Ridge Cochran Frog

Cochranella euhystrix

Unknown

Overview

"Cochranella" euhystrix is a species of frog in the family Centrolenidae. It has an uncertain placement within subfamily Centroleninae. It is endemic to Peru and only known from the vicinity of its type locality near Cerro Blanco, in the Zaña River watershed, Department of Cajamarca. The specific name euhystrix refers to the unusually spiny appearance of this frog, especially males. Common name ridge Cochran frog has been proposed for this frog.

Cochranella euhystrix faces severe threats from habitat destruction due to deforestation and agricultural expansion throughout its limited range in Central American cloud forests. The species' restricted distribution and specialized habitat requirements make it extremely vulnerable to environmental changes and human encroachment. Climate change poses an additional threat by altering the delicate moisture and temperature conditions essential for this glass frog's survival.
