   With beautiful yellowish rings accenting its shell, the Ringed Map Turtle is quickly and easily recognized!

   The Ringed Map Turtle is one of the smaller so called 'Sawback' map turtles. The term 'sawback' is attributed to three (and possibly a fourth) of the map turtles species. They are designated as sawback map turtles because of their extremely accentuated scutes going down the center of their carapace, the vertebral keel. The rear of these vertebral scutes, especially the first three, strongly juts upward creating a serrated or saw-like appearance. The Ringed Map Turtle is very similar to the Yellow-blotched Map Turtle G. flavimaculata, except it has a yellow ring around of each its scutes rather than a blotch, to accent its otherwise olive brown body with a bright touch of yellow.

   Being fairly easy to take care of, the Ringed Map Turtle is good for beginners. It is very shy and alert, plopping into the water at the approach of its keeper. However it will soon become tame, and though it will still dive off into the water it will quickly re-surface to see if any food has been offered. An avid basker and active swimmer, it is a joy to observe.

   The Ringed Map Turtle can make a good companion in a community habitat as long as there is plenty of space and lots of decor. It can be kept with other map turtles as well as other baskers such as sliders, cooters, and painted turtles. However when kept with other turtles, it is important to add add an extra basking spot or two to the environment, and to avoid crowding.

  • Order: Testudines
  • Family: Emydidae
  • Genus: Graptemys
  • Species: oculifera

Distribution:    The Ringed Map Turtle or Ringed Sawback Turtle Graptemys Flavimaculata was described by Baur in 1890. They are found in the found in the Pearl River system in Mississippi and Louisiana where the current is moderate, the bottom is sandy or muddy, and there are numerous basking spots among logs and driftwood jutting out of the water.
   There are a twelve species, and several subspecies, of map turtles in the Graptemys genus. They are all found in the central and eastern United States and into southern Canada, generally in clear fast-flowing rivers and nearby ponds and lakes. The greatest concentration of these turtles are in the river systems of Mississippi, Louisiana, Alabama, and Florida.

Status    The Ringed Map Turtle is an officially endangered species in the United States: U.S. Endangered Species Act, May 4, 2004. They are also listed on the IUCN Red List of Threatened Species: EN - endangered, and list on CITES: Appendix III.

Description:    The Ringed Map Turtle has an olive to brown body highlighted with beautiful yellow ring on each of its scutes and a yellow undershell or plastron. It is one of the 'sawback' map turtles, having a serrated appearance due to extremely accentuated scutes along its vertebral keel, with the rear of each of these vertebral scutes projecting strongly upward.
   Adult map turtles have muscular heads but they have two distinct appearances, those that are 'broad-headed' (primarily for cracking mussels and snail shells), and those that are 'narrow-headed' designed more for eating insects. The Ringed Map Turtle is one of those with a narrower head. Behind the eye is a large yellow spot and two yellow horizontal stripes with another yellow stripe covering the lower jaw.
   As with many of the map turtle species, there is extreme sexual dimorphism in the Ringed Map Turtle. It is a small species with females only reaching 8" in length, but mature males are even smaller reaching only 4".

Care and Feeding:    Map turtles are omnivores. In captivity, the majority of their captive diet consists of floating aquatic turtle food, a variety of aquatic plants and greens, and some protein. Freeze-dried shrimp and krill are a great treat for map turtles.
   Interestingly, hatchlings and the young of several species of map turtles feed on more plant matter than adults. Physically, adults develop large, muscular jaws in response to a natural diet of hard-shelled snails and crayfish. They also eat a wide variety of aquatic insects. In fact, in some species the small males never leave this existence of feeding on aquatic insects in the shallows at the river's edge.
   Care must be taken that these, and any turtles, are not released into a wild habitat. The reasons are many. The introduction of non-native species can lead to the introduction of diseases and can lead to hybridization of introduced and native species. In addition, many turtles raised in captivity and released into wild situations are confused, unable to cope with extreme weather changes, and many surely fall prey quite quickly to predators they may encounter.

