The Liangbei toothed toad gets its name from the fact that it has a well-developed set of teeth in its upper jaw. It is a moderately sized species and, since its discovery in 1979, it has only been found to breed in a single stream. It spawns in very slow-flowing water, where the eggs are deposited in clumps (protected from light) under rocks, and hatch into tadpoles that hide between these rocks until metamorphosis. Habitat loss and degradation, due to logging (and an associated reduction in rainfall) and hill fires, represents the major threat to this species. The total population number is thought to be less than 100 individuals.
