About the Diane's Bare-hearted Glass Frog

Hyalinobatrachium dianae, also known as Diane's bare-hearted glass frog or Kermit frog, is a species of Costa Rican glass frog in the family Centrolenidae. Hyalinobatrachium dianae is lime-green in color with transparent skin on its underside that allows one to view its internal organs. Its skin is uniformly colored without any noticeable light or dark variation. H. dianae has silvery-white irises with small dark spots. The species has bulging white eyes with horizontally-shaped black pupils that resemble those of the Muppet character Kermit the Frog. UPI remarked "Hyalinobatrachium dianae has the kind-hearted muppet's sad but lovable eyes and lanky limbs." H. dianae is roughly 2.5 centimetres (0.98 in) long and lives in rainforest foliage of Costa Rica. It is found at elevations of 400 to 800 metres (1,300 to 2,600 ft) in forest near the Caribbean coast. The known territory of the frog is mostly within protected conservation sites and thus the species is under minimal threat from human activity.

H. dianae is distinguishable from other members of Hyalinobatrachium by its granular skin texture, its uniform color, and its advertisement call. DNA testing confirmed... Wikipedia →
