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.
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]
Graptemys pseudogeographica kohni is found along the Mississippi River and its tributaries, from Illinois and Missouri southward.
Their grey shells are covered in yellow lines resembling contour lines.
The Mississippi map turtle is a popular pet for aquarists and is very enjoyable to watch.[ citation needed ]

Graptemys is a genus of freshwater turtles containing 14 species, commonly known as map turtles. Graptemys are small to medium-sized turtles that are sexually dimorphic, with females attaining as much as twice the length and ten times the mass as males in some species. Depending on the species, adult males range from 7–16 cm (2.75–6.25 in), adult females 10–29.5 cm (4–11.62 in), and hatchlings 2.5–3.8 cm (1–1.5 in), although some sources indicate female Barbour's map turtles grow to 33 cm (13 in) in length. Most species have a distinctive dark pigmented keel that is often notched or serrated running down the center of the carapace and serrated scutes on the rear margin. The head, neck, and limbs exhibit bold patterns of yellow lines and spots against darker green, olive, or black base colors. The patterns on the head can be important characters in identifying the various species. The common name "map turtle" is derived from the intricate patterns on their shells that are suggestive of topographical maps, although the patterns are more apparent in some species than others, and often become obscure in older specimens. Some species are occasionally called "sawbacks", in reference to the serrated keels on their shell.
