In a significant scientific breakthrough, researchers from Conservation International alongside indigenous communities have identified 27 new species in Peru, including an extraordinary amphibious mouse with webbed feet, while potentially uncovering up to 48 additional species pending further study.

New Mouse Species and 27 Other Discoveries Uncovered in Peru
Scientists reveal exciting new findings, including an amphibious mouse and unique fish, during a recent expedition.
Amidst the diverse ecosystems of the Alto Mayo region, which includes parts of the Amazon rainforest and is populated by indigenous groups, the expedition highlights the profound impact of local knowledge on biodiversity conservation. Trond Larsen, Conservation International’s senior director, expressed astonishment at the diversity discovered despite the human pressures like deforestation and agriculture surrounding the area.
The Awajún people, integral to the research, shared their extensive traditional knowledge about the local flora and fauna, underscoring their connection to the land. Among the exciting finds were not just the amphibious mouse but also a new species of dwarf squirrel, eight types of fish, three amphibians, and 10 butterflies.
The newly identified "blob-headed" fish shocked scientists with its distinctively enlarged head, even though local populations were already familiar with it. The new dwarf squirrel species, measuring just 14 cm (5.5 inches), is remarkably smaller than the average grey squirrel. Its playful and agile nature reflects its adaptation to the trees of the region.
Moreover, a new spiny mouse species was identified, characterized by its unique spines functioning like those of hedgehogs. Among the remarkable discoveries was also a tiny arboreal opossum and an array of butterflies, showcasing the vast biological wealth of this region. The findings not only deepen scientific understanding but also empower the indigenous communities to further protect their cultures and resources in the face of growing environmental challenges.
