The Chinese box turtle (simplified Chinese: 食蛇龟; traditional Chinese: 食蛇龜; pinyin: shíshéguī; literally: 'Snake-eating turtle'), also known as the Yellow-margined box turtle, or Golden-headed turtle, is a species of Asian box turtle. Taxonomically, it has been called Cistoclemmys flavomarginata, Cuora flavomarginata, and Cyclemys flavomarginata. The Integrated Taxonomic Information System uses Cuora flavomarginata.

Cuora flavomarginata evelynae
C. flavomarginata has a highly domed shell, the carapace and plastron of which are a dark brown with a cream-yellow stripe on the vertebral keel. The edge of the plastron is lightly pigmented due to the marginal scutes' and plastral scutes' lighter pigmentation near their edges. The skin on the limbs is brown, while the top of the head is pale green. Each side of the head has a yellow line extending from behind the eye backward. The skin beneath the head and between the limbs is a lighter pinkish color.
The name box turtle refers to C. flavomarginata's ability to bring the plastron to the edges of the carapace. This is enabled by a hinge on the plastron and ligaments connecting the carapace and plastron, which allows for limited movement.
The forefeet have five claws, while the rear have four.
The external difference between male and female C. flavomarginata is slight. Males have a broader tail than females that is almost triangular in shape.
C. flavomarginata is found in Central China: Hunan, Henan, Anhui, Hubei, Chongqing, eastern Sichuan, Zhejiang & Jiangsu provinces (generally along the Yangtze drainage). It is also found in Taiwan and Japan, specifically the Ryukyu Islands, Ishigaki, and Iriomote.
C. flavomarginata is omnivorous, and will eat a large variety of foods. "Adults favor earthworms, frozen pinkies (defrosted), snails, slugs, and mealworms. They also eat dry trout chow and moistened dry cat food, canned cat food; fruits including strawberries, bananas, cantaloupe, and papaya; and vegetables including grated carrots, corn on the cob, and squash. Leafy greens are ignored. Invertebrates that the turtles hunt for include June bug (Phyllophaga) larvae and slugs being principal prey."
In 1863, John Edward Gray described the species as Cistoclemmys flavomarginata. It was later moved to Cyclemys, and then to Cuora. In recent issues of the Turtle Taxonomy Working Group's Checklist the species is listed as Cuora with two recognised subspecies.
Two subspecies have been recognised:
The Amboina box turtle (Cuora amboinensis), or southeast Asian box turtle is a species of Asian box turtle.
It is found in the Nicobar Islands, eastern India (Assam), Bangladesh, Myanmar, Thailand, Cambodia, Laos, central and southern Vietnam, west Malaysia, Singapore, Philippines (Leyte, Luzon, Mindanao, Samar, Negros, Panay, etc.), Indonesia (Sulawesi, Ambon Island, Sumatra, Borneo, East Malaysia, Brunei, Nias, Enggano, Simeulue, Java, Sumbawa, Halmahera, Ceram, Seram, Buru, East Timor, Bali, Palawan and Maluku), and possibly China (Guangxi and Guangdong) and Sri Lanka.
The type locality is "Amboine" (or "Amboina") Island, today Ambon Island in Indonesia.Asian box turtle
Asian box turtles are turtles of the genus Cuora in the family Geoemydidae. About 12 species are recognized. The keeled box turtle (Pyxidea mouhotii syn. Cuora mouhotii) is often included in this genus, or separated in the monotypic genus Pyxidea. Genus Cuora is distributed from China to Indonesia and the Philippines, throughout mainland Southeast Asia, and into northern India and Bhutan.Japanese pond turtle
The Japanese pond turtle (Mauremys japonica) is a species of turtle in the family Geoemydidae endemic to Japan. Its Japanese name is nihon ishigame, Japanese stone turtle. Its population has decreased somewhat due to habitat loss, but it is not yet considered a threatened species.
This species is known to hybridize with the Chinese pond turtle, the Chinese stripe-necked turtle, and the Chinese box turtle (and possibly other Geoemydidae) in captivity. As these three species are much rarer and strongly declining in the wild, this should be avoided.List of critically endangered reptiles
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 196 critically endangered reptile species, including 17 which are tagged as possibly extinct. 3.8% of all evaluated reptile species are listed as critically endangered.
