Snapping turtles are freshwater turtles in the family Chelydridae, known for their powerful jaws and defensive biting behaviour. In North America, the term usually refers to the common snapping turtle (Chelydra serpentina) and the alligator snapping turtle (Macrochelys temminckii). They live mainly in freshwater habitats, though they can also use brackish water.
Taxonomy and species
Snapping turtles belong to the family Chelydridae. Modern sources identify two living species: the common snapping turtle (Chelydra serpentina) and the alligator snapping turtle (Macrochelys temminckii).
Description and behaviour
Snapping turtles are large freshwater turtles with strong jaws, long necks, and a defensive bite. They are generally not aggressive unless threatened or handled.
Habitat and range
They live mostly in freshwater habitats such as ponds, lakes, rivers, creeks, and marshes, and can also occur in brackish water. Their North American range extends through much of eastern and central North America, including southern Canada.
Diet and ecology
Snapping turtles are omnivores and opportunistic feeders. They play an important ecological role as predators and scavengers in aquatic ecosystems.
Human interactions
Snapping turtles are sometimes hunted or used as food in some regions. They can accumulate pollutants in their tissues, which is a concern in areas with contaminated waterways.
Key facts
- Snapping turtles are named for their snapping or biting defensive behaviour.
- The family Chelydridae has two living species: the common snapping turtle and the alligator snapping turtle.
- They are large, highly aquatic turtles that usually live in shallow ponds, streams, rivers, marshes, and similar waterways.
- They are opportunistic omnivores that eat plants, carrion, fish, amphibians, invertebrates, and small vertebrates.
- They are long-lived reptiles, with wild lifespans commonly cited at around 30 years or more.
Snapping turtles are part of Canada’s native reptile fauna, with ranges extending into southern provinces. Canadian readers may encounter them in wetlands, lakes, rivers, and other freshwater habitats, especially in eastern and central regions.
