The golden coin turtle (Cuora trifasciata), also known commonly as the Chinese three-banded box turtle and the Chinese three-striped box turtle, is a species of turtle in the family Geoemydidae. The species is native to southern China.[3] There are two recognized subspecies.

Geographic range

C. trifasciata is distributed in China, but only on the island of

extirpated from the mainland Guangdong, Guangxi, and Fujian provinces), as well as Hong Kong.[3] The populations from Vietnam and Laos are now regarded as a separate species, the Vietnamese three-striped box turtle (C. cyclornata).[5]

Description

Plastron

C. trifasciata has three distinct black stripes on its brown

plastron
is mostly black with a yellow border.

Subspecies

Two subspecies are recognized as being valid, including the

Cuora
.

Diet

In Hong Kong, C. trifasciata feeds mainly on fishes, frogs, and carrion, but remains of crabs, snails, and insects have also been found in its feces. It can grow up to a straight-line carapace length of 25 cm (10 in).[6]

Hybridization

C. trifasciata

Asian yellow pond turtle (Mauremys mutica). In addition, the golden coin turtle is suspected to be a parent of two supposed species, the Chinese false-eyed turtle and Philippen's striped turtle.[7]

Conservation

The species C. trifasciata is considered

guīlínggāo (龜苓膏); thus, it is under threat because of unsustainable hunting. It is one of the most endangered turtle species in the world, according to a 2003 assessment by the IUCN.[citation needed] C. trifasciata is listed among Turtle Conservation Coalition's 25 most endangered tortoises and freshwater turtles.[10]

Farming

C. trifasciata is raised on some of China's

Cuora mouhotii, sold for the pet trade, around $80). Taking into account the registered farms that did not respond to the survey, as well as the unregistered producers, the total numbers must be significantly higher.[11] Wild C. trifasciata turtles are far more valuable than farmed-raised turtles of this species to both traditional Chinese medicine practitioners and illegal wildlife traders.[12][13][14] The gender of C. trifasciata is determined by gestation temperatures.[10][14] Due to incubation temperatures at farms in warm lowlands, farms have only been able to produce females.[10][14] This increased the price of wild-caught males to $20,000.[10][14] Most farmed C. trifasciata turtles are hybrids, which can escape and establish populations, causing genetic pollution.[13][14][15][16]

The largest C. trifasciata farming operation is said to be located in Boluo County, Guangdong. According to the farm's founder Li Yi (李艺), the farm was started in 1989 with eight wild turtles (two males and six females) bought at a local market, and now has "over 2000" turtles.[17] According to the farm's site, captive-born turtles start breeding at 8 years of age.[18]
