Alligator snapping turtles are the heaviest freshwater turtle in North America, declining from overharvest and habitat loss. Illegal collection for the pet trade and for meat continue to reduce wild populations in the southeastern US.
Alligator snapping turtles captured for the pet or food trade experience stress from handling, inappropriate transport conditions, and inability to meet their highly specialised ecological requirements in captivity. Longevity means that illegally collected individuals represent decades of lost reproductive potential. Juveniles and adults captured together represent different demographic impacts, with adult females being critical to slow-reproducing populations.
