. It lives on the ground and is usually not associated with water. It is typically found at night on ground and in tree stumps, but has also been found under stones and logs during daytime. Presumably, reproduction is by terrestrial larval development. ''Cycloramphus eleutherodactylus'' is a very cryptic species that is difficult to study but might be common. It is locally threatened by
