Range follows the Pearl River system from central Mississippi southward along the border of Louisiana to the Gulf of Mexico.
This turtle prefers moderate to swift-flowing water in wide sections of river with lots of logs and sandbars for basking in sunny areas.
This species is named for the distinct light rings present on its pleural and marginal carapace scutes. The central carapace scutes on juveniles have tall, pointed peaks, which become dull and less pronounced with age. The background carapace color is brown to green, and the rings are usually yellow. The rings on the marginal scutes are often incomplete, and the posterior marginals are serrated. Its skin is dark black with yellow stripes and markings, including a spot behind each eye, and a "chin-strap" across the lower mandible. Its plastron is mostly yellow with variable, irregular dark markings along the seams. Males are smaller and average 3-4 inches in straight carapace length, while females average 5-8.5 inches.
