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.

Comoro Flying Fox

<em>Pteropus livingstonii</em>, the Comoro flying fox or Livingstone's fruit bat, is a large fruit bat in the family Pteropodidae, endemic to the Comoro Islands in the western Indian Ocean, where it is restricted to Anjouan and Mohéli. It is one of the largest bats in the world, with a wingspan that can exceed one meter and a body weight reportedly ranging between 400–700 g. The species roosts colonially in tall native forest trees, particularly in humid upland forest fragments, and feeds on a variety of native fruits, nectar, and pollen, playing a critical role as a seed disperser and pollinator in Comoran forest ecosystems. Precise average lifespan data in the wild remain poorly documented, though captive individuals have lived over 20 years. <em>Pteropus livingstonii</em> is assessed as Critically Endangered by the IUCN, making it one of the most threatened bat species in the world. Primary threats include extensive deforestation driven by agricultural expansion and charcoal production, which has severely reduced suitable roosting and foraging habitat, along with historic hunting. Conservation efforts include habitat protection, community education programs, and captive breeding initiatives at several European zoos coordinated through an international species survival program.
