Abstract
This study examines phenotypical variation in skin texture and coloration within individual specimens of Pristimantis cf. kiruhampatu from the Region Amazonas in Peru. We analyzed photographs of the specimens taken at night in the wild under natural, undisturbed conditions and during the day after they were captured. Specimens displayed strong tuberculation at night and smooth skin during disturbed conditions, and the colorations shifted from vibrant green and tan at night to darker hues during the day. Change of skin coloration is known for frogs, but change of skin texture has rarely been observed, and it remains unknown what the advantage of a changing skin texture is. We use photographs of three males, one female, and three juvenile frog specimens to document the observed unusual phenotypical variation.
