The United States is home to more turtle species than any other country in the world, almost 100 species, and subspecies. But those turtle species are not distributed evenly, so most states won’t always be home to the same turtle species, even if they are very close.
Minnesota is home to 10 turtle species. In this article I am going to take a closer look at each species and cover a few basic things about them, things like the appearance, lifespan, how big it can get, diet, where it lives, conservation status, and reproduction.
Quick list of the native turtles of Minnesota:
- Blanding’s Turtle Emydoidea blandingii
- Common Map Turtle Graptemys geographica
- Common Snapping Turtle Chelydra serpentina serpentina
- Eastern Spiny Softshell Apalone spinifera spinifera
- False Map Turtle Graptemys pseudogeographica pseudogeographica
- Midland Smooth Softshell Apalone mutica mutica
- Ouachita Map Turtle Graptemys ouachitensis ouachitensis
- Western Painted Turtle Chrysemys picta bellii
- Western Spiny Softshell Apalone spinifera hartwegi
- Wood Turtle Glyptemys insculpta
Now let’s take a closer look at the native turtles of Minnesota.
The Native Turtles of Minnesota
Quick Note: Most turtle subspecies are very similar, so besides some few differences in color it’s possible that everything else about them to be the same.
Quick Note: In this list I am also going to tell you the conservation status of the species, meaning how close they are to extinction. I will give a more in-depth explanation of this ranking works, at the end of the article, but until then I will add a picture that will let you know the basics.
Blanding’s Turtle (Emydoidea blandingii)
Description: Blanding’s Turtle has a considerably more dome-like shaped shell than most turtles. The upper part of the shell is usually colored dark brown or black. The lower part of the shell is usually yellow with a multitude of black patterns. The skin is usually dark brown or yellow, with the exception of the neck which is yellow.
How long it can live: Between 60 and 80 years.
How big it can get: Blanding’s turtle reaches sizes between 7 and 10 inches.
Where it lives: Blanding’s turtles usually inhabit clean shallow waters with soft bottoms and abundant vegetation. So they can be typically be seen in marshes, creeks, small lakes, and ponds.
Diet: They are omnivorous, which means that their diet is made out of a variety of things like meat, fish, insects, snails, fruits, vegetables, and aquatic vegetation.
Conservation Status: Endangered
Reproduction: Nesting occurs from late May until the middle of July, and the incubation period lasts between 70 and 90 days.
Common Map Turtle (Graptemys geographica)
Description: The Common Map Turtle Usually ranges in color from dark brown to black. On the upper part of the shell, they have a map-like pattern that is lightly colored, and a row of saw-toothed knobs running down the center of the shell. As the map turtles get older the pattern and the knobs start to slowly disappear, up to a point where they are barely visible. The bottom part of the shell is usually light-colored. The skin is usually covered with long and thin stripes that are also light-colored.
How long it can live: Between 30 and 50 years.
How big it can get: Males usually reach sizes between 3 and 5 inches, while females are considerably bigger, reaching sizes between 8 and 10 inches.
Where it lives: Map turtles can be found in waters that are stagnant or slow-moving, and that has a lot of vegetation. So they can be usually seen in rivers, slow-moving streams, lakes, and ponds.
Diet: Map turtles are omnivorous, so they will eat meat, insects, fruit, vegetables, aquatic vegetation, and everything else that they can find.
Conservation Status: Least Concern
Reproduction: Map turtles usually nest multiple times a year from the start of the spring up until the end of the summer.

Where it lives: A habitat generalist, the common snapping turtle can be found in almost any body of freshwater with a muddy bottom.
Diet: They are omnivorous, which means that they eat both meat and plants. When it comes to the meat they will scavenge, or actively hunt their prey in the water.
Conservation Status: Least Concern
Reproduction: Nesting season is May to July. Incubation usually lasts between 70 and 100 days.
Eastern Spiny Softshell (Apalone spinifera)
Description: The Eastern Spiny Softshell has a leather-like shell that is very round and flattened when comparing it to other turtles. The colors usually range from olive-gray to yellow-brown. In the case of younger individuals, well-defined round spots can be observed on the shell, in the case of adults those spots are not very visible. Like most softshell turtles they also have a snorkel-like snout.

Diet: Eastern Spiny softshells are carnivorous. Their preferred prey includes fish, crayfish, and other aquatic invertebrates.
Conservation Status: Least Concern
Reproduction: Nesting season starts in March and ends in late May, early June. The amount of time it takes the eggs to hatch is around 80 days.
False Map Turtle (Graptemys pseudogeographica)
Description: The color of the shell is usually olive, brown, or black with dark blotches that have yellow lines around them. The upper shell has lies that sometimes form a web-like pattern and may or may not have blotches, this is where it gets the name False Map Turtle because the lines form a sort of map across the shell, but not like map turtles have. The bottom of the shell is usually colored yellow. The skin of the False Map Turtle is usually covered with thin yellow-white stripes.
How long it can live: Between 30 and 50 years.
How big it can get: Males usually reach sizes between 3 and 5 inches, while females are considerably bigger, reaching sizes between 8 and 10 inches.
Where it lives: Map turtles can be found in waters that are stagnant or slow-moving, and that has a lot of vegetation. So they can be usually seen in rivers, slow-moving streams, lakes, and ponds.
Diet: Map turtles are omnivorous, so they will eat meat, insects, fruit, vegetables, aquatic vegetation, and everything else that they can find.
Conservation Status: Least Concern
Reproduction: Map turtles usually nest multiple times a year from the start of the spring up until the end of the summer.

