Description :

The snout-to-vent length of the polkadot poison frog is 20 to 22 mm (0.8 to 0.9 in). The hind limbs are short and the forelimbs relatively long with large hands. The fingers are unwebbed, the second one being longer than the first, and all but the first finger have flat discs of thickened skin. This frog has brown eyes and no teeth in its upper jaw. Males have a small vocal sac on the throat, and when not in use, this hangs in folds. The skin on the belly and inside the thighs is coarsely wrinkled. This frog is black or some shade of brown with roundish yellow spots, which often have a raised surface. The call made by the male is similar to that of closely related species but can be distinguished by its pitch, duration and the length of time between successive calls.[3]

Biology :

The polkadot poison frog is arboreal in its habits, living among the mosses and epiphytic plants growing on trees in the dense forests of western Panama at altitudes of up to 1,120 metres (3,670 ft) above sea level. The male typically chooses the leaf of a bromeliad plant on which to call to attract a mate. If receptive, the female joins him in a courtship ritual after which a small batch of
