The Alligator snapping turtle is one of the heaviest freshwater turtles in the world.
This turtle is given its common name because of its immensely powerful jaws and distinct ridges on its shell that are similar in appearance to the rough, ridged skin of an alligator.
Alligator snapping turtles have a large, heavy head, and a long, thick shell with three dorsal ridges of large scales (osteoderms), giving them a primitive appearance reminiscent of some of the plated dinosaurs.
The turtles are a solid gray, brown, black, or olive-green in color, and often covered with algae.
.
Their eyes are also surrounded by a star-shaped arrangement of fleshy, filamentous “eyelashes“.
– Distribution –Alligator snapping turtles are found primarily in southeastern United States waters.
They are found from the FloridaPanhandle west to East Texas, north to southeastern Kansas, Missouri, southeastern Iowa, western Illinois, southern Indiana, western Kentucky, and western Tennessee.
They are found on the Missouri River at least as far north as the Gavins Point Dam, the southernmost dam on the Missouri River at Yankton, South Dakota, and are featured in the Gavins Point Dam Aquarium. Alligator snapping turtles live rivers, lakes, and canals.
– Habits and Lifestyle –Alligator snapping turtles spend most of their lives in water and only nesting females venture onto open land. They are solitary creatures.
These turtles most often hunt at night, however, they may also feed during the day.

These turtles are able to stay submerged for 40-50 minutes before surfacing for air and will even hibernate during winter at the bottom of ponds and lakes.
When underwater Alligator snapping turtles may stay so motionless that algae can cover their backs and make turtles almost invisible to fish.
.
They also eat snakes, crayfish, worms, water birds, aquatic plants, other turtles and sometimes even Alligators.
.
Their breeding season takes place yearly, in early spring in the southern part of their total range, and later spring in the north.
The female builds a nest and lays a clutch of 10-50 eggs about two months later. The gender of the young depends on the temperature at which the eggs are incubated.
Nests are typically excavated at least 50 yards from the water’s edge to prevent them from being flooded and drowned.
Incubation takes from 100 to 140 days, and hatchlings emerge in the early fall.
They are independent at birth and don’t need parental care. Young Alligator snapping turtles reach reproductive maturity at around 12 years of age.
.
– Population number –The IUCN Red List and other sources don’t provide the number of the Alligator snapping turtle total population size. Currently, this species is classified as Vulnerable (VU) on the IUCN Red List.
