Map turtles are popular pets, because of their captivating and conspicuous appearance, and the Barbour’s map turtle is no different. These carnivorous turtles are good swimmers and spend most of their time in the water. The eye-catching markings and saw-like high-domed shells set map turtles apart from other turtles.

Barbour’s Map Turtle Facts and Information

The Graptemys barbouri is endemic to the southeast United States. They are riverine turtles and can be found in the Apalachicola River and its tributaries (including Chipola River) in the southwest of Georgia, the Florida panhandle and the southeast of Alabama.

These turtles prefer faster-flowing waters than most Emydidae turtles do. While adults prefer deep waters, the juveniles and hatchlings prefer to stay close to the bank.

The Graptemys barbouri belongs to the family Emydidae, and the genus Graptemys (which includes all other map turtles).  

While male turtles have a carapace (shell) length of 3.5 to 5.5 inches, females are much larger and have shell lengths of 5 to 12.5 inches. As with other map turtles like the texas map turtle, mississippi map turtle, and false map turtle, the Barbour’s map turtle has a raised back with saw-like spines. The scutes of their greenish shell have yellow c-shaped markings. Their skin is brown to black and has yellowish green strips.

The lifespan of these turtles is unknown. However, a member of the Graptemys barbouri at the Smithsonian National Zoological Park lived to be 31 years.

Barbour’s Map Turtle Diet

Barbour’s map turtles are carnivorous. In the wild, they feed solely on animal food. The food they feed on depends on their size. Juveniles and hatchlings feed on insects and larvae. Males feed on insect, larvae, small snails and clams.

Females are the largest members of this species and as such fed exclusively on large preys including mollusks such as clams and snails. They use their beaks to crush these hard-shelled mollusks and swallow them whole.

Smaller males can be fed aquatic insects, crustaceans, mealworms, pieces of fish and small mollusks. Larger females can eat clams and snails. You can also feed them with prawns, crayfish, and mussels, fiddler and green crabs, minnows, shiners, and periwinkles.

In addition to this protein-based diet, you can also feed them commercial turtle food. This can make up about a third of their diet. Two popular turtle foods suitable for your Barbour’s map turtle include Fluker’s Aquatic Turtle Medley Treat, and ReptoMin Adult Turtle Formula Sticks.

Barbour’s Map Turtle Habitat

The Barbour’s map turtle is a predominantly aquatic turtle. They are strong swimmers and can swim in fast-moving rivers. These aquatic turtles will come out to bask on logs in the river/stream they inhabit.

Because of their bashful nature, they usually dive back into the water at any sign of danger. They spend almost all their lives in the water and only come out to nest.

As with all map turtles, a large turtle tank is important. The water capacity of the turtle tank should be between 75 to 120 gallons. This gives the turtle a lot of room to swim.

Apart from tanks, these turtles can also be housed in koi ponds and turtle tubs. Regardless of where they live, a basking area is important. For males, commercial turtle basking docks will do.

Females can grow over a foot long and generally need a larger area to bask. You can create a basking area using slates of rock as well as natural cork bark.

When housed in turtle tanks, a pump and filter are necessary to keep the water clean. It is important that the filter is powerful enough to properly keep the tank spotless. Even with a pump and a filter, you still need to replace a third of the water in the tank once a week.

Good lighting is important when it comes to caring for pet turtles. Since the side glass of most aquariums and turtle tank filter out UVB light from the sun, you will need to provide this important rays yourself with the help of UVB light bulbs. This light should be above the basking spot.

The temperature of the enclosure needs to be properly monitored. The basking spot needs to be 85 degrees to 90 degrees, while the water temperature should be around 75 degrees.
