Ringed Map Turtle
Bright yellow shell rings and a narrow Pearl River range make this small map turtle one of Mississippi’s most distinctive river specialists.
Artwork inspired by Andrew Bucci
Ringed map turtles occur only in the Pearl River system of Mississippi and Louisiana. They favor flowing channels with abundant basking logs and feed largely on aquatic insects and other river prey. Females grow larger than males, while both carry yellow ringlike markings that can fade with age.
Channel modification, snag removal, water pollution, altered flow, illegal collection, and basking disturbance all affect the species. The fastest way to ruin a sighting is to approach a log directly: map turtles drop into the water at long distance. Scan downstream with binoculars and let sunlight reveal shell markings.

Field marks for Ringed Map Turtle
- First clue
- Read yellow rings on an olive shell when identifying Ringed Map Turtle.
- Confirm with sign
- Compare flowing Pearl River channels together with females much larger than males before accepting the identification.
- Where it belongs
- Use Flowing Pearl River channels in Pearl River system, Mississippi as habitat context and check the appropriate active season.
- Observe without pursuit
- Protect the subject: Watch from a bridge, bank, or boat at long range and avoid repeatedly flushing turtles from basking logs.
Good to know
Map turtles can vanish from a log before an observer notices them. Use binoculars, keep boats slow near basking structures, and distinguish a genuine Pearl River animal from pet-trade photographs or similar map-turtle species.
