Darwin's frog is a tiny, special amphibian from South America.

It lives in the Valdivian Temperate Rain Forest. This forest covers parts of Chile and Argentina. These frogs like wet places like bogs and slow streams. They often stay in mossy areas or under old wood. Short plants help keep the soil cool and wet for them. This also helps them hide from animals that might eat them.

This frog has a very unusual way of being a dad. A female lays eggs, often in leaf litter. After a few weeks, the male swallows the eggs. He holds them inside his vocal sac, which is the throat part used for calling. The eggs hatch into tadpoles inside his throat. These tadpoles stay there for about six weeks. They eat from the sac while they grow. Finally, tiny new frogs hop right out of the father's mouth.

Scientists have studied this frog for a long time. Charles Darwin saw them during his voyage on the HMS Beagle. He visited Chile and found these amazing creatures. Later, in 1841, two experts named them. André Marie Constant Duméril and Gabriel Bibron gave them their scientific name. These men helped the world understand this unique species. Their work started the long history of studying Darwin's frog.

Many interesting facts exist about how these frogs look and act. Males can change color from brown to green in captivity. This change likely happens to match their green environment. Most brooding males are green to hide in plants. Females are usually brown to match the ground.

The frogs eat small bugs like spiders and beetles. They use a "sit and wait" style to hunt. This helps them save energy while they look for food.

Today, Darwin's frog faces many hard jobs to stay alive. They are listed as an endangered species. This is because their forest homes are being turned into tree farms. Wildfires and a fungal sickness also make life difficult. Their habitat has decreased by up to 40% between 1970 and 2010. Many people are working hard to help them. Zoos in Chile have started special groups to keep them safe.
