Snapping turtles are a family of freshwater turtles known for their powerful jaws and aggressive defense mechanisms. They are some of the most widespread and ancient turtles in North America, with a lineage dating back millions of years. Unlike many other turtles, they are more likely to be found lurking at the bottom of lakes and rivers rather than basking on logs. Below are some fascinating facts about these unique reptiles.
1. There are two species of snapping turtles
The two recognized species are the common snapping turtle (Chelydra serpentina) and the alligator snapping turtle (Macrochelys temminckii).
The common snapping turtle is widely distributed across North America, ranging from Canada down to Florida and as far west as the Rocky Mountains. It has a dark, rough shell that can reach up to 18 inches in length, with an average weight between 10 and 35 pounds. This species is highly adaptable, living in lakes, ponds, rivers, and marshes.
The alligator snapping turtle is significantly larger, with some individuals exceeding 200 pounds and measuring over 30 inches long. This larger species of snapping turtle is primarily found in the southeastern United States, inhabiting deep rivers, bayous, and swamps. Unlike the common snapper, it has a heavily ridged shell resembling an alligator’s back and a unique worm-like appendage in its mouth that it uses to lure prey.
2. Snapping Turtles have an incredibly powerful bite
Snapping turtles are known for their strong jaws, capable of delivering a powerful bite force of up to 1,000 psi. While they don’t typically bite unless provoked, their sharp beaks can easily snap through bones, fish, and even other turtles. Because they cannot fully retract into their shells for protection like other turtles, they rely on their aggressive defense mechanism to deter predators.
3. They rarely leave the water
Unlike many turtles that spend time basking in the sun on logs or rocks, snapping turtles prefer to stay submerged in water for most of their lives. They are excellent swimmers and often bury themselves in mud or vegetation at the bottom of lakes and ponds, waiting for prey to pass by. The only time they venture onto land is when females lay eggs, typically in sandy or soft soil near water.
4. Snapping turtles can live for decades
Snapping turtles have long lifespans, often living between 30 and 40 years in the wild. Some individuals have been known to survive over 50 years, especially in protected environments. Their slow metabolism and ability to adapt to different habitats contribute to their impressive longevity.
5. Their eggs are a favorite snack for predators
While adult snapping turtles have few natural predators due to their size and strength, their eggs are highly vulnerable. Animals such as raccoons, foxes, skunks, and crows frequently raid their nests, sometimes destroying entire clutches. A female snapping turtle may lay 20 to 50 eggs at a time, but only a small percentage of hatchlings survive to adulthood.
6. Snapping turtles can breathe underwater through their skin
Snapping turtles have an amazing ability to absorb oxygen through their skin and cloaca (a rear body opening) while submerged. This allows them to stay underwater for extended periods, even in icy conditions. In winter, they often burrow into mud and rely on this method of respiration to survive until warmer temperatures return.
7. They’ve been around for over 90 million years
Snapping turtles are one of the oldest surviving turtle species, dating back to the age of the dinosaurs. Their primitive design has remained largely unchanged, allowing them to thrive for millions of years. Their rugged shells, strong jaws, and adaptable nature have contributed to their longevity as a species.
8. They use their sense of smell to locate food
Unlike many reptiles that rely on vision, snapping turtles have an excellent sense of smell, which helps them find food even in murky water. They use their powerful nostrils to detect fish, amphibians, carrion, and even plant matter. This heightened ability allows them to be highly effective scavengers and hunters.
9. Snapping turtles are more aggressive on land
Snapping turtles tend to be far more defensive and aggressive when on land than in water. This is because they feel vulnerable outside their aquatic environment, where they cannot rely on quick escapes. If approached, they will hiss, lunge, and bite as a defensive strategy. In the water, however, they are more likely to swim away rather than confront a threat.
10. Their shells do not regenerate if damaged
Unlike some reptiles that can regrow body parts, snapping turtles cannot heal major injuries to their shells. While small cracks or minor damage may repair over time, a severe injury—such as being hit by a car—can be fatal. This makes road crossings particularly dangerous for them, especially during nesting season when females travel to lay eggs.
11. Some snapping turtles have been found in brackish water
Although they prefer freshwater environments like lakes, ponds, and slow-moving rivers, snapping turtles have occasionally been found in brackish water. While they are not true saltwater species, their adaptability allows them to tolerate varying salinity levels for short periods.
12. Hatchlings instinctively head for water
As soon as they emerge from their eggs, baby snapping turtles make a direct path toward the nearest body of water. Unlike some other turtle species, they receive no parental care, relying entirely on instinct to survive. Their small size and soft shells make them easy targets for predators during this journey.