The IUCN also lists 12 reptile subspecies as critically endangered.
Of the subpopulations of reptiles evaluated by the IUCN, ten species subpopulations have been assessed as critically endangered.
Additionally 910 reptile species (18% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."This is a complete list of critically endangered reptile species and subspecies evaluated by the IUCN. Species considered possibly extinct by the IUCN are marked as such. Species and subspecies which have critically endangered subpopulations (or stocks) are indicated.List of endangered and protected species of China
The endangered species of China may include any wildlife species designated for protection by the national government of China or listed as endangered by international organizations such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the International Union for Conservation of Nature (IUCN).
As one of the world's most biodiverse countries and its most populous, China is home to a significant number of wildlife species vulnerable to or in danger of local extinction due to the impact of human activity. Under the Law of the People's Republic of China on the Protection of Wildlife, the national and local governments are required to designate rare or threatened species for special protection under the law. The type of legal protection that a particular species in China enjoys may depend on the locality of administration. For example, the Beijing Municipal Government designates the red fox, wild boar, leopard cat and masked palm civet, which are found in the wilderness around the municipality, as local Class I protected species even though none are among the Class I or II protected species designated by the national government.China is a signatory country to the CITES and the national government's protected species list generally follows the designation of endangered species by CITES, but also includes certain species that are rare in the country but quite common in other parts of the world so as not to be considered globally threatened (such as moose and beaver) or are vulnerable to economic exploitation thus require legal protection (such as sable and otter). The Chinese endangered species classifications are updated relatively infrequently, and a number of species deemed to be endangered by international bodies have not yet been so recognized in China. Many listed species are endemic to the country, such as the groove-toothed flying squirrel and the Ili pika.List of endangered reptiles
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 382 endangered reptile species. 7.4% of all evaluated reptile species are listed as endangered.
The IUCN also lists nine reptile subspecies as endangered.
Of the subpopulations of reptiles evaluated by the IUCN, one species subpopulation has been assessed as endangered.
For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered reptiles are listed separately. There are 578 reptile species which are endangered or critically endangered.
Additionally 910 reptile species (18% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."This is a complete list of endangered reptile species and subspecies evaluated by the IUCN. Species and subspecies which have endangered subpopulations (or stocks) are indicated.List of introduced species
A complete list of introduced species for even quite small areas of the world would be dauntingly long. Humans have introduced more different species to new environments than any single document can hope to record. This list is generally for established species with truly wild populations— not kept domestically—that have been seen numerous times, and have breeding populations. While most introduced species can cause a negative impact to new environments they reach, some can have a positive impact, just for conservation purpose.List of invasive species in Asia
This is a list of invasive species in Asia. A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location, directly threatening agriculture and/or the local biodiversity.
The term invasive species refers to a subset of those species defined as introduced species. If a species has been introduced but remains local, and is not problematic to agriculture or to the local biodiversity, then it cannot be considered to be an invasive species and does not belong on this list.List of invasive species in Japan
A number of introduced species, some of which have become invasive species, have been added to Japan's native flora and fauna.List of reptiles of China
China has around 403 different species of reptiles that can be found in many environments including deserts, grasslands, rivers, and forests. It is the country with the seventh largest amount of different reptile species.McCord's box turtle
McCord's box turtle (Cuora mccordi ) is a species of turtle in the family Geoemydidae. The species is native to China.Ryukyu Islands
The Ryukyu Islands (琉球諸島, Ryūkyū-shotō), also known as the Nansei Islands (南西諸島, Nansei-shotō, lit. "Southwest Islands") or the Ryukyu Arc (琉球弧, Ryūkyū-ko), are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly high islands and the smaller mostly coral. The largest is Okinawa Island.
The climate of the islands ranges from humid subtropical climate (Köppen climate classification Cfa) in the north to tropical rainforest climate (Köppen climate classification Af) in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs.
