The Asian finfoot is a rare aquatic bird with lobed toes on its feet. It lives in forest rivers and lakes of Southeast Asia, swims well and dives for prey.
The Asian finfoot differs from related species by its bright black-and-white mask on the head and its preference for dense forest rivers. It is important for nature as a regulator of the number of aquatic insects and small animals.
Immature form that undergoes metamorphosis before adulthood.
