Black Wood
Black wood turtles are found in Central America, specifically in Panama, Nicaragua, Honduras, and Costa Rica. They thrive in areas near water bodies, such as swamps, marshes, rivers, and ponds.

To replicate their natural habitat, you'll want to provide a dry surface for your pet black wood turtle to walk on. A large container of water is also essential, with a depth that allows the turtle to submerge.
In their tropical environment, black wood turtles require a warm and humid enclosure. If your locale is warm and humid enough, you can even keep them in an outdoor enclosure.
Here's a rough guide to their size: black wood turtles can reach lengths of up to 14 inches.
