About this species
The black-knobbed map turtle, formerly known as the black-knobbed sawback, is a small to medium-sized aquatic turtle with light gray skin. Some of the most distinguishing characteristics of the black-knobbed map turtle, and the Graptemys genus, are the protruding "spikes" on the turtle's carapace. This species inhabits mainly the fall lines of rivers in the Mobile Bay drainage, in Alabama and Mississippi.
