Two species live in the United States, the common snapping turtle and the alligator snapping turtle. They live in freshwater habitats and feed on small animals.
Alligator snapping turtle populations are declining and are considered an endangered species due to habitat loss, climate change, and poaching.
What are snapping turtles like?
Snapping turtles have distinctive features that make them easily identifiable.
There are two species of snapping turtles in the US, the common snapping turtle and the alligator snapping turtle. Both have prominent bumps on their shells, their skin is rough and bumpy, and the tops of their mouths curve into a sharp beak (1).
The alligator snapping turtle is larger with a triangular head and three prominent ridges along the carapace.
Common snapping turtles have a softer shell as they age, an oval head, and are more likely to be seen on the streets.
Despite their fearsome-looking facial features, snapping turtles are unlikely to harm humans unless they feel threatened.
Where do snapping turtles live?
Common snapping turtles have a fairly wide range, found throughout eastern North America everywhere east of the Mississippi River, including several Great Plains states.
The alligator snapping turtle is found only in 14 states in the southern US, primarily in waters that connect to the Mississippi River and empty into the Gulf of Mexico (1). Once abundant in rivers flowing into the Gulf, its range has been significantly reduced in Indiana, Illinois, Kansas, Kentucky, Missouri, Tennessee, and Oklahoma (7).
Both species live in fresh and brackish water, often with soft bottoms and lush vegetation (2). Submerged structures and vegetation not only hide them from predators, but also help them resurface to breathe and often contain higher densities of their prey (3).
What do snapping turtles eat?
Snapping turtles are omnivorous, eating both plants and animals. Prey species include fish, frogs, reptiles, birds, and mammals, as well as many invertebrates (4).
Alligator snappers tend to eat less vegetation than their common relatives and have been known to eat small alligators (4).

How is the common snapping turtle different from the alligator snapping turtle?
The common snapping turtle and the alligator snapping turtle are similar in many ways, but there are some distinctive features that set them apart.
The alligator snapper appears more "prehistoric" than the common snapper, with more pronounced ridges along its carapace, a more beak-like mouth, and a squarer head.
The alligator snapper is larger, usually between 20 and 175 pounds, but has been recorded to weigh up to 249 pounds (1). By comparison, snapper average 10 to 35 pounds, with the heaviest measuring 75 pounds (1).
worm shaped
The alligator snapping turtle also has a very unique trait. In its mouth it has a pink worm-like (worm-shaped) appendage that it uses as bait to attract prey (5). It sits at the bottom of a lake or river with its mouth open and fish are attracted to the bait and can swim right into the turtle's mouth!
It is the only turtle species in the world that uses this prey capture technique (5). They are less mobile than snapper and as such this lure technique is an important method of feeding.
They are in danger of extinction?
Alligator snapping turtles are classified as "vulnerable" by the IUCN and are not federally protected. This means that they are critically endangered in the wild (6). Some predict that they could be extinct within 30 years (7).
However, due to declining numbers, they are protected in many states, including Florida.Kentucky,and Georgia.
WhatUSFWShas proposed that the alligator snapping turtle be listed as threatened and deserve federal protection. An endangered animal is an animal that is likely to be in danger of extinction in the foreseeable future if it is not provided with protection.
human influence
Humans are primarily responsible for the disappearance of this important species. They were captured for the exotic pet trade, hunted for their meat and shellfish, and lost much of their habitat (6).
Habitat loss is causing snapping turtles to travel greater distances to find food and mates. This puts them in great conflict with roads and cars.
Like many species of turtles, they have been killed and injured as a result of suffocation and entanglement in fishing gear (7) andclimate changeit also plays a role in its decline. Turtles are reptiles, which means they are cold-blooded and therefore more vulnerable to changes in ambient temperatures.

In addition to their vulnerability, tortoises take a long time to reach maturity (around 20 years) and have low fertility and pup survival rates (7). Also, due to their long lifespan (50-100 years), they can accumulate toxins and pollutants from their environment, causing health and reproductive problems.
Snapper is not threatened, not yet!
As the name suggests, snapping turtles are not endangered in the US and their population is considered stable. They produce larger clutches than alligator snapper (8) and are found over a larger geographic area. In Canada, however, they are declining considerably.
This is mainly due to habitat loss. Therefore, it is important to protect and conserve such habitats in the US while the snapper population remains stable.
Are there snapping turtles in Wisconsin?
In fact, there are snapping turtles in Wisconsin. They are the common snappers and inhabit the freshwater and swampy lakes found there. They are one of 11 species of turtles found in Wisconsin, but they are the largest and heaviest.

Do snapping turtles have predators?
Snapping turtles feed on a variety of different animal species. Nests are often raided and the eggs of fire ants, rats,raccoons, skunks, badgers,zarigueyas, crows, coyotes and mink (9).
Some of these species are also larger than juveniles. In the water, baby turtles can be eaten by predatory fish such as perch and pike, as well as snakes (9).cranes, herons and herons also eat the babies (9).
Adult snappers are often too large for many of these predators, but alligators, black bears, and otters have been known to eat them (9).
Humans are probably the biggest predator of snapping turtles. Most states have a season when snapping turtles can be caught, trapped, and/or hunted for meat or pleasure. Snapping turtle soup is a traditional southern food.
Can a snapping turtle hurt you?
The alligator snapping turtle's bite force could potentially cut off a human finger, but it is highly unlikely that it will attack unless it feels threatened. They are safe in the water and therefore easily retreat if threatened.
On land, however, they are less mobile and tend to feel more vulnerable. It is best to keep your distance and use caution when entering shallow fresh water.
Most incidents of a snapping turtle biting a human are when they get caught and are caught to kill them.
Will snapping turtles bite you while swimming?
It is unlikely that a snapping turtle will bite you while swimming. They are more likely to swim away when they sense your presence.
They prefer shallow water, so when entering a freshwater pond or lake, you could come into contact with and accidentally step on a snapper. It can bite you if it feels threatened.
However, when you swim, snapping turtles usually do not swim or come close to you.
How do you safely pick up a snapping turtle and move it across the street?
You are likely to see snapping turtles crossing paths, especially near lakes or ponds. Many fall victim to vehicles, but you can safely pick up a snapping turtle and move it down the road.
Approach the animal from behind. Hold the turtle gently but quickly by the sides of its body, with your thumbs on top of the shell and your fingers below. Always keep your head away from your face and body.
The turtle may be heavier than you think, so be careful picking it up and keeping it low to the ground in case you drop it. Move the turtle to a safe place (near the water's edge) and gently lower it to the bottom. Walk away slowly.
Never pick up a turtle by its tail as you can cause serious injury. The tail is attached to the vertebral column.
Rescue and rehabilitation of snapping turtles
Both large organizations andHeimtierpflegerworking to save snapping turtles.
Conservation efforts are trying to address the declining populations. In 2016, a conservation program at the Nashville Zoo began breeding alligator snapping turtles until they were 3 or 4 years old.
The staff then released the turtles into the wild (8). At this age, the turtles are large enough to evade predators.

FAQs
Should you remove snapping turtles from pond? âș
Remove & Relocate
If a snapping turtle is causing problems in your pond, your best bet is to safely and humanely remove it. Grabbing its shell with your hands is a bad idea; it can easily stretch its neck back across its own shell to its hind feet and snap your fingers, and it can scratch you with its sharp claws.
