Etymology
Scientists named the frog knudseni for Jens W. Knudsen, who wrote about biology.[3]
Habitat
This terrestrial frog lives on the ground and in burrows. It has been found in primary and secondary rainforest and savannas. Scientists have seen the frog between 0 and 1800 meters above sea level. Scientists saw the frog in many protected places.[4][3]
Reproduction
Scientists have only seen this frog's tadpoles in primary forest. They have observed the eggs in foam nests and tadpoles in shallow pools of water.[4]
Threats
The IUCN classifies this frog as least concern of extinction because of its large range and moderate adaptability to human disturbance. In some areas, logging may affect tadpoles.[4]