The Conservation Status
The conservation status of a species shows how close a species is to extinction. When a species gets its status there are a lot of factors taken into consideration, not only the number of individuals still leaving.
Even if at the moment there are a lot of individuals of a species, there can be some changes in their environment that will drastically affect the species. For example, the plastic in the water is greatly impacting sea turtles in a negative way.
There are a lot of systems that track the conservation status of a species, but the most well-known and used is the one I used in this article, the IUCN Red List of Threatened Species. With this system species are classified into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Out of the nine classifications, two of them basically mean that there is not enough data on the species, so you will usually see only seven possible statuses instead of nine.
Here is a list that explains what every status means:
- Extinct (EX) – No known living individuals
- Extinct in the wild (EW) – Known only to survive in captivity, or as a naturalized population outside its historic range
- Critically endangered (CR) – Extremely high risk of extinction in the wild
- Endangered (EN) – High risk of extinction in the wild
- Vulnerable (VU) – High risk of endangerment in the wild
- Near threatened (NT) – Likely to become endangered in the near future
- Least concern (LC) – Lowest risk; does not qualify for a higher risk category. Widespread and abundant taxa are included in this category.
- Data deficient (DD) – Not enough data to make an assessment of its risk of extinction
- Not evaluated (NE) – Has not yet been evaluated against the criteria.
Alien Species of Minnesota
The turtle species that I listed above are known as native species, but there can be other turtle species that live in that area that are not native, those species are called alien species.
Alien species are species that are not native to an area, but they still live there. Those species are usually brought to that region by humans. So a certain state might be home to 10 turtle species, but only 5 of them can be native.
Alien species can be added to an area to help with certain ecological problems, or by mistake. Turtles can do a lot of good things to an area, they can keep certain insect populations under control, they can eat the overwhelming vegetation, of a lake, that got out of control, and there are a lot of other beneficial things that they can do.
It’s also possible that some unknowing person decided to release a few turtles into the wild. If those turtles manage to reproduce, they can easily start a new alien species in a new area. Overall I strongly suggest you not do this, it can be very dangerous for the ecosystem and for the turtles as well. If you want to know more reasons why you shouldn’t do this, you should read my article: Can Pet Turtle Survive in the Wild? In this article I explore all the possible outcomes of this situation.
Minnesota State Laws Regarding Turtles
Every state in the US has different laws regarding native turtles and turtles in general. Most of those rules are generally designed to protect turtles, so even if they seem a little restrictive, they are there for a good reason. Minnesota has its own set of laws that are different from any other state. Since a lot of those laws are about the native species I strongly suggest you visit this interactive map that will point you to an article on this site that explains as simply as possible the state laws in Minnesota regarding turtles, tortoises, and terrapins.
What to Do If You Find a Wild Native Turtle
What you can do if you find a native wild turtle really depends on your intentions. If you want to take a few photos from a distance, you can definitely do that. If you want to touch the turtle you can usually do that, but you have to take a few cautionary measures.
You have to remember that most wild animals can carry bacteria, and since turtles spend a lot of time in water those bacteria can be a little more dangerous. So if you touch a turtle make sure that you have some wet wipes near you, if you don’t you should probably avoid touching it. But if you still want to, at least try not to put your hands near your face after you touched the turtle.
The most important thing that you have to watch out for when interacting with a wild turtle is the turtle trying to bite you. Generally, turtles are peaceful creatures, but if they think that they are in danger and they have no way of escaping, then they will definitely try to bite you. To prevent this make sure that you don’t let it too close to your toes (if they are exposed), or to your fingers. If you want to pick up a turtle you should catch it by the sides and keep your hands above or below it, never in front of its mouth.
If you want to feed the turtle, you can definitely do that, that would actually be great, but make sure that you are feeding it the right thing, some foods can be very dangerous to turtles, to find out which food items are good and which are bad you can always check out this article where you will also find a few food items lists: What Do Turtles Eat? ( Including Food Lists )
If you want to take the turtle home as a pet, you first have to make sure that it’s legal to do so. Most states, including Minnesota, have laws that protect wild native turtles. You can check out the laws of Minnesota on this page: Turtle State Laws.
If it’s winter or close to winter there is a chance that you can find a hibernating turtle. When turtles hibernate, they enter a very profound sleep which allows them to conserve energy. They generally do this because during cold seasons there is little to no food available to them, and because there is no heat to allow them to heat up their body ( turtles are unable to produce their own body heat). If during a cold season you find a turtle that is hibernating, usually the best thing that you can do is to leave it to hibernate peacefully. Usually, turtles know how to choose a good spot to hibernate, so they are probably just fine. If you want to know more about turtle hibernation, I’ve written a more in-depth article that covers the subject, In this article, I cover why turtles hibernate, how hibernation takes place, how aquatic turtles hibernate, how land turtles hibernate, how sea turtles hibernate, what is brumation, and many other important and interesting things about hibernation: Do Turtles Hibernate?
Conclusion
This article should cover every basic thing about the native turtles of Minnesota. But if you have a question about something that you couldn’t find in the article you should leave a comment, I will do my best to answer it as soon as possible.

Hey Victor,
So mowing my yard yesterday I found what looks to be a Western Painted turtle in the middle of the yard. Upon close inspection it was burying eggs. Once done, the thing ran off.. . . I was amazed at its speed. I posted a picture on Facebook and got a response that I was curious about. They said: “In 60 days you’ll be knee deep in baby turtles, you might want to do something to protect the eggs from other animals.” What type of predator would go after the buried eggs and how would I protect these things? Wouldn’t it be better to let be ?
Hello Russell,
Turtles usually look for safe spots to lay their eggs, so your yard must be quite safe.
You could let the eggs where they are, or you could take them out carefully and make an incubator for them (it’s not as hard as it sounds). If you want to take care of the eggs check out this article: How to Take Care of Turtle Eggs (Easy Guide With Pictures), here you will find all the information that you need. And if you want to move the eggs to a safer place you can always follow just the instructions in the beginning.
