27 New Species Discovered in Alto Mayo, Peru

A recent expedition in the Alto Mayo region of north-west Peru has led to the discovery of 27 new species, including a rare amphibious mouse, a tree-climbing salamander, and a unique “blob-headed fish,” The Guardian reported yesterday.

The 38-day survey, conducted by a team of scientists, documented over 2,000 species of wildlife and plants, surprising researchers given the area’s high human population density and environmental pressures.

Among the new mammals identified are a spiny mouse, a short-tailed fruit bat, and a dwarf squirrel. The amphibious mouse, discovered in a threatened swamp forest, is considered one of the rarest rodents. The expedition also recorded seven new fish species, a narrow-mouthed frog, and numerous butterflies and dung beetles.

The findings highlight the region’s biodiversity and the urgent need for conservation efforts. Researchers aim to establish a network of protected areas to safeguard these newly discovered species and their habitats.
