Knudsen's frog, Knudsen's thin-toed frog, or rana dedilarga de Knudsen (Leptodactylus knudseni) is a frog. It lives in Bolivia, Brazil, Colombia, Ecuador, Suriname, Venezuela, Guyana, and French Guiana, and Peru. Scientists think it could also live in Trinidad and Tobago.^[2][3][1]

The adult male frog is about 94.0–170.0 mm long from nose to rear end and the adult female frog is about 102.7–154.0 mm. There is a light-colored line above the mouth. Most of these frogs have some dark triangle-shaped marks. There is a black line from the nose over each eye. There are some marks between the eyes. The belly is light in color. In Peru and Ecuador, the youngest frogs have yellow color on their heads. The iris of the eye is bronze in color.^[3]

Scientists named the frog knudseni for Jens W. Knudsen, who wrote about biology.^[3]

This frog lives on the ground and in holes in the ground. It lives in rainforests that were never cut down and in rainforests that are growing back, grassy places. Scientists have seen the frog between 0 and 1800 meters above sea level. Scientists saw the frog in many protected places.^[1][3]

Scientists have only seen this frog's tadpoles in forests that have never been cut down. They saw the eggs in nests made out of bubbles. They saw the tadpoles in shallow pools of water.^[1]

Scientists from the IUCN say this frog is not in danger of dying out. It lives in a very big place and it is good at living in places that human beings have changed. People cutting down trees for wood might hurt the tadpoles.^[1]
