Florida's panhandle is the most biologically rich area of the state. The
number of turtle species in the region is a good example of this diversity.
Over the last few million years, repeated sea level changes covered much
of the Florida peninsula with saltwater, altering freshwater ecosystems
and killing the organisms adapted to freshwater. Rivers and streams at
higher elevations in northwest Florida served as a refuge for freshwater
species, allowing these species to survive and diversify.
At 16 species, the Apalachicola River basin supports the highest number
of reptile and amphibian species in Florida, the second highest in the
United States, and the third highest in the world. The only two rivers
that are home to more turtle species are the Mobile River in Alabama,
which has 18, and the Ganges River in India, which has 19 species of turtles
living in its waters.

Barbor's Map Turtle
Graptemys barbouri
Barry Mansell photo
Discovered in 1941, this turtle lives only
in the Apalachicola drainage system, preferring areas of
the river with exposed limestone and strong currents. Highly
aquatic, over-land dispersal is unknown. The limited range
of this species makes it vulnerable to extinction.

Alligator Snapping Turtle
Macrochelys temminckii
Richard Franz photo
Found
throughout the southeast, this large turtle (up to 200 pounds)
has a huge head and long tail. Prefers deep rivers and canals.
Highly aquatic, does not bask, and rarely leaves the water
except to lay eggs. Over-harvesting for meat is the major
threat to this species.
