.

These turtles are mostly aquatic, so they need a roomy tank with clean water, steady warmth, and an easy place to climb out and bask. They are generally hardy when kept in the right conditions, but they still require more space and stronger equipment as they grow. For owners who want a larger aquatic turtle that is interesting to watch and not too difficult to care for, African sidenecks can be a very solid choice.

4. Leopard Tortoise

If you want a large tortoise that is a little more manageable than a sulcata, the leopard tortoise is a great species to consider. Adults commonly grow to around 18 to 24 inches long, and their beautifully patterned shells give them one of the most striking appearances of any pet tortoise. They have a calm nature and can make a very impressive long-term pet for someone with enough space.

Even so, leopard tortoises are not a small commitment. They need a roomy enclosure, warm conditions, and a diet built around grasses and other high-fiber foods to stay healthy. They also do best with owners who are prepared to care for a large tortoise for many years, so they are a better fit for people who want a serious long-term pet rather than something easy to keep.

5. Eastern Box Turtles

Eastern box turtles are one of the most recognizable turtles in the pet world, thanks to their high-domed shells and bright yellow or orange markings. They usually grow to around 5 to 7 inches long, so while they are not as massive as some other species on this list, they are still much larger than many people expect when they first see a young one.

Unlike fully aquatic turtles, eastern box turtles need a mostly land-based setup with warm temperatures, steady humidity, and access to shallow fresh water for soaking. They can be rewarding to keep, but their care is a little more involved than many beginners assume. Because of that, they are usually a better fit for owners who are ready to put time into creating the right environment from the start.
