Chong'an Moustache Toad

The Chongan Moustache Toad (Leptobrachium liui) is a robust, terrestrial frog in the family Megophryidae, native to the subtropical mountainous forests of south-central China, particularly the western Fujian, Jiangxi, and Sichuan provinces. Megophryid frogs are a diverse Asian family adapted to cool, humid forest streams, and many species display remarkable breeding biology. The moustache toad is best known for the extraordinary breeding biology of its congener Leptobrachium boringii — males of that species grow sharp, keratinous spines on the upper lip during the breeding season, used in aggressive fights over calling sites — and similar adaptations may occur in L. liui. Adults are cryptically coloured in browns and greys, resembling leaf litter. They breed in fast-flowing mountain streams, where females deposit large eggs in sheltered sites and the resulting robust, bottom-grazing tadpoles are well adapted to current environments. The IUCN classifies Leptobrachium liui as Least Concern with a broad enough range in montane forest habitats of central China to sustain viable populations. Threats include forest degradation, water pollution from agricultural runoff, and collection for the food and traditional medicine trades, which affect many frog species in China and Southeast Asia.
