A Silent Giant
The frog lacks a vocal sac and so does not call. Its tadpoles grow in fast-flowing water, and the adults build nests of stones in the shallows. Its eggs and tadpoles need clean, cool water.
Why Is It Endangered?
Hunting for food, the pet trade, logging that muddies rivers and dam construction have caused declines. Its slow growth and specialized habitat make recovery difficult.
Amphibian Giants
The frog is the heaviest of the frogs, though it is much smaller than the Chinese giant salamander. See Chinese Giant Salamander.
