Emerald Tree Frog

Zhangixalus prasinatus

Also known as Taipei Green Treefrog, Emerald Foam-nest Frog, Prasinus Green Tree Frog

Emerald tree frogs are vibrant green arboreal amphibians endemic to the humid mountain forests of northern Taiwan. Females deposit their eggs inside airy foam nests whipped together above water-filled tree hollows or artificial pools, allowing tadpoles to drop directly into the water upon hatching. Active mainly on rainy nights, males advertise from bamboo stems and orchard foliage with a distinctive rhythm of rhythmic clicking calls.

Why interaction risk is low: Safe to observe at a normal distance.
What to notice: Look for vibrant emerald skin, pale undersides, and prominent toe pads perched on vegetation near water sources.
Support conservation: Maintain a respectful distance and never touch breeding foam nests or handle the delicate amphibians directly.

Responsible observation

Nighttime Spotting: Search bamboo leaves and low orchard branches using a soft red flashlight on humid evenings.
Listen for Calls: Locate males by following their soft clicking calls near breeding pools after summer rains.
Protect Skin: Avoid handling wild frogs directly to prevent transfer of skin toxins or pathogens.
