Commercial fisherman in Louisiana capture alligator snapping turtles with a baited hook mostly by trot line fishing. Some skilled fisherman however probe the water's bottom with a long pole and then use a metal hook to grab it. Overkilled in Louisiana; population seriously depleted.
Lift by grasping anterior and posterior ends of carapace. Grasping and holding by tail can injure turtle's vertebrae column.
Lays 17-40 round eggs in nest/hole in ground near water source. Female digs hole 20 inches deep and 1 foot around with hind feet; covers eggs by filling in hole. Eggs hatch 10 weeks later in late summer. Turtles find their way to water instinctively.
Vulnerable; protected in some states; suffers from over hunting.
