However, in modern frogs, almost all muscles have been modified to contribute to the action of jumping, with only a few small muscles remaining to bring the limb back to the starting position and maintain posture. The muscles have also been greatly enlarged, with the main leg muscles accounting for over 17% of the total mass of frogs. [53]
The family Mantellidae is composed of three extremely diverse groups of frogs, across three subfamilies: the Mantellinae (Laurent, 1946) are typically terrestrial or semi-aquatic frogs, the Laliostominae (Vences & Glaw, 2001) are terrestrial, fairly large frogs, and the Boophinae (Vences & Glaw, 2001) are arboreal tree frogs, sharing far more physical and behavioral characteristics with true ...

The frog’s back is chestnut brown with dark brown-black splotches. Underneath, its belly is creamy white with “yolk-yellow” groin and armpits, the study said.
The Sierra Nevada Yellow-legged frogs were almost wiped out of Yosemite National Park. But these scientists mounted a wildlife comeback. 'The lakes are alive again': These frogs are back from near ...
The archaeobatrachians are the most primitive of frogs. These frogs have morphological characteristics which are found mostly in extinct frogs, and are absent in most of the modern frog species. Most of these characteristics are not common between all the families of Archaeobatrachia, or are not absent from all the modern species of frogs.
On Centrolene quindianum, the bluish extension in the arm is the humeral spine. Humeral spines are ventrolateral extensions of the humeral crista ventralis. [citation needed] These structures are present in the humerus of some frogs (). [1]
The Sahara frog is a large species, an exceptional female from Morocco having a snout-to-vent length of 104.5 mm (4.1 in). It is sometimes confused with Perez's frog (Pelophylax perezi), and the published description may be partially of that species. The head is as wide as it is long, the snout is oval and the eyes have horizontal pupils.
