A recent exploration in the Alto Mayo region of Peru has led to the discovery of 27 new species, including an amphibious mouse and various unique fish and insects. These findings highlight the biodiversity of the Amazon rainforest and emphasize the importance of Indigenous communities in conservation efforts.

An expedition in Peru uncovers 27 new species, showcasing the biodiversity of the Amazon rainforest and the role of Indigenous knowledge in conservation efforts.
Amidst the lush landscapes of Peru's Alto Mayo region, a team of scientists has unveiled 27 new species, shedding light on the rich biodiversity of the Amazon rainforest. The expedition, led by Conservation International alongside local Indigenous groups, uncovered remarkable species, including a swimming mouse with webbed feet and an unusual "blob-headed" fish.
The researchers were especially excited about the amphibious mouse, which has partially webbed feet and predates on aquatic insects. This unique rodent belongs to a small group of semi-aquatic creatures that are rare and not often seen by scientists. Meanwhile, the "blob-headed" fish caught their attention due to its notably enlarged head, a feature not recognized before by the scientific community, although local Awajún people knew of its existence.
The expedition also introduced a new species of dwarf squirrel, measuring only 14 cm—half the size of an average British grey squirrel. Conservation International's senior director Trond Larsen praised this discovery, highlighting the squirrel's fast movements and appealing chestnut-brown color. Additionally, the team identified a unique species of spiny mouse, named for its spiky fur, and various new types of fish, amphibians, and butterflies.
Despite the thrill of discovering new species, the findings serve as a reminder of the pressures facing the Alto Mayo region, which is home to a diverse range of ecosystems and Indigenous lands. The area's vulnerable environment is increasingly threatened by human activity, including deforestation and agriculture.
Yulisa Tuwi, an Awajún woman involved in the study, emphasized the importance of this research in preserving their culture and natural resources. She noted that understanding these ecosystems better will empower their community to protect their territory and traditions effectively. Larsens reflected on the wealth of traditional knowledge the Awajún possess regarding their local environment, stating, "They have extensive traditional knowledge about the forests, animals, and plants they live side-by-side with."
The expedition raised the possibility that as many as 48 additional species may also be present in the region, awaiting further studious exploration. The discoveries reflect the outstanding biodiversity of the Amazon rainforest and the pivotal role Indigenous communities play in safeguarding their natural heritage.
