Chinese softshell turtle
The Chinese softshell turtle (Pelodiscus sinensis) is a species of softshell turtle that is native to mainland China (Inner Mongolia to Guangxi, including Hong Kong) and Taiwan, with records of escapees—some of which have established introduced populations—in a wide range of other Asian countries, as well as Spain, Brazil and Hawaii.
Populations native to Northeast China, Russia, Korea and Japan were formerly included in this species, but are now regarded as separate as the northern Chinese softshell turtle (P. maackii). Furthermore, localized populations in Guangxi and Hunan (where the Chinese softshell turtle also is present), as well as Vietnam, are recognized as the lesser Chinese softshell turtle (P. parviformis) and Hunan softshell turtle (P. axenaria).
The Chinese softshell turtle is a vulnerable species, threatened by disease, habitat loss, and collection for food such as turtle soup. Additionally, millions are now farmed, especially in China, to support the food industry, and it is the world's most economically important turtle.
Females of the Chinese softshell turtle can reach a straight-line carapace length of up to 33 cm (13 in) while the smaller males reach 27 cm (11 in), with longer tails than the females. Sexual maturity is reached at a carapace length of 18–19 cm (7.1–7.5 in).
It has webbed feet for swimming. It is called "softshell" because its carapace lacks horny scutes (scales). The carapace is leathery and pliable, particularly at the sides. The central part of the carapace has a layer of solid bone beneath it, as in other turtles, but this is absent at the outer edges. The light and flexible shell of this turtle allows it to move more easily in open water, or in muddy lake bottoms.
The carapace of P. sinensis is olive in color and may have dark blotches. The plastron is orange-red, and may also have large dark blotches. The limbs and head are olive dorsally with the forelimbs lighter and the hind-limbs orange-red ventrally. There are dark flecks on the head and dark lines that radiate from the eyes. The throat is mottled and there may be small, dark bars on the lips. A pair of dark blotches is found in front of the tail as well as a black band on the posterior side of each thigh.
The Chinese softshell turtle is native to Taiwan and China, where it is found in Anhui, Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hebei, Henan, Hong Kong, Hubei, Hunan, Inner Mongolia (Nei Mongol), Jiangsu, Jiangxi, Shaanxi, Shandong, Shanxi, Sichuan, Yunnan and Zhejiang Provinces.
Populations native to Northeast China, Russia, Korea and Japan were formerly included in this species, but are now regarded as separate as the Amur softshell turtle (P. maackii). Populations in Vietnam and Hainan Island are now recognized as the spotted softshell turtle (P. variegatus). Furthermore, localized populations in Guangxi, Hunan, and Anhui (where the Chinese softshell turtle also is present) are recognized as the lesser Chinese softshell turtle (P. parviformis), Hunan softshell turtle (P. axenaria), and Huangshan softshell turtle (P. huangshanensis).
