Deep inside the mountains of Peru, scientists have discovered two tiny frog species that were completely unknown until now. They were found in a special type of mountain forest called an elfin forest. These forests are cold, wet and often covered in thick mist. They grow high in the mountains, where the trees stay short because of strong winds and low temperatures.The two frogs live more than 3,000 metres above sea level. One has bright red patches hidden on parts of its body, while the other has black patches in the same hidden areas. They are so small and so rarely seen that both were living in the same small part of the forest without anyone knowing they existed. Their discovery shows that scientists are still finding new wildlife in places that have not been fully explored.
What the two new frog species in Peru look like

The study, “Two new sympatric species of Phrynopus (Anura: Strabomantidae) from the elfin forests of Cordillera de Yanachaga in central Peru,” published in the journal PubMed Central, reveals that the frogs belong to a group called Phrynopus, which includes small frogs found only in Peru’s Andes Mountains. Unlike many frogs, they do not go through a tadpole stage. Instead, they hatch from their eggs as tiny frogs that already look like adults.The two new species were discovered in an elfin forest 3,280 metres above sea level in the Cordillera de Yanachaga mountain range, inside Yanachaga-Chemillén National Park in central Peru.The first frog is medium-sized for its group. It has small bumps on its eyelids, heel and lower leg. It also has bright red patches on the inside of its legs and near its groin. These colours are usually hidden and can only be seen when the frog moves or stretches.The second frog looks different. It does not have the bumps seen on the first species. Instead of red, it has bold black patches in the same hidden areas on its body.
Why these frogs’ home is so special
Both frogs live in an elfin forest, one of the rarest types of forests in the world. These forests grow near the tops of mountains, where the weather is cold, windy and wet for most of the year. The trees stay short and twisted, and the ground is covered with moss and small plants.Scientists believe these two frogs live only in the exact place where they were found. They have not been seen anywhere else in the world. This means they have a very small home, making them more at risk if their habitat is damaged.The study also says that areas near the edge of Yanachaga-Chemillén National Park have already been changed by human activities. Even though the frogs were found inside the park, changes outside the park can still affect their habitat. Because of this, the researchers say these mountain forests need strong protection.
