Common snapping turtle

The snapping turtle lives in ponds and streams.

It has a bumpy, hard shell. The shell can be tan or black. This turtle has a very long neck. It can stretch its neck to reach the surface for air.

The turtle eats plants and small fish. It also eats frogs and birds. Some turtles can live for over 100 years! They are very big and strong animals.

The common snapping turtle is a large turtle found in fresh water.

They live in places like Canada and Florida. These turtles have a bumpy shell. The shell color can be tan, brown, or black.

They have very long necks. This lets them stretch to the surface for air. Their nostrils are on the tip of their snout. This helps them breathe like a snorkel.

Snapping turtles eat many things. They are omnivores, which means they eat both plants and meat. They hunt fish, frogs, and small birds. They also eat dead animals.

These turtles are very tough. They can live for over 100 years. In the winter, they stay under the ice. They can breathe through the skin in their mouth and throat. This is called extrapulmonary respiration. This way helps them get oxygen without using their lungs. They can even stay under the ice for six months!

The common snapping turtle is a large turtle that lives in fresh water.

These animals can be found in many places. Their range goes from southeastern Canada to Florida. They also live near the Rocky Mountains and Nova Scotia. This turtle is a habitat generalist. This means it can live in most permanent bodies of water. It likes shallow ponds, streams, or even areas where salt and fresh water mix.

This turtle has a very interesting way of staying alive. It is an omnivore, so it eats both plants and meat. It hunts fish, frogs, snakes, and even small mammals. It also acts as a scavenger by eating dead animals. To breathe underwater, it uses a special method called extrapulmonary respiration. This means it can take in oxygen through the membranes in its mouth and throat. This is very helpful when ice covers its water for many months. It can even stay under the ice for six months at a time.

Scientists have studied these turtles for a long time. We know they have been in the Middle Rio Grande area since at least the 1600s. In Ontario, Canada, researchers used mark-recapture data to learn about their lives. This data showed that some turtles can live for over 100 years.

They grow throughout their entire lives. While most adults weigh around 20 pounds, some can be much heavier. One wild specimen was even reported to weigh 75 pounds.

There are many specific facts about how they grow and move. A female turtle can lay between 25 and 80 eggs each year. These eggs have a soft, leathery shell. The temperature of the nest decides if the babies will be male or female. Higher temperatures make the eggs hatch faster. In the north, turtles may take 15 to 20 years to mature. In the south, they might reach maturity in only 12 years.

Watching a snapping turtle can be a surprising experience. They have a very flexible neck that can stretch far. This is why their scientific name, *serpentina*, means "snake-like."

They can also make clicking or creaking sounds when they are inside their nests. If they feel stressed, they might release a smelly musk from behind their legs. While they can be fierce, they often prefer to hide in the mud when they see people.

The common snapping turtle (*Chelydra serpentina*) is a large species of freshwater turtle. It belongs to the family Chelydridae. This family is now restricted to the Americas. The common snapping turtle is the most widespread member of this group.

It is a vital part of its ecosystem. These turtles act as important aquatic scavengers. They also serve as active hunters in many habitats. Their presence helps manage populations of various aquatic species.

These turtles have a very unique physical build. They possess a rugged and muscular body. Their carapace, or upper shell, is heavily ridged. The color of the shell varies from tan to black.

Adults can reach a straight-line carapace length of nearly 18 inches. Most adults weigh approximately 20 pounds. However, some individuals are much larger. One reported wild specimen weighed 75 pounds. Males are generally larger than females. Most males weigh more than 20 pounds. These turtles continue to grow throughout their entire lives.

Common snapping turtles are highly adaptable habitat generalists. They can occupy most permanent bodies of water. This includes shallow ponds, streams, and even brackish estuaries.

In shallow water, they often hide beneath the muddy bottom. They may stretch their long necks to the surface to breathe. Their nostrils are located at the very tip of the snout. This positioning allows them to function like snorkels. They also have a strong sense of smell. This is due to well-developed olfactory organs and nerves.

As omnivores, these turtles have a varied diet. They hunt fish, frogs, snakes, and small mammals. They also eat many invertebrates and unwary birds. Because they are scavengers, they also consume carrion. They eat a surprisingly large amount of aquatic vegetation too. Young turtles have a lower bite force than adults. Because of this, they must travel more to find food. This active foraging helps them make up for their limited diet.

Survival strategies for these turtles vary by location. In northern populations, they mature later. They may take 15 to 20 years to reach sexual maturity. These northern turtles also grow to a larger size. In southern populations, they mature in about 12 years.

The species is known for its long life. Data from Algonquin Park in Ontario suggest they can live over 100 years. Their reproduction involves repeated events, known as iteroparity. However, they often have low reproductive success per event.

Reproduction is a complex process for the common snapping turtle. Females travel over land to find sandy soil for nests. They can sense the Earth's magnetic field to help with movement.

A female typically lays 25 to 80 leathery eggs. The incubation time depends on the temperature. At 30 °C, eggs hatch in about 63 days. At 20 °C, it takes about 140 days. Temperature also determines the sex of the hatchlings. High and low temperatures produce females. Intermediate temperatures produce males.

These turtles have remarkable ways of handling cold weather. In the north, they may hibernate under ice for six months. They use a process called extrapulmonary respiration to survive. This allows them to take in oxygen through mouth and throat membranes.

If oxygen is still low, they use anaerobic pathways. This means they burn sugars and fats without oxygen. This process creates an acidic oxygen debt by spring. While they are hardy, they face many predators. Eggs are eaten by raccoons, foxes, and crows. Hatchlings face threats from birds, fish, and snakes. Large adults have very few natural threats left.