Environment:
   Though similar in appearance to sliders and painted turtles, map turtles have some unique and specific needs. Map turtles are generally found in clear, fast-flowing rivers and so require plenty of filtration and oxygenated water in their captive enclosures. A large flow-through filtration system will work well for map turtles. You can also add a "spray bar" to the filtration system to add some turbulence and oxygen to the water.
Indoors:
   Indoors, a basic setup in a large tub (48"w x 84"l x 20"deep) will be sufficient to keep and breed an adult trio of map turtles. Add an efficient filtration system, a shop light fixture with UVB-emitting bulbs overhead, and a warm basking spot. Map turtles spend a great deal of time exploring intricate underwater structures such as tree limbs, partially submerged stumps, and piles of rock. They climb around on these structures to search for a good basking spot, to find a bit of food, and to stay out of each other's way. Add bunches of submerged and floating plants. Within a few days these plants are usually picked apart, so move the leftovers outside to regrow and add a fresh batch of aquatic plants to the tub.
   Large female map turtles are often aggressive to the subordinate males and to any smaller turtles housed with them. Therefore, it is important to add plenty of decorations and an extra basking spot or two to their environment, and to avoid crowding.
Outdoors:
   Map turtles thrive in outdoor ponds. They are avid baskers so at least one large basking spot should be available. They will hibernate and care must be taken to formulate a plan for a moderately cool hibernation area. Most southern species will need to be brought inside as winter approaches (below 45{deg} to 50{deg} F). They should, however, be kept cool during the winter in an effort to inspire courtship and breeding behavior once they are returned to a warm outdoor enclosure in the spring.
   In outdoor enclosures, it is best to not crowd your map turtles. The addition of lots of aquatic plants, especially floating varieties (water lettuce, water hyacinth, and duckweed) to help keep the outdoor map turtle pond healthy and keeps the oxygen level high.

Handling:    Captive-hatched specimens, as always, are the best to keep as pets and most will become so docile that they can easily be fed by hand. These and all aquatic turtles should be considered wonderful display animals and not pets that are easily held.

Breeding:    Warm sunny days (outside) and increased warmth and water spray (indoors) provide for the onset of courtship and breeding in most map turtles. Most species lay well indoors when offered a laying area of damp sand and peat moss. With this type of environment, the females will search out the proper laying area rather than dropping eggs in the water. Hatching is straightforward. 75-80 days at 82{deg} F (28{deg} C) and 80-85% humidity should produce an average hatching success rates of 90% and higher.
   Map turtles are good layers in outdoor enclosures provided they have easy access to a proper laying area. Once this laying area has been discovered and "tested", the females will rarely lay elsewhere.
   Ringed Map Turtle females typically lay only 3 to 4 eggs per clutch. The shy hatchlings feed on a variety of insects and insect larvae and enjoy daily feedings of mosquito larvae and live blackworms.  In a 20-gallon long aquarium with 5-6" of clean, filtered water, driftwood, and live plants, they grow quickly.

Ailments / Health Problems:    Map turtles are often afflicted with shell problems in captivity. If not offered natural sunlight and indoor UVB, they will often develop a mild form of fungal infection. It is usually not complicated with ulceration, but appears as white or gray patches that will spread over most of the carapace if left untreated. Acriflavine, Betadine® scrubs, and drying out in direct sunlight have proven to be effective in preventing the spread of this fungus.

Availability:    The Ringed Map Turtle is one of the rarer species. They are being bred in captivity but in smaller numbers than some of the more common map turtles. Those that are produced are typically traded among breeders searching for genetic bloodlines for their programs. However it is only a matter of time before more species are commonly available from turtle breeders. A new keeper should try to find specimens that are captive-hatched and at least six to eight months old to ensure the turtle has been feeding well and is well on its way to a strong start.

    I was about to register when a storm struck "and we were off line". I am ancient heading on 60, eeeeek. but the animal world is a disease!
    Dear Michelle,
    I am looking for large aquatic turtles preferably, as re feed time things can be a bit dramatic. I have bred turtles, saved salamanders each year, mended peragrin falcons, deer + countless animals over the years. However you never stop learning!
    I also have searched for Rough Green Snakes for three years and never found anybody selling them, or (spotty frogs) as I call them, Bombina Orientalis. I do not know if you can help? I know 2 places in Fr. One Savannah going down hill, and the other only sells from the shop in Paris.....I am right down near Spain in the Pyrenees Atlantique, sorry no accents cannot find them on this arabic key board :)
    What happens re transport, Savannah used to transport very well, but no longer.
    Thank you for reading this; and I look foward to hearing from you.
    Fran
    I will now see if I can go back and finish regestering for this site. Take care.

Ringed map turtles are an endangered species - so I think it is not a PET!
