Black-knobbed Map Turtle
Graptemys nigrinoda
Black-knobbed Map Turtles inhabit slow rivers, oxbows, marshes, and other quiet waters of the Mobile Bay drainage in Alabama and Mississippi. Adults spend much of the day basking on logs, but slip quickly into the water when disturbed. They feed mainly on aquatic insects, mollusks, and other small aquatic invertebrates, using their strong jaws to crush or seize prey. The raised dark knobs along the center of the shell give this map turtle its distinctive common name.
