On humid, rainy nights, if you hear a low, resonant โwoomโwoomโโ echoing from the ground,
the singer is likely the Asian painted frog.
With its round body, short legs, and burrowing lifestyle, this frog spends most of its life hidden undergroundโemerging suddenly when rain arrives.
Note: In Korea, the name โ๋งน๊ฝ์ดโ often refers to Kaloula borealis. The Asian painted frog usually refers to Kaloula pulchra, a close relative.
