Blanding's Turtle

Emydoidea blandingii

Conservation
Ohio threatened
What the sources say

Habitat: Ohio’s Blanding’s turtles are limited primarily to the northern counties along Lake Erie, where they inhabit the marshy shorelines, inland streams, wet meadows, and swamp forests. Although essentially aquatic, the Blanding’s turtle often travels over- land as it moves among different wetlands throughout the year. (Ohio Department of Natural Resources, Division of Wildlife)

Eastern Musk Turtle

Sternotherus odoratus

41 records by month.
What the sources say

Habitat: Musk turtles seem to prefer deep, still water in lakes, ponds, and sluggish streams with muddy bottoms and an abundance of plant life. Like snapping turtles, musk turtles are strongly aquatic and are seldom observed out of water except to lay eggs, or occasionally during early spring to bask in the sun.

Eastern Spiny Softshell

Apalone spinifera spinifera

Conservation
common/game
What the sources say

Habitat: Although it can be found in lakes and smaller streams, the Eastern spiny softshell is essentially a river turtle. It prefers relatively shallow water with a sand or soft mud bottom. A common habit of the softshell is to settle on the bottom by rocking from side to side, while flipping sand and mud up onto its back, com- pletely burying itself.PHOTO BY: ©MATT JEPPSON (Ohio Department of Natural Resources, Division of Wildlife)

Midland Painted Turtle

Chrysemys picta marginata

What the sources say

Habitat: They are particularly fond of basking and can be seen by the dozens on logs and along the banks of most bodies of water through the summer and even during warm winter days. With the coming of winter, midland painted turtles seek deep water and burrow into the mud or debris at the bottom. (Ohio Department of Natural Resources, Division of Wildlife)

Apalone mutica mutica

Conservation
common/game
What the sources say

Habitat: The midland smooth softshell is limited primarily to southern and southeastern Ohio where it inhabits the larger tributaries of the Ohio River, particularly the Scioto River. They are especially fond of shallow water areas along sandbars. Juvenile (Ohio Department of Natural Resources, Division of Wildlife)

Northern Map Turtle

Graptemys geographica

What the sources say

Habitat: Map turtles are extremely wary and show a marked preference for sizable bodies of deep water, such as large rivers and lakes, where they can dive to the safety of the depths. The broad, flat crushing surfaces of the powerful jaws are well suited for consuming snails, crayfish, and clams, which form the bulk of the diet. Map turtles may be active year-round.

Ouachita Map Turtle

Graptemys ouachitensis

Conservation
Ohio species of concern
What the sources say

Habitat: Previously thought to be limited to the lower reaches of the Scioto River, recent surveys reported the Ouachita map turtle in the Muskingum and Great Miami Rivers, indicating its distribution may be more widespread.PHOTO BY: ©SHUTTERSTOCK.COM (Ohio Department of Natural Resources, Division of Wildlife)

Red-eared Slider

Trachemys scripta elegans

What the sources say

Habitat: Although these turtles are common in areas far south of Ohio, isolated communities have been discovered in some northern states. Whether released captives or remnants of an ancient popu- lation from a warmer age, they manage to hold their own. This turtle is also fond of basking and can be seen on logs and along the banks of many types of bodies of water through the summer.PHOTOS BY: ©NINA HARFMANN Red-ear detail (Ohio Department of Natural Resources, Division of Wildlife)

Snapping Turtle

Chelydra serpentina

Size
Upper shell usually 8 to 14 inches, occasionally to nearly 20; usually 10 to 35 lb, occasionally to 75 lb in the wild.
How to recognize it
  • Large head, long tail
  • Saw-toothed scales on the long tail
  • Small, cross-shaped lower shell
Conservation
common/game
517 records by month.
What the sources say

Habitat: Found in permanent bodies of water, as well as ephemeral wetlands and ditches. Snappers seldom bask in the sun except in early spring; therefore, though they are very abundant they are not seen as frequently as most other turtles. From May through June, females may be seen crossing roads in search of sites to lay their eggs. (Ohio Department of Natural Resources, Division of Wildlife)

Spotted Turtle

Clemmys guttata

Conservation
Ohio threatened
What the sources say

Habitat: This handsome turtle shows a marked preference for the shallow, sluggish waters of wet prairies and meadows, fens, bogs, marshes, small streams, ditches, and pond edges, especially where vegetation is abundant. It occasion- ally wanders away from water and lives in wet woods. (Ohio Department of Natural Resources, Division of Wildlife)

Woodland Box Turtle

Terrapene carolina carolina

Conservation
Ohio species of concern
What the sources say

Habitat: Found in woodlands throughout Ohio, the box turtle is our most terrestrial turtle. During the heat of summer, this docile animal spends the day hidden beneath rotting logs, decaying leaves, and other plant debris, ven- turing out only during early morn- ing or evening. A sudden shower after a dry spell will usually bring out box turtles in large numbers.PHOTO BY: ©NINA HARFMANN (Ohio Department of Natural Resources, Division of Wildlife)
