The Serra da Mocidade mountain range in the northern Brazilian Amazon jungle: researchers are penetrating a wilderness that hardly exists anywhere else on earth. Only the latest satellite technology has made this expedition possible. On their journey into one of the world's most inaccessible mountain regions, Humboldt's heirs discover more than 80 unknown species. A scientific, but also logistical feat, preceded by a 10-year preparation phase. In the Amazon rainforest there is still undiscovered and untouched land, with creatures that no human has ever seen. Serra da Mocidade is a mountain range in the wild north of Brazil. Vast areas of impenetrable jungle make the region extremely difficult to access. Its discovery was only made possible by new satellite technology. After 10 years of preparation, a large interdisciplinary team of researchers embarks on an expedition to the Serra da Mocidade region and discovers over 80 new species.
