Identification
Very similar to the False
Map Turtle (Graptemys pseudogeographica pseudogeographica), there
is some debate between their relationship, and some sources refer to this animal
as Graptemys pseudogeographica kohnii. Regardless of the classification, the
Mississippi Map Turtle can best be identified by the crescent shaped light spot
behind the eye that prevents the neck stripes from reaching the eye. The skin
of the turtle is olive to brown and is marked with many narrow yellow stripes
along the legs, tail, chin and neck. The eye of the Mississippi Map Turtle is
white. The carapace is brown and the plastron is more patterned than that of
the False Map Turtle.
Distribution and Status
The natural range of the False Map Turtle extends from north central Illinois
to Louisiana, west through central Texas and eastern Kansas. In the Midwest,
this species is found in Indiana, Illinois, and Missouri. (US

Ecology
These turtles are good swimmers and prefer waters such as rivers and large creeks
with moderate current. The presence of aquatic vegetation, as well as snags
or floating logs, is also important to this species. Mississippi Map Turtles
are also comfortable in deep and swift water. In addition, these turtles can
be found in oxbow lakes and sloughs, but are usually absent from lakes, ponds,
or small streams.
Threats and Management Issues
The Mississippi Map Turtle, like many other “sawback” turtles, has
been exploited in the pet trade industry.
