The Discovery
In the mountain cloud forests of Ecuador's Intag Valley, researchers mapping local biodiversity uncovered extraordinary wildlife previously thought to be lost. In 2016, scientists from the Jambatu Centre spotted four yellow-splotched toads perched near the Chalguayacu River in the community of Junin. The pocket-sized amphibians were identified as long-nose harlequin toads. The species had been considered extinct since 1989, when a lethal fungal pathogen devastated endemic frog and toad populations across the Ecuadorian Andes.
What Scientists Found
Three years later, biologists working in the same area made another major discovery near a secluded waterfall. They captured a tiny brown frog, small enough to fit inside a matchbox, which initially resembled the rare confusing rocket frog. Detailed laboratory examination revealed that the specimen was an entirely new species.
The newly identified creature displayed ancestral evolutionary characteristics, leading one biologist to describe it as a living fossil or a dinosaur. It was officially named the Intag resistance rocket frog, a nod to the region's long-standing local advocacy against mining developments.
Why It Matters
Ecuador's Intag Valley features unique climate and altitude patterns that harbor remarkable biological diversity. The misty mountain forests shelter spectacled bears, brown-headed spider monkeys, and more than two dozen amphibian species, while acting as a wildlife corridor for the nearby Cotacachi-Cayapas Ecological Reserve.
Biologists and environmental advocates warn that these ancient biological lineages are threatened by proposed open-cut copper mining in the Llurimagua area. Earlier environmental impact assessments showed that mining activities could trigger massive deforestation, forest drying, soil erosion, and water pollution, putting rare species at risk of extinction before their ancient history can be fully understood.
