Species – Macrochelys temminckii
The alligator snapping turtle is native to the southeastern United States, inhabiting river basins of the Mississippi, Missouri, and Ohio rivers. It prefers slow-moving freshwater habitats such as swamps, oxbow lakes, and muddy-bottomed rivers. Lifespan in the wild, these turtles can live 50–70 years, while in captivity they may reach up to 100 years. Adult males weigh between 45 and 80 kg, occasionally up to 100 kg. Females are smaller — around 20–30 kg. Shell length ranges from 40 to 80 cm, with a width up to 60 cm. They are characterized by massive heads and extremely powerful jaws.
The species is solitary and territorial. Breeding occurs in spring. Females lay 10–50 eggs in nests dug near water. Incubation lasts 100–140 days, and hatchlings head directly to the water after emerging. They are primarily nocturnal ambush predators, remaining motionless on the bottom with mouths open — their worm-like tongue tip lures prey into striking range. Carnivorous and opportunistic — feeds on fish, amphibians, crustaceans, small mammals, aquatic birds, and carrion. Occasionally consumes aquatic plants.
The genus Macrochelys originated around 15–20 million years ago during the Miocene. It descends from ancient freshwater predatory turtles native to North America.
The alligator snapping turtle is one of the largest and most ancient freshwater turtle species. Its distinctive prehistoric look has made it popular in documentaries and movies as a “living fossil.” Historically, it was overharvested for meat, leading to population decline.
According to the IUCN Red List, the species is classified as Vulnerable. Major threats include habitat destruction, pollution, and illegal capture. It is protected by law in most U.S. states.
5 Interesting facts:
- It is the largest freshwater turtle in North America.
- Its jaws can bite through a broom handle.
- The turtle uses a worm-like tongue lure to attract fish — a unique hunting adaptation.
- It has remained almost unchanged for millions of years, earning the title “living fossil.”
- Despite its fearsome appearance, it is generally non-aggressive and prefers to avoid confrontation underwater.
