Pristimantis

The description of the new species is based on the examination of eleven adult males and three adult females. The new taxon can be readily distinguished from other congeneric species that inhabit the eastern Andes of Ecuador by the unique combination of the following characters: small body adult males SVL Additionally, we provide information on the advertisement call and natural history of the new species.

However, the environmental and evolutionary factors that drive body size patterns at the interspecific level remain unclear. We found that the models that best explained body size in males, females, and SSD contained environmental variations in temperature, precipitation, and elevation as predictors. In turn, body size has evolved toward an optimum, with a decelerating rate of evolution differentiated between the large Pristimantis clades. Maximilian T.

Pristimantis

According to the team, the new species — named Pristimantis mutabilis mutable rainfrog — changes skin texture in minutes, appearing to mimic the texture it sits on. Skin texture variation in one individual Pristimantis mutabilis ; note how skin texture shifts from highly tubercular to almost smooth; also note the relative size of the tubercles on the eyelid, lower lip, dorsum and limbs. Image credit: Zoological Journal of the Linnean Society. Pristimantis mutabilis , described in the Zoological Journal of the Linnean Society , is believed to be the first amphibian known to have this shape-shifting capability. It belongs to a large genus of approximately frog species found in the southern Caribbean and in Central and South America from Honduras to northern Argentina and southern Brazil. The scientists believe the ability to change skin texture to reflect its surroundings may enable Pristimantis mutabilis to help camouflage itself from birds and other predators. Katherine and Tim Krynak originally spotted the small, spiny frog, nearly the width of a marble, sitting on a moss-covered leaf about a yard off the ground on a misty July night in
