21 Types Of Turtles in Maryland

1. Common Snapping Turtle

• Scientific name: Chelydra serpentina
• Common name: Snapping Turtle
• Family: Chelydridae
• Size: 8 to 18 1/2 inches
• Lifespan: 30 to 50 years or more
• Conservation status: Least Concern

Common snapping turtles are widespread throughout Maryland. An average adult is pretty large and has a shell length of 18½ inches long.

This species has a chunky head, a long tail, and large webbed feet. The shell color is black or olive and has no distinct pattern. These Maryland snapping turtles are known for their powerful jaws—they’re so strong that these turtles eat other turtles!

You’ll find them in waterbodies with muddy bottoms. Examples include marshes, ponds, lakes, rivers, and even shallow streams. They generally prefer waters with aquatic vegetation in plenty and foods such as fish, frogs, birds, etc.

These Maryland turtles generally show docile behavior but can get quite aggressive if taken out of water. The best way to calm it is to take it back to the waters, where it feels safe.

2. Spiny Softshell Turtle

• Scientific name: Apalone spinifera
• Common name: Spiny Softshell Turtle
• Family: Trionychidae
• Size: 5 to 9 inches (males), 12 to 20 inches (females)
• Lifespan: 30 to 70 years
• Conservation status: Least Concern

The Spiny softshell turtle is a medium-to-large freshwater species that lives in Maryland’s lakes, streams, and rivers with muddy or sandy bottoms and little or no vegetation.

Female spiny softshell turtles are usually larger than males. And unlike other turtles, this species has a flexible, leather-like carapace that’s extremely rounded and flattened. The shell color can be olive grey or yellow-brown. Just like other softshell turtles, this species also has a snorkel-like snout.

The young ones feature well-defined round spots that are easily visible on the shell (though these spots become invisible as they transition to adulthood).

Spiny softshell turtles in Maryland tend to eat anything they find in the waters including crayfish, insects, small fish, and so on. They hunt by burying themselves in the mud or sand while keeping their head uncovered to grab food as it swims by.

These turtles are also able to breathe underwater by taking in oxygen through their throat skin. This is a useful adaptation given that they don’t spend a lot of time out of water.

Other adaptations of these turtles include webbed feed, long claws, and extremely flat shells that enable them to quickly swim away from predators and burry in the muddy bottom of the waters they reside in.

3. Eastern Mud Turtle

This smaller aquatic turtle species is characterized by a smooth and unmarked shell. Yes, it has an incredible plain look, with its upper shell lacking any patterns. The carapace color ranges from dark yellow to black.

The lower side of the shell is also pretty plain, though it usually appears lighter on the upper part. The key distinction of this mud turtle is the stripes on its head which can be white or yellow in color.

One particular feature that sets this turtle apart from others and makes it easily identifiable is the hinges on its lower shell which form a “K” shape when viewed from the sides.

Just as its name suggests, this turtle lives in water bodies with a soft muddy, or sandy bottom. Thus, they can be found in marshes, swamps, and rivers in Maryland.

Since the Maryland eastern mud turtle is omnivorous, it eats meat, fish, snails, insects, and aquatic vegetation as well as plant matter on land.

Unlike other turtles, eastern mud turtles do not hibernate in the cold winter months. Instead, it does the opposite—it becomes dormant in the hot months of summer (this is known as aestivation).

4. Striped Mud Turtle

• Scientific name: Kinosternon baurii
• Common name: Striped Mud Turtle, Three-Striped Mud turtle
• Family: Kinosternidae
• Size: 4 to 5 inches

The striped mud turtle is widespread throughout the sunshine state in the shallow and smaller waterbodies. You’ll most likely see them in the cypress swamps, ditches, and drainage canals in Maryland.

Striped mud turtles usually have dark-brown oval-shaped shells, with 3 yellowish vertical stripes (hence their name).

The turtle species are quite easy to spot in Maryland than other mud turtles as they spend more time on land than in water. They are unlike other mud turtles in that they sun themselves, forage for insects, and like resting out of the waters.

Maryland striped mud turtle is omnivorous and eats snails, insects, fish, algae, carrion, and even plants. The turtle has also been observed eating dried krill.

Note that this turtle species of Maryland is considered an imperiled species. Nonetheless, this small aquatic species is no longer considered under the status of Federal Endangered Status.

The turtle shell has one unique feature—a ridge traversing its entire shell length. Besides, it has another distinctive feature: two light-colored stripes on its head.

Common musk turtles of Maryland are herbivorous and will eat small aquatic or semi-aquatic animals, carrion, and aquatic vegetation. They will also feed on any other vegetation on land.

When it feels threatened, this turtle species emits a foul odor (a musky odor, hence its name). This scent can be detected in water or on land. It can also easily waft through the air to its predators.

Also, these Maryland turtles are good at climbing trees! This great capability enables them to go high up tree branches to find a safe resting place and avoid predators.
