The Mississippi map turtle (Graptemys pseudogeographica kohni) is a subspecies of land and water turtle belonging to the family Emydidae. G. p. kohni is endemic to the central United States. Map turtles get their common name from the lines and markings on their carapace which resemble the contour lines of a map. They occur in the Mississippi Valley from Illinois and Nebraska, down into the Gulf States from Mississippi to Texas, usually in rivers, lakes and large streams (not typically in isolated farm ponds or small creeks). They tend to prefer habitat with abundant vegetation.

Etymology

The Mississippi map turtle derives its common name not from the state of Mississippi, but rather from the Mississippi River.

The specific name, kohni, is in honor of amateur naturalist Joseph Gustave Kohn (1837-1906) of New Orleans, Louisiana, who collected the type specimen.[3][4]

Geographic range

It is found along the Mississippi River and its tributaries, from Illinois and Missouri southward.[5]

Description

Females are considerably larger than males, the adult male being 3.5 to 5 inches (about 9 to 13 cm) in carapace length, and the adult female from 6 to 10 inches (about 15 to 25 cm) in carapace length. Males have a leaner look, more like juveniles, but females have a larger, bulkier build.

Captivity

It is a popular pet for aquarists and is very enjoyable to watch.
