Pseudhymenochirus merlini is a small aquatic frog from Central Africa. It lives only in water and has sharp claws on its hind legs.
This species differs from related frogs by its very small size and claws on its toes. It helps maintain balance in water bodies by eating small animals and serving as food for fish and birds.
Immature form that undergoes metamorphosis before adulthood.
