False Map Turtle

False Map turtles are found in along rivers from Texas to Florida and north to the Great Lakes, fascinate ecologists and evolutionary biologists. Over a short geologic time span, these turtles achieved exceptional biological diversification. Their diets are also exceptionally diverse, and a significant difference in size distinguishes males from females. Adult males are typically half or less the shell length of adult females, making map turtles the champions of sexual dimorphism among not only turtles but all four-legged vertebrates.