The Ōsumi and Tokara Islands, the northernmost of the islands, fall under the cultural sphere of the Kyushu region of Japan; the people are ethnically Japanese and speak a variation of the Kagoshima dialect of Japanese. The Amami, Okinawa, Miyako, and Yaeyama Islands have a native population collectively called the Ryukyuan people, named for the former Ryukyu Kingdom that ruled them. The varied Ryukyuan languages are traditionally spoken on these islands, and the major islands have their own distinct languages. In modern times, the Japanese language is the primary language of the islands, with the Okinawan Japanese dialect prevalently spoken. The outlying Daitō Islands were uninhabited until the Meiji period, when their development was started mainly by people from the Izu Islands south of Tokyo, with the people there speaking the Hachijō language.
Administratively, the islands are divided into Kagoshima Prefecture (specifically the islands administered by Kagoshima District, Kumage Subprefecture/District, and Ōshima Subprefecture/District) in the north and Okinawa Prefecture in the south, with the divide between the Amami and Okinawa Islands, with the Daitō Islands part of Okinawa Prefecture. The northern (Kagoshima) islands are collectively called the Satsunan Islands, while the southern part of the chain (Okinawa Prefecture) are called the Ryukyu Islands in Chinese.Singapore Zoo
The Singapore Zoo, formerly known as the Singapore Zoological Gardens or Mandai Zoo and now commonly known locally as the Singapore Zoo, occupies 28 hectares (69 acres) on the margins of Upper Seletar Reservoir within Singapore's heavily forested central catchment area. The zoo was built at a cost of $9 million granted by the government of Singapore and opened on 27 June 1973. It is operated by Wildlife Reserves Singapore, who also manage the neighbouring Night Safari, River Safari and the Jurong Bird Park. There are about 315 species of animal in the zoo, of which some 16 percent are considered to be threatened species. The zoo attracts 1.7 million visitors each year.From the beginning, Singapore Zoo followed the modern trend of displaying animals in naturalistic, 'open' exhibits with hidden barriers, moats, and glass between the animals and visitors. It houses the largest captive colony of orangutans in the world.Wildlife of Japan
The wildlife of Japan includes its flora, fauna and natural habitats. The islands of Japan stretch a long distance from north to south and cover a wide range of climatic zones. This results in a high diversity of wildlife despite Japan's isolation from the mainland of Asia. In the north of the country, north of Blakiston's Line, there are many subarctic species which have colonized Japan from the north. In the south there are south-east Asian species, typical of tropical regions. Between these areas lies the temperate zone which shares many species with China and Korea. Japan also has many endemic species that are found nowhere else in the world.Yangtze
The Yangtze or Yangzi (English: or ) is the longest river in Asia, the third-longest in the world and the longest in the world to flow entirely within one country. It rises in the northern part of the Tibetan Plateau and flows 6,300 km (3,900 mi) in a generally easterly direction to the East China Sea. It is the sixth-largest river by discharge volume in the world. Its drainage basin comprises one-fifth of the land area of China, and is home to nearly one-third of the country's population.The Yangtze has played a major role in the history, culture and economy of China. For thousands of years, the river has been used for water, irrigation, sanitation, transportation, industry, boundary-marking and war. The prosperous Yangtze River Delta generates as much as 20% of the PRC's GDP. The Three Gorges Dam on the Yangtze is the largest hydro-electric power station in the world. In mid-2014, the Chinese government announced it was building a multi-tier transport network, comprising railways, roads and airports, to create a new economic belt alongside the river.The Yangtze flows through a wide array of ecosystems and is habitat to several endemic and endangered species including the Chinese alligator, the narrow-ridged finless porpoise, the Chinese paddlefish, the (extinct) Yangtze river dolphin or baiji, and the Yangtze sturgeon. In recent years, the river has suffered from industrial pollution, plastic pollution, agricultural run-off, siltation, and loss of wetland and lakes, which exacerbates seasonal flooding. Some sections of the river are now protected as nature reserves. A stretch of the upstream Yangtze flowing through deep gorges in western Yunnan is part of the Three Parallel Rivers of Yunnan Protected Areas, a UNESCO World Heritage Site.
