Fun Animal Encounters

From a hairy tarantula to a talking African gray parrot, you never know what you’ll bump into in Ranger Rick's Backyard Safari at the Tennessee Aquarium!


Barbour's Map Turtle

Graptemys barbouri

ON EXHIBIT:  Delta Swamp at River Journey.

Barbour's Map Turtle

 Male Barbour's map turtles only grow to 5.5 inches (14 centimeters) while females grow to 12.5 inches (31.7 centimeters). A difference in the size or shape of male and females of the same species is called sexual dimorphism. In this species one of the benefits of the size difference is that males and females feed on different prey so there is no competition between the two.

IUCN: Lower Risk/Near Threatened. The greatest threat is the rapid degradation and alteration of habitat in and adjacent to the rivers of the southeastern United States.
