Chuanbei Toothed Toad

The Chuanbei Toothed Toad (Oreolalax chuanbeiensis) is an Endangered amphibian endemic to the mountains of northern Sichuan Province in southwestern China. It belongs to the family Megophryidae, a diverse group of litter frogs and toad-like amphibians that is particularly species-rich in the eastern Himalayan and southwestern Chinese highlands. The species name chuanbeiensis refers to northern Sichuan (Chuanbei), reflecting its highly restricted geographic range. Like other Oreolalax species, the Chuanbei Toothed Toad is associated with cold, fast-flowing mountain streams, where larvae develop in torrent conditions that require specialized morphological adaptations including oral suckers. Adults are terrestrial outside the breeding season, sheltering in leaf litter and rocky crevices in montane forest. The IUCN has assessed this species as Endangered due to its small known range, ongoing habitat degradation from logging, agriculture, and infrastructure development in mountain areas, and the impacts of chytridiomycosis (amphibian chytrid fungal disease) which threatens Asian megophryid frogs. Limited survey data mean that the species' full extent of occurrence and population size are poorly constrained.

small tortoiseshell

small tortoiseshell (Aglais urticae) is classified as Near Threatened (NT) on the IUCN Red List. Close to qualifying as threatened, with populations that may become vulnerable without conservation action.
