Chinese softshell turtle
Pelodiscus is a genus of turtles in the family Trionychidae, the softshells. Based on genetic and morphological analysis there are six valid species. They are native to Eastern Asia, ranging from the Amur region, south through China and Korea, as far south as Vietnam. Populations in Japan are thought to likely originate from historic human introductions.
Phylogenetic studies have recovered a high diversity of Pelodiscus genotypes in China, some of which may correspond to distinct species. However, the millennia-old practice of farming Pelodiscus for consumption, especially in large-scale farms since the late 20th century, is thought to threaten these lineages due to hybridization with farmed individuals.
Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Pelodiscus.
