Yellow-margined Box Turtle

Yellow-margined Box Turtle | The Chinese box turtle is a species of Asian box turtle with several names. Its common names include Chinese box turtle, 食蛇龜 Snake-eating turtle, Yellow-margined box turtle, and Golden-headed turtle. Taxonomically, it has been called Cistoclemmys flavomarginata, Cuora flavomarginata, and Cyclemys flavomarginata. The Integrated Taxonomic Information System uses Cuora flavomarginata.

Yellow-margined Box Turtle has a highly domed shell, the carapace and plastron of which are a dark brown, excepting 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 in color while the top of the head is a 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 pink-ish 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 Yellow-margined Box Turtle is slight. Males have a broader tail than females; it is almost triangular in shape.
