About Agalychnis spurrelli Boulenger, 1913
Agalychnis spurrelli, commonly called the gliding tree frog, has distinct size differences between sexes: males reach a snout-to-vent length of 48 to 56 mm (1.9 to 2.2 in), while females measure 60 to 72 mm (2.4 to 2.8 in). This species has a broad head and large eyes with reticulated lower eyelids. It has a slim body; the skin on its dorsal surface and limbs is smooth, while the belly has granular skin. Its limbs are slim, and both the fingers and toes bear adhesive discs. Fingers are around three-quarters webbed, and toes are fully webbed. The dorsal surface changes colour from pale green to dark green at nightfall, and the underparts are cream and orange. The gliding tree frog is native to humid forests in south-eastern and south-western Costa Rica, Panama, the Pacific lowlands of Colombia, and north-western Ecuador.
