Turtles in Wisconsin
There are 11 species of turtles in Wisconsin, ranging from the more terrestrial Ornate Box turtle to the fully aquatic Common Snapping turtle. Some of Wisconsin's native species are unfortunately endangered or threatened, such as the Wood turtle.
Throughout this list we'll explore each of Wisconsin's native turtle species. This list can be used as a field herping guide or as a way of choosing your next pet turtle. Keep in mind that it may be illegal to possess some of these species in Wisconsin, so it's always best to research state laws regarding turtle ownership.
Clicking on the name of each turtle will take you to a comprehensive care guide that will help you prepare for owning one of these turtles. After you've decided on the species you'd like to get, try and adopt one from an animal shelter first.
If this isn't possible, then it's best to purchase a captive-bred specimen from a registered breeder rather than taking a turtle from the wild. It is illegal to take some species of turtle in Wisconsin, so make sure to familiarize yourself with the rules and regulations.
Now, without further ado, let's dive into the 11 species of turtles in Wisconsin.
1. Blanding's Turtle
Blanding's Turtle (Emydoidea blandingii) found in Worcester County, Massachusetts by Patrick Randall

Blanding's turtles are named after William Blanding, an 18th Century American naturalist. These long-lived semi-aquatic turtles have dark oval shells covered in yellow speckles, with yellow necks and plastrons that have black markings.
Although they are a species of Special Concern in Wisconsin, Blanding's turtles can be found in many areas across the state. They inhabit marshes and other wetland habitats as well as meadows. They are cautious, often diving to safety at any sign of trouble.
Blanding's turtles are omnivorous and mainly eating crustaceans, insects, and mollusks such as earthworms. They will also occasionally eat plants.
2. Ornate Box Turtle
Ornate box turtle (terrapene ornata) by Peter Paplanus
Experience Level: Intermediate to Expert
Scientific Name: Terrapine ornata

Adult Size: 3.5 to 10.5 inches (9 to 26.5 cm)
Average Price Range: $6 to $40
False Map turtles can be found in Wisconsin's main river systems and drainages with loose substrates such as gravel or sand. Although they have only been recently classified in Wisconsin, they are though to be fairly common.
To distinguish themselves from other species of Map turtles, False turtles lack colored markings on their heads. They have dark brown or black shells with the typical contour-like yellow markings of Map turtles. Most adult specimens have a pronounced keel on their backs.
False Map turtles are omnivorous and eat aquatic insects, crustaceans, mollusks, and aquatic plants. They rarely travel far from the water and like to bask on outcrops above the surface.
4. Northern Map Turtle
Common Map Turtle (Graptemys geographica) basking on rocky shoreside
Scientific Name: Graptemys geographica
Other Names: Common Map turtle
Adult Size: 4 to 10.5 inches (10 to 26.5 cm)
Northern Map turtles are an aquatic species commonly found in Wisconsin's major river systems. These turtles are accomplished swimmers and like to bask above the surface of the water.
Northern Map turtles have dark brown or olive green shells with yellowish markings which resemble the contours of a map. Small yellow spots behind the eyes distinguish the Northern Map turtle from other subspecies.
These turtles are mainly carnivorous, feeding on aquatic insects, crustaceans, small fish, and mollusks. They may also eat plants occasionally.
5. Ouachita Map Turtle
Ouachita Map Turlte (Graptemys ouachitensis) on white background
Scientific Name: Graptemys ouachitensis
Other Names: Southern Map turtle
Adult Size: 3.5 to 10 inches (9 to 25.5 cm)
Average Price Range: $40 to $100
Also known as Southern Map turtles, Ouachita Map turtles are relatively common in the rivers of Wisconsin's southern and southwestern regions. They are active during the day and like to bask, but are easily startled and will quickly jump into the safety of the water.
Ouachita Map turtles can be distinguished from other Map turtles by the large lightly colored patches behind their eyes. These Map turtles also have dark patches outlined in yellow contour-like markings on the scutes of their dark or olive green shells. Males have a prominent serrated keel protruding from their backs.
As with many other turtles, Ouachita Map turtles are omnivores. They mainly eat crustaceans, insects, and mollusks. They will also occasionally eat algae and aquatic plants.
6. Eastern Musk Turtle
Eastern Musk Turtle also known as the common musk (Sternotherus odoratus) sitting on deck by Alan Wolf taken in Michigan
Family: Kinosternidae
Scientific Name: Sternotherus odoratus
Other Names: Common Musk turtle, Stinkpot
Lifespan: 50+ years
Eastern Musk turtles are commonly known as "Stinkpots" because of the strong odor they can excrete from their musk glands to deter predators. Eastern Musk turtles are one of North America's smallest aquatic freshwater turtles and can be found in southeastern parts of Wisconsin.