13. The species plays a key role in balancing ecosystems
Snapping turtles help regulate fish and amphibian populations by preying on weaker individuals. As opportunistic feeders, they also scavenge carrion, keeping waterways cleaner by consuming dead or decaying animals. Without them, some ecosystems would experience population imbalances among certain aquatic species.
14. A snapping turtle’s tail looks like something from the prehistoric era
One of the most distinctive features of a snapping turtle is its long, ridged tail, which resembles those seen on prehistoric reptiles. The tail often grows nearly as long as the shell itself, giving these turtles an even more ancient, dinosaur-like appearance.
15. Road crossings are a major danger for snapping turtles
During nesting season, females often travel far from water to find suitable places to lay eggs. This sometimes leads them onto roadways, where they are vulnerable to being hit by cars. If helping a snapping turtle cross a road, always move it in the direction it was heading to avoid confusion.
16. A snapping turtle’s bite can cause serious injury
While they don’t actively seek to harm humans, snapping turtles can deliver a painful bite if handled improperly. Their powerful jaws can slice through flesh and even break small bones. Unlike some animals that deliver warning bites, a snapping turtle often holds on tightly once it latches down.
17. Many people fear snapping turtles, but they are not aggressive
Despite their reputation, snapping turtles are not out to attack people. They prefer to avoid confrontation and will usually swim away when approached in water. On land, where they feel more vulnerable, they may hiss and lunge if threatened, leading to the misconception that they are highly aggressive.
18. Keeping a snapping turtle as a pet is a bad idea
While some states may allow people to own snapping turtles, they do not make good pets. They grow large, require specialized care, they stink, and can be difficult to handle safely. Their strong bite and long lifespan, often exceeding 40 years, make them an impractical choice for most pet owners.
19. Snapping turtles have been found in unexpected places
Occasionally, these turtles turn up in unusual locations, far from their natural habitat. Some have been found wandering city streets, in backyard pools, and even inside storm drains. These unexpected appearances are usually the result of them following waterways or being displaced by flooding.
20. A giant snapping turtle once made headlines
In 2023, a massive snapping turtle nicknamed “Chonkosaurus” went viral after being spotted in the Chicago River. The turtle’s enormous size amazed viewers and highlighted the species’ resilience in urban environments. The story was covered by major news outlets, and Chonkosaurus quickly became an internet sensation.
21. Snapping turtles are always on the move in search of new water
These turtles are surprisingly mobile on land and will travel great distances in search of new water sources like ponds or slow-moving bodies of water. Droughts, overcrowding, or changes in habitat can force them to relocate. It’s not uncommon to see a snapping turtle crossing roads or fields as it moves between wetlands.
22. Snapping turtles are not social creatures
Unlike some turtles that gather in groups, snapping turtles are solitary animals. They do not form bonds or live in communal areas. Outside of mating season, they prefer to avoid others of their kind and will sometimes show aggression toward intruding turtles in their territory.
23. The largest alligator snapping turtles can weigh over 200 pounds
Alligator snapping turtles are the true giants of the snapping turtle world. Some of the biggest individuals have been recorded at over 200 pounds, with shell lengths exceeding 30 inches. Their dinosaur-like appearance and immense size make them one of the most fascinating freshwater turtles.
24. They have a unique mating process
Mating occurs in spring and early summer when males actively seek out females. A male will use his strong claws to grasp the female’s shell while mating occurs underwater. Unlike some reptiles, snapping turtles do not form long-term bonds, and after mating, the female is solely responsible for finding a nesting site and laying eggs.
25. They’re virtually silent animals, but they communicate in other ways
While many turtles are silent, snapping turtles can produce hissing sounds when they feel threatened. In water, they rely more on body language and movement rather than vocal communication. Mating behaviors, aggression, and territorial disputes are all expressed through posturing and physical contact rather than noise.
26. Snapping turtles eat a wide variety of food
These turtles are opportunistic feeders, meaning they will eat almost anything they can catch. Their diet includes fish, frogs, insects, crayfish, small mammals, and even aquatic plants. They also scavenge on dead animals, helping to clean up their environment by preventing decay from spreading disease in the water.
27. They can survive in frozen water by slowing their metabolism
During winter, snapping turtles enter a state of brumation, a form of hibernation where their metabolism slows drastically. They settle at the bottom of frozen ponds and absorb oxygen through specialized areas of their skin. This allows them to survive for months without surfacing for air, even in freezing conditions.
28. Some states have laws protecting snapping turtles
Due to habitat destruction and overharvesting, some areas have placed restrictions on catching or keeping snapping turtles. Certain states regulate hunting seasons, size limits, or even ban collecting wild turtles entirely. While they are not currently endangered, conservation efforts help ensure stable populations for the future.
