Maryland is home to a diverse array of turtle species, from common backyard visitors to rare finds. Whether you’re a nature lover, a student, or a wildlife enthusiast, understanding the different types of turtles in Maryland can deepen your appreciation for local biodiversity. This list covers the most prevalent and notable turtle species found throughout the state, providing detailed descriptions to help identify and learn about each one.
Eastern Box Turtle (Terrapene carolina carolina)
The Eastern Box Turtle is Maryland’s most recognizable terrestrial turtle, distinguished by its domed shell and vibrant color pattern. Its carapace features intricate yellow and orange markings on a dark background, making it easy to identify. These turtles are primarily found in moist woodlands and grasslands, where they forage for insects, berries, and fungi. Their ability to close their shells completely for protection makes them a fascinating species worth observing and protecting.
Painted Turtle (Chrysemys picta)
The Painted Turtle is a common freshwater turtle seen in ponds, lakes, and slow-moving streams across Maryland. It boasts a smooth, oval shell with bright red and yellow markings along the edge, giving it an eye-catching appearance. Painted Turtles are excellent swimmers, often basking on logs or rocks near the water’s edge. They feed primarily on aquatic insects, small fish, and vegetation, making them an important part of the aquatic ecosystem.
Red-Eared Slider (Trachemys scripta elegans)
Often kept as pets, the Red-Eared Slider is frequently seen in Maryland’s freshwater habitats. They are easily recognized by the distinctive red patch behind each eye and their greenish shell with yellow stripes. These turtles are semi-aquatic, spending much of their time basking on logs or swimming in ponds and rivers. Due to releases by pet owners, they are now widespread and sometimes outcompete native species.
Common Musk Turtle (Sternotherus odoratus)
Also known as the Stinkpot, the Common Musk Turtle inhabits shallow waters, swamps, and wetlands throughout Maryland. It has a small, dark shell with subtle yellow markings and a pointed snout. This turtle gets its name from the foul-smelling musk it releases when threatened, a defense mechanism. They are primarily bottom-dwellers, feeding on small invertebrates, insects, and carrion.
Diamondback Terrapin (Malaclemys terrapin)
Unique to brackish coastal waters, the Diamondback Terrapin is Maryland’s state reptile and a true estuarine specialist. Its striking shell features a series of diamond-shaped patterns in black and yellow, providing excellent camouflage. These turtles are often found in the Chesapeake Bay and tidal creeks, feeding on mollusks and crustaceans. Conservation efforts are ongoing to protect this species from habitat loss and overharvesting.
Spotted Turtle (Clemmys guttata)
The Spotted Turtle is a relatively rare species in Maryland, distinguished by its dark shell dotted with bright yellow spots. It prefers wetland habitats such as marshes and vernal pools, often hiding beneath leaf litter. Spotted Turtles are primarily herbivorous, feeding on aquatic vegetation and small invertebrates. Due to their limited range, they are protected and considered a species of concern.
Blanding’s Turtle (Emydoidea blandingii)
Blanding’s Turtle is a semi-aquatic species with a domed, black shell and a distinctive yellow chin and throat. It favors shallow ponds, marshes, and wet meadows in Maryland, often burrowing in the soft substrate. Known for its gentle demeanor, Blanding’s Turtle feeds on aquatic insects, crustaceans, and plant material. Conservation efforts focus on habitat preservation, as their populations are declining due to habitat destruction.
Northern Map Turtle (Graptemys geographica)
The Northern Map Turtle is a freshwater species found in Maryland’s rivers and streams, especially in the Potomac River. Its shell has intricate yellowish-green markings resembling contour lines on a map, which aid in identification. These turtles are strong swimmers, basking on rocks or logs in the water. They primarily feed on mollusks and aquatic insects, contributing to the health of river ecosystems.
Cooper’s Turtle (Glyptemys muhlenbergii)
One of Maryland’s rarest and most endangered species, Cooper’s Turtle is a small, semi-aquatic turtle with a high-domed shell and striking yellow markings on a dark background. It inhabits rocky streams and wooded wetlands, often hiding among leaf litter and stones. Due to habitat loss and collection, Cooper’s Turtle is critically protected, and sightings are considered significant for conservation efforts.
How to Choose
When selecting a turtle to observe or potentially care for, consider habitat compatibility, size, and behavior. Native species like the Eastern Box Turtle or Painted Turtle are better suited for local environments, while non-native species like the Red-Eared Slider may outcompete native wildlife if released into the wild. Always prioritize species that are legally protected or of conservation concern, and ensure any interactions are responsible and sustainable.