Eastern Musk turtles have dark brown or black unmarked shells. They have two yellowy stripes running down their dark heads as well as fleshy barbels on their chins and necks. This species prefers slow-moving waters in boggy or marshy areas with dense fronds of aquatic vegetation.
These nocturnal omnivores mainly eat small amphibians, crustaceans, and mollusks. They are considered common in Wisconsin.
7. Painted Turtles
Midland Painted Turtle (Chrysemys picta marginata) found in Clark County, Missouri by Peter Palanus
Scientific Name: Chrysemys picta marginata (Midland Painted), Chrysemys picta belli (Western Painted)
Adult Size: 4 to 10 inches (10 to 25.5 cm)
There are two subspecies of Painted turtles found in Wisconsin; the Midland Painted turtle and the Western Painted turtle. These two species are some of the most common turtles in Wisconsin, with the Western Painted turtles inhabiting northwestern and western regions and Midland Painted turtles found in Wisconsin's other areas.
Painted turtles have dark brown to black shells that usually have yellow to red coloration around the edge. Midland Painted turtles have plain yellow plastrons, while the slightly larger Western Painted turtles sport a series of green, brown, and blue markings on their red plastrons. Both species have brown skin with yellow stripe markings on their faces and necks.
These medium-sized aquatic turtles are diurnal and prefer shallow waters such as marshes and ponds and can often be seen basking on logs beside the water. Both subspecies in Wisconsin are omnivores, consuming small amphibians, insects, mollusks, and vegetation.
8. Common Snapping Turtle
Common snapping (Chelydra serpentina) turtle walking in Bombay Hook National Wildlife Refuge. Delaware
Family: Chelydridae
Scientific Name: Chelydra serpentina
Other Names: Common Snapper, Eastern Snapping turtle, Snapper
Adult Size: 8 to 20 inches (20 to 51 cm)
Common Snapping turtles are the largest species found in Wisconsin and are found in larger bodies of water across the state, such as lakes and reservoirs. Common Snappers are one of the biggest heavyweights in Wisconsin's freshwater food chain.
Easily identified thanks to their powerful hooked jaws, Common Snappers have dark brown or green shells with ridges on the carapace. These large turtles have long saw-toothed tails and sharp claws. If captured on land, this species can hiss aggressively and will attempt to bite.
Common Snapping turtles are nocturnal omnivores that consume amphibians, fish, smaller reptiles and turtles, and even waterfowl. They may also eat vegetation from time to time.
9. Smooth Softshell Turtle
Smooth Softshell Turtle (Apalone Mutica)
Family: Trionychidae
Scientific Name: Apalone mutica
Other Names: Spineless Softshell
Adult Size: 4.5 to 14 inches (11.5 to 35.5 cm)
Smooth Softshells are a medium to large species of aquatic turtle that has Special Concern status in Wisconsin. Smooth Softshells are currently found in just a few scattered southwestern counties, where they inhabit rivers with sandy or silty bottoms.
Smooth Softshells resemble leathery pancakes with cream to white plastrons. Their shells are usually brown or gray, and they have distinctive lines running from behind their eyes. Smooth Softshells have tapered snouts which they use as snorkels while waiting to catch prey.
These aquatic turtles usually bury themselves in shallow sands to ambush aquatic insects, crustaceans, and mollusks. Due to the habitat loss of areas with nesting sandbars, Smooth Softshells are in a vulnerable position.
10. Spiny Softshell Turtle
Spiny Softshell Turtle (Apalone spinifera) on asphalt
Scientific Name: Apalone spinifera
Adult Size: 5 to 17 inches (12.5 to 43 cm)
Spiny Softshells are the most commonly encountered type of Softshell in Wisconsin and can be found across most of the state. They prefer rivers and streams with a faster-moving current and are skilled swimmers.
Spiny Softshells have a leathery pancake-shaped green shells that feel a bit like sandpaper and sport a series of spines along the front edge. They also have dark spot markings on their soft carapaces. They have long, tapered beaks which they use to breathe while buried in the sand waiting to ambush their prey.
These Softshells are carnivores and will feed on any crustaceans, insects, and mollusks that swim past their hiding place. They then lunge forwards and grab the prey in their mouths.
11. Wood Turtle
Wood Turtle (Glyptemys insculpta) in woods on gravel
Scientific Name: Glyptemys insculpta
Adult Size: 5.5 to 8 inches (14 to 20 cm)
Wood turtles are an intelligent, largely terrestrial species that inhabits grasslands and woodland areas close to rivers and streams. This species is Threatened in Wisconsin due to habitat loss. That said, they have been recorded as being seen in most areas of the state.
Wood turtles get their name from their dark brown shells, which have a rough, grainy texture and scutes that look as if they have been sculpted from wood. These turtles have markings that appear similar to the growth rings and wood grain of trees.
These diurnal omnivores roam a fair distance each day while looking for berries, earthworms, insects, mollusks, and plants to eat.
