Alabama map turtle

The Alabama map turtle is a species of emydid turtle native to the southern United States. Differentiation from other turtle species includes a black stripe running down the center of its back with knobs extruding from it, but these projections wear down with age. T.H. Bean and L. Kumlen first collected the Alabama map turtle in July 1876 from a lake near Montgomery, Alabama. Type locality for this species is Montgomery County, Alabama. German zoologist Georg Baur described and named the Alabama map turtle in 1893. The genus Graptemys includes nine species of mostly aquatic turtles.
