common snapping turtle

The common snapping turtle (Chelydra serpentina) is a freshwater turtle species found across North America, from Canada to South America. These turtles are known for their large size, aggressive biting, and distinctive physical features, including a rough upper shell, a small lower shell, a long tail, and a hooked jaw.1

Common snapping turtles are omnivorous, with a preference for animal prey such as fish, frogs, and snakes. While generally not aggressive in water, they can become defensive on land. Females lay 20 to 40 eggs, and the young hatch with shells about 2.5–4 cm long. The common snapping turtle is often found in shallow water, sometimes buried in mud.12

The alligator snapping turtle (Macrochelys temminckii) is the largest freshwater turtle in North America, distinguished by three prominent ridges on its shell and a wormlike lure in its mouth used to attract prey. It primarily inhabits deeper waters like lakes, swamps, and rivers.13
