# Eastern Box Turtle (*Terrapene carolina*)

> The eastern box turtle (Terrapene carolina) is a small, land-dwelling turtle of the eastern United States, known for the hinged shell it can close like a box for protection. It lives in woodlands, meadows, and wetlands, eating insects, fruit, mushrooms, and carrion. Barely 15 cm long and weighing around half a kilogram, it is a famously slow, long-lived reptile that can survive 50 to 100 years. The IUCN lists it as Vulnerable.

## The hinged shell

The box turtle takes its name from the hinge across its lower shell, or plastron, which lets it fold the front and back sections tightly shut. Pulled into its high-domed shell, the turtle can seal itself completely inside, leaving no soft parts exposed to a predator. This living armour is its main defence, since it is far too slow to flee from danger. The shell also bears colourful yellow or orange markings that vary from turtle to turtle.

## Diet and feeding

Eastern box turtles are omnivores with a varied appetite that changes as they grow. Young turtles lean heavily towards animal prey such as insects, worms, and snails, while adults eat more plant matter, including fruit and mushrooms. They will also scavenge carrion when they find it. Remarkably, box turtles can eat certain fungi that are toxic to humans without coming to harm.

## Habitat and home range

The species lives in the woodlands, meadows, and wetlands of the eastern United States, favouring moist, leafy ground with plenty of cover. Individual turtles are strongly tied to a small home range, often only a few hectares, which they may occupy for their entire lives. This deep attachment to home means a turtle moved far away will try to travel back, frequently dying on roads in the attempt. On hot days they shelter in leaf litter, logs, or shallow pools to stay cool and moist.

## Longevity and reproduction

Box turtles are among the longest-lived of small reptiles, commonly reaching 50 years and sometimes approaching a century. They mature slowly, often taking several years to reach breeding age. After mating, the female digs a nest in soft soil and lays a small clutch of eggs, then leaves them to incubate unattended. Only a few hatchlings survive to adulthood, so the loss of even a handful of breeding adults can hurt a population.

## Hibernation

In the colder parts of its range, the eastern box turtle spends winter in a state of dormancy. As temperatures drop it burrows into loose soil, leaf litter, or the mud of pond edges and slows its body down to survive the freeze. It can even tolerate small amounts of ice forming in its tissues without dying. When the ground warms in spring, the turtle emerges to resume feeding and breeding.

## Why it is Vulnerable

The eastern box turtle is listed as Vulnerable by the IUCN, and its slow life history makes it hard to recover from losses. Habitat destruction, road deaths, and collection for the pet trade all take a steady toll on wild populations. Because the turtles breed slowly and rely on many years of adult survival, even modest ongoing losses cause long-term decline. Keeping woodland habitats connected and leaving wild turtles where they are found both help the species persist.

## Frequently asked questions

### Why is it called a box turtle?

It is named for the hinge across its lower shell, which lets the turtle fold the shell shut like a box. Sealed inside its high-domed shell, it can hide every soft part from predators, its main defence against attack.

### What do eastern box turtles eat?

They are omnivores. Young turtles eat mostly insects, worms, and snails, while adults take more fruit and mushrooms, and both will scavenge carrion. They can safely eat some fungi that are poisonous to people.

### How long do box turtles live?

Eastern box turtles are remarkably long-lived, commonly reaching 50 years and sometimes nearing 100. They grow and mature slowly, so a wild population depends on adults surviving for many decades.

### How big do eastern box turtles get?

They are small turtles, only about 15 cm long and weighing roughly 0.3 to 0.6 kg. Their shell is distinctively high and domed, marked with variable yellow or orange patterns.

### Why should you not move a box turtle?

Box turtles are strongly attached to a small home range they may keep for life. A turtle carried away will try to return, often dying on roads in the attempt, so wild ones are best left exactly where they are found.

### Are eastern box turtles endangered?

They are listed as Vulnerable by the IUCN. Habitat loss, road deaths, and collection for the pet trade steadily reduce their numbers, and their very slow breeding makes recovery from these losses difficult.
