Everything You Need to Know About Alligator Snapping Turtles
Beneath the waters of the southern United States, the Alligator Snapping Turtle lurks. Known for its massive size, powerful bite, and prehistoric look, this turtle is one of the most fascinating creatures in North American waters!
Size and Weight
Alligator Snapping Turtles (Macrochelys temminckii) are among the largest freshwater turtles in the world. These beasts can grow to an impressive 26–39 inches (66–99 cm) in length and weigh in at over 200 pounds (90 kg) on average! Supposedly, the largest recorded Alligator Snapping Turtle weighed an incredible 249 pounds (113.4 kg) and measured nearly 30 inches (76 cm) long!
Diet
Alligator Snapping Turtles are carnivorous ambush predators, relying on their powerful jaws to catch prey. Their diet includes:
- Fish 🐟
- Snakes 🐍
- Smaller Turtles 🐢
- Birds 🐦
- Insects 🕷️
- Crustaceans (such as crayfish) 🦞
They use a unique hunting technique where they open their mouths wide, hiding their sharp teeth, and wiggle a pink, worm-like appendage on their tongue to attract fish. Once the prey gets close, the turtle snaps its jaws shut with lightning speed!
Fun Fact: Alligator Snapping Turtles can wait submerged and motionless for so long that algae begins to grow on their shells. They can go up to 50 minutes without needing a breath of air!
Lifespan and Reproduction
In the wild, Alligator Snapping Turtles has a lifespan of up to 50 years, though some in captivity have been known to live even longer with the right care. These turtles grow slowly, reaching maturity at around 11–13 years of age.
Alligator Snapping Turtles lay their eggs in sandy nests. A female may lay anywhere from 10 to 60 eggs in a single clutch, and the eggs will incubate for around 100–140 days before hatching. The hatchlings are independent from the start and must find food and shelter immediately.
Habitat
Alligator Snapping Turtles are native to the slow-moving rivers, swamps, and lakes of the southeastern United States, including:
- Alabama
- Arkansas
- Florida
- Georgia
- Illinois
- Kentucky
- Louisiana
- Missouri
- Mississippi
- Oklahoma
- Tennessee
- Texas
They are often found in small streams to large rivers, oxbows, springs, swamps, bayous, lakes, and canals. Their strong jaws and camouflaged appearance make them perfect ambush predators in these habitats!
