Wood Turtle
The wood turtle (Glyptemys insculpta) is a medium-sized turtle from northeastern North America with a rough, carved-looking shell and bright orange skin on its neck and legs. It spends its life moving between clear streams and the woods and meadows beside them. Sadly, it has become rare in many places and is now an endangered species.

Where Wood Turtles Live
Wood turtles are found in southeastern Canada and the northeastern United States. Their range stretches from Nova Scotia south to northern Virginia, and west through the Great Lakes region to eastern Minnesota and northeastern Iowa. Within that range they are patchy: they live only where the right kind of stream is found.
They are semi-aquatic, which means they use both water and land. They need clean, clear streams and rivers with sandy or gravel bottoms and gentle currents. Nearby they need forests, meadows and sunny riverbanks where they can feed, bask and lay their eggs.
What Wood Turtles Look Like
A wood turtle’s top shell, or carapace, is usually about 5.5 to 8 inches (14 to 20 cm) long. It is brown or grayish-brown, and each large plate (called a scute) has rings of growth ridges that rise into a low pyramid shape. This is what gives the shell its sculpted look and the species its name, insculpta, which means “engraved”.
The neck, legs and underside of the tail are often orange or yellow-orange, especially in turtles from the eastern part of the range. The back edge of the shell is jagged, so people sometimes mistake young wood turtles for snapping turtles. But snapping turtles grow much bigger, have a long, saw-toothed tail and lack the bright orange skin.
Hatchlings look different from adults. They have plain grayish-brown shells, long tails and little of the orange color, which develops as they grow.
The wood turtle’s only close relative is the tiny bog turtle, the other member of the genus Glyptemys.
Behavior
Wood turtles are active during the day. Because they live in cool climates, they spend a lot of time basking in sunny spots to warm up, often turning to catch the sun while staying out of the wind. On very hot days they cool off in the water or in shady places.
They are known as smart, curious turtles. In lab tests they have learned to find their way through mazes about as quickly as rats. They are also famous for “stomping”: they thump the ground with their front feet, which may bring earthworms up to the surface to be eaten.
Wood turtles are omnivores. In the wild they eat worms, slugs, snails, insects, tadpoles and dead animals, along with berries, mushrooms, leaves and flowers.
Life Through the Seasons
From spring until autumn, wood turtles roam along their home stream, often traveling into nearby fields and woods to feed. As the water cools in autumn, they return to the stream to hibernate. They spend the winter underwater, resting on the bottom or tucked under riverbanks and tree roots. They do not come up to breathe; while they are cold and inactive, they can take in enough oxygen from the water through their skin. In spring they become active again and start looking for food and mates.
Breeding
Wood turtles mate in the water, mostly in spring and autumn. In late spring or early summer the female digs a nest in sandy or gravelly soil in a sunny spot, often on a sandbar or riverbank, and lays about 4 to 12 eggs.
The eggs hatch after roughly two to two and a half months, in late summer or early autumn. The hatchlings are only about 1.5 inches (3.5 to 4 cm) long. Many are eaten by raccoons, skunks, foxes and birds, which is one reason wood turtle numbers recover so slowly. Wood turtles take many years to start breeding and can live for 40 years or more.
Why Wood Turtles Are in Trouble
Wood turtles are listed as Endangered by the IUCN and are protected by law in Canada and in many U.S. states. They face many threats: loss of streamside habitat, cars on roads near streams, farm machinery in fields, predators that have become more common near people, and illegal collecting for the pet trade.
If you find a wood turtle in the wild, enjoy watching it, then leave it where it is. Never take one home. If it is crossing a road, an adult can help it across in the direction it was already heading.
Wood Turtles as Pets
Because they are protected, taking wood turtles from the wild is illegal in most places. Where keeping them is allowed, it usually needs a permit, and only captive-bred animals should ever be kept. They are not a beginner’s pet: they need a lot of space, live a very long time and need careful care. Always check your local laws and talk to an experienced reptile vet first.
Housing
A wood turtle needs a large enclosure with both a land area and a shallow water area big enough to soak and swim in. A good filter keeps the water clean. Dirty water builds up ammonia from waste, which can make turtles sick, so remove leftover food and droppings promptly and change the water often.
Diet in Captivity
Pet wood turtles do well on a varied diet like the one they eat in the wild: earthworms and nightcrawlers, insects, a little fish, quality commercial turtle food, leafy greens and some fruit such as berries, melon or apple. Avoid processed or seasoned human foods like hot dogs or leftover chicken. A vet can advise on calcium and vitamin supplements.
Lighting
Indoor turtles need a UVB lamp. UVB light helps turtles make vitamin D3, which they need to use calcium for healthy shells and bones. They also need a warm basking spot and a regular day-and-night light cycle.
Cleaning and Handling
Spot-clean every day, change the bedding regularly and clean the whole enclosure with a reptile-safe cleaner. Turtles can carry Salmonella bacteria, so always wash your hands with soap and water after touching a turtle or anything in its enclosure.
Wood turtle FAQs
What does a wood turtle look like?
It has a brown shell that looks carved, with plates that grow into low pyramids. The skin under its neck, legs and tail is orange.
Where do wood turtles live?
They live in eastern North America, from Nova Scotia to Virginia and west to the Great Lakes, Minnesota and Iowa. They stay near clean, gravelly streams.
How big are wood turtles?
The shell is about 14 to 20 centimetres (5.5 to 7.9 inches) long.
Where do wood turtles spend the winter?
They hibernate completely underwater in big streams and rivers, tucked beneath riverbank hollows and tree roots, breathing oxygen dissolved in the water.
How many eggs do wood turtles lay?
A female digs a nest in soft soil near the riverbank in spring or early summer and lays about 4 to 12 eggs. They hatch after 60 to 65 days.
