15 Species of Turtles in Arkansas (Pictures)

Arkansas is home to several turtle species, each with their own unique characteristics and behaviors. From the large and impressive alligator snapping turtle to the colorful and distinctively patterned painted turtles, these reptiles play an important role in the state’s aquatic ecosystems. Whether swimming in rivers and streams, basking on rocks and logs, or foraging for food in the water, these animals can be found throughout the state. This article discusses 15 turtles found in Arkansas.

15 Turtles in Arkansas

1. Common Snapping Turtle

Scientific Name: Chelydra serpentina

The Common snapping turtles are one of the largest freshwater turtles in North America. They can grow up to 18 inches in length and weigh up to 35 pounds.

They have a rough, knobby shell and a long, pointed tail. Their powerful jaws and sharp beaks allow them to crush and tear their food, including fish, frogs, snakes, and even small mammals.

In Arkansas, the common snapping turtle can be found in slow-moving rivers, lakes, ponds, and swamps. They are typically found in areas with soft, muddy bottoms where they can bury themselves and lie in wait for prey.

2.  Alligator Snapping Turtle

Scientific Name: Macrochelys temminckii

Alligator snapping turtles are large, prehistoric-looking freshwater turtles found throughout much of Arkansas. These large turtles can weigh up to 200 pounds and measure up to 2.5 feet long.

Despite their name, alligator snapping turtles are not related to alligators but are named for their resemblance to the reptile. They have a rough, ridged shell resembling the back of an alligator, a long tail, and a large head with a hooked beak.

3. Southern Painted Turtle

Scientific Name: Chrysemys dorsalis

Southern painted turtles are brightly colored, with red, yellow, or orange on their heads, legs, and shells. They are found throughout the southeastern United States, including Arkansas, and prefer slow-moving or still water with plenty of vegetation.

They also need plenty of places to bask in the sun because they do this to regulate their body temperature. These medium-sized turtles grow to be around 6 inches long, and the females are larger than the males. 

4. Western Chicken Turtle

While present in Arkansas, the Western chicken turtle is the least common aquatic turtle in the state. These turtles are often confused with red-eared sliders, but they are easily recognized if you take a closer look. Western chicken turtles have a broad yellow bar across each front leg and vertical yellow stripes under their shell in the back. 

5. Northern Map Turtle

Of the 16 species of turtles in Arkansas, the ornate box turtle is one of two that are land turtles rather than aquatic. This specie can be found in the Arkansas River Valley ecoregion, northwestern Arkansas, and the Grand Prairie region of the Delta.

As the name suggests, three-toed box turtles have three toes on each hind foot, unlike other box turtle species, which have four toes. They have a domed, brown or black shell marked with yellow or orange lines and spots. This species hibernates during the winter, digging burrows and spending the colder month underground.

Red-eared sliders are native to Arkansas rather than being introduced like they are in many other states in the US. This species is actually one of the most common turtles in Arkansas and is found in a variety of aquatic habitats, including rivers, lakes, ponds, and marshes. Red-eared sliders are easily identifiable by the red stripe behind each eye and the green, olive, or brown shell with yellow markings.

Scientific Name: Sternotherus carinatus

The razor-backed musk turtle is named for the sharp keel, or ridge, on its shell, which resembles a razorback. Like other musk turtles, this species releases a unique musky odor, possibly as a defense mechanism.

These small turtles grow between 3 to 4 inches in length and are popular in the pet trade. However, they require specialized care and should only be kept by experienced turtle keepers. 

14. Midland Smooth Softshell

Scientific Name: Apalone mutica mutica

The Midland smooth softshell turtle is a relatively large species of turtle, with adults typically measuring between 8-16 inches in length. These turtles have smooth, flat, soft shells that are gray or brown, with a lighter-colored belly.

Scientific Name: Apalone spinifera ssp.

The Spiny softshell turtle gets its name from the spiny projections on the front of its shell. These projections are not found in young turtles and become more pronounced as the turtle gets older.

They have a flat, streamlined shell, which is covered in leathery skin instead of the hard, bony plates found on most turtles. This allows the Spiny softshell turtle to be more agile in the water. These turtles have a long, pointed snout, which they use to probe in the mud and sand for prey.
