This turtle's brown carapace has three longitudinal black stripes, giving the species its common name. Chinese three-striped box turtles can have a variety of colors. The head is often golden-yellow to olive-green on the top with a brown, yellow or orange patch behind the eyes; the jaws are yellow and the neck is pink or orange. Males have indented plastrons and a thicker tail. The plastron is hinged, so the turtles can retreat inside their shells.

Its shell grows 7-12 inches (20-32 centimeters), depending on the individual.

Chinese three-striped box turtles are a semi-aquatic species found in both aquatic and terrestrial habitats. They were once found in low- to mid-elevation forests of the southern Chinese provinces of Fujian, Hong Kong, Guandong, Hainan Island, and Guangxi, as well as northern Vietnam, Laos, and Myanmar. Now, they are only known to exist in Hong Kong.

Their natural habitat includes streams and stream banks, often at high elevations. Based on observations in zoos, it is believed that Chinese three-striped box turtles spend a significant amount of time on land.

This turtle's lifespan in human care is about 30 years.

These turtles are omnivorous and eat a variety of foods, including worms, frogs, crabs, fruits, vegetation and carrion.

At the Smithsonian's National Zoo, they primarily eat greens as well as some proteins, including crickets and earthworms. Occasionally, they also eat vegetables and fruit.

According to commercial farmers on Hainan Island, China, females can produce eggs once they weigh about 2 pounds (0.75-1 kilograms). They breed both in and out of water. Males can be very aggressive while mating. Females lay two to six eggs during the nesting season, which usually happens in May, and incubation lasts 80-85 days.  

Three-striped box turtles rank ninth on the list of top 25 endangered tortoises and freshwater turtles. They are virtually extinct in the wild due to over-collection for food and medicine markets in Asia. Although there is no scientific evidence to support this, the plastron is perceived to have medicinal properties that can cure cancer.

These turtles are also becoming popular in the pet trade. There are many farms in China that raise Chinese three-striped box turtles. However, these farm-raised animals do not relieve pressures on wild populations. Many of the farmed turtles are hybrids, and these populations have a disproportionate amount of females. As a result, the farm-raised turtles are not as financially rewarding in the sale of exotic pets. A wild-caught male can worth between $20,000 and $30,000, whereas a farm-raised turtle would be sold for less.

An international coalition of organizations is now breeding genetically pure groups of these turtles as assurance colonies. In 2013, a breeding center in California was able to send five young turtles to Hong Kong in order to increase the genetic diversity of their breeding population. This marked the first time that a three-striped box turtle bred in the U.S. was able to return to its country of origin.

Many nature reserves are also being created, and Chinese three-striped box turtles are protected by law in Hong Kong. Without these increased efforts, survival of this species in the wild is doubtful.
