Odorrana wuchuanensis

Odorrana wuchuanensis, Wuchuan (odorous) frog, is a species of frog in the family Ranidae that is endemic to Guizhou province, China. It is only known from a single limestone cave in Baicun, Wuchuan; attempts to find it in other locations have failed. Its specialized habitat and extremely confined distribution, combined with increasing pressure from tourism, warrant classifying this species as Critically Endangered.
