The common snapping turtle is a species of large freshwater turtle native to the Americas. It is known for its aggressive behaviour and powerful jaws when on land, but in water, snapping turtles are typically shy and gentle creatures. They are also known to play dead when they feel threatened. When approached on land, a snapping turtle will often elevate its hindquarters, gape its jaws, and lunge at the source of danger. However, when confronted by a larger animal in the water, they usually retreat or withdraw.

What You'll Learn
Snapping turtles are not aggressive and will not attack/bite unless provoked
Snapping turtles are not aggressive creatures and will only attack or bite when they feel threatened or provoked. In the water, snapping turtles are incredibly docile and will go to great lengths to avoid humans. They are also very abundant and occupy the vast majority of water bodies, including small swimming ponds. While it is technically possible, a bite from a snapping turtle in the water is incredibly rare.
On land, snapping turtles are more likely to bite, especially during the nesting season. They will defend themselves when someone or something tries to bother them and are capable of delivering very powerful bites. However, even on land, they will not attack or chase you. They will only defend themselves when threatened.
Snapping turtles are the only turtles that do not have a sufficiently large plastron (an undercarriage), so they cannot hide or tuck in like other turtles. Therefore, the only way they can protect themselves on land is to snap. However, they are actually afraid of humans on land and will only snap in defence when they feel threatened. They would prefer to retreat or for you to get out of their way.
Snapping turtles are slow on land and cannot outrun predators. Unlike most other turtles, their bodies are too large to fit fully within their protective shells. Instead, they rely on their large size and scary demeanour to hold their ground and defend their position when approached.
Overall, snapping turtles are not aggressive and will only bite when provoked. They are more likely to bite on land, especially during the nesting season, but even then, they will only defend themselves and are unlikely to chase or attack.

They are top predators in many food chains
The common snapping turtle is a top predator in many food chains. They are ambush predators, lying in wait for prey to come within reach before snapping them up with their powerful jaws. They are also important aquatic scavengers, feeding on dead organisms.
The common snapping turtle is an omnivore, consuming both plant and animal matter. They are highly opportunistic, scavenging in the mud along the bottom of water bodies and using their well-developed olfactory organs to detect food sources. They will eat anything they can swallow, including invertebrates, fish, amphibians, reptiles, birds, and small mammals.
The common snapping turtle's diet is not limited to live prey. They are also important for cleaning the water, removing dead and decaying bodies of fish, frogs, and other creatures from lakes and other bodies of water. Without turtles, bacteria levels in the water would increase.
The common snapping turtle is a key part of the ecosystem, controlling the populations of various mammals, amphibians, mollusks, reptiles, and insects they prey on. They also spread seeds that grow into plants that support fish nurseries and wetland ecosystems.

They are important for cleaning the water and supporting biodiversity
The common snapping turtle is an important contributor to the health of lakes and other bodies of water. They are the best at cleaning the water, removing dead and decaying bodies of fish, frogs, and other creatures. They are like the turkey vultures of lakes. Without turtles in your lake, bacteria levels will increase.
The common snapping turtle is a top predator in many food chains and is an important component of aquatic ecosystems. They are also important aquatic scavengers and help with "natural recycling". They are agents of biodiversity, spreading seeds that grow into plants that support fish nurseries and wetland ecosystems. More than 70% of fish and wildlife in Ontario rely on these areas to survive.
The common snapping turtle is an omnivore, feeding on both plant matter and animals. They are active hunters, using ambush tactics to prey on anything they can swallow, including invertebrates, fish, amphibians, reptiles, birds, and small mammals. They are also scavengers, feeding on carrion and a large amount of aquatic vegetation.
The common snapping turtle is not aggressive and will not attack or bite people or pets unless they are purposefully provoked. They are shy, curious, and gentle creatures in the water, where they are top predators and can swim very well.

They are sacred creatures, as old as the dinosaurs
The snapping turtle is a sacred creature, as old as the dinosaurs. They are said to have been present at the creation of the world and witnessed all of Creation. They are a symbol of Truth, and it is believed that the earth was created on a turtle's back, referred to as Turtle Island.
The snapping turtle is a large freshwater turtle species, known for its combative disposition when out of the water. Its powerful beak-like jaws and highly mobile head and neck give it a snake-like appearance. In water, however, they are more likely to flee and hide underwater in the sediment.
These turtles are top predators in their ecosystem and play an important role in maintaining biodiversity. They are excellent at cleaning the water, feeding on dead and decaying matter, and removing the bodies of fishes, frogs, and other creatures from lakes and waterways. They are essential for human health, as their presence helps keep bacteria levels in check.
Snapping turtles have a long lifespan, with some individuals living over 100 years, and evidence suggesting they can live for more than 400 years. They are slow to reproduce, with females reaching maturity between 12 and 20 years of age. This, coupled with high mortality rates among embryos and hatchlings, means that adult turtles are crucial for sustaining their populations.
Despite their fierce appearance and disposition on land, snapping turtles are generally docile and non-confrontational when in the water. They are curious creatures and will often survey unfamiliar objects or beings, such as humans, without provoking a confrontation. In fact, they will usually slip quietly away from any disturbance or seek shelter nearby.
The snapping turtle is a protected species in some places, and harming or moving them can result in large fines. They are highly territorial and rely on mental maps of their territories to navigate and survive. Moving them from their natural habitats can lead to their death, as they are unable to create new mental maps as adults.
Overall, the snapping turtle is a fascinating and ancient creature, playing a vital role in maintaining the health and biodiversity of our planet's waterways.

They are remarkably cold-tolerant
The common snapping turtle is remarkably cold-tolerant. Radiotelemetry studies have shown that some individuals do not hibernate but remain active under the ice during winter. In the northern part of their range, snapping turtles do not breathe for more than six months because ice covers their hibernating site.
To survive without oxygen, snapping turtles can push their heads out of the mud and allow gas exchange to take place through the membranes of their mouths and throats. This process is known as extrapulmonary respiration. If they cannot get enough oxygen through extrapulmonary respiration, they start to utilise anaerobic pathways, burning sugars and fats without the use of oxygen.
The metabolic by-products from this process are acidic and create undesirable side effects by spring, known as oxygen debt. In cooler climates, baby snapping turtles will overwinter in the nest.
The common snapping turtle is native to southeastern Canada and the northern United States, where it is well-adapted to cold temperatures. Its natural range extends southwest to the edge of the Rocky Mountains and as far east as Nova Scotia and Florida.
