Common,Banded Bullfrog

The common banded bullfrog (<em>Kaloula pulchra</em>) is a compact amphibian native to the Indomalayan biogeographic region, where it typically inhabits moist broadleaf forests, coniferous forests, and montane environments. Its geographic range spans several Southeast and East Asian countries, including Brunei, the Philippines, Singapore, and Taiwan. The species is classified as Least Concern on the IUCN Red List, reflecting a relatively stable population across its native range. It is often associated with humid forest floors and edge habitats, where moisture levels support its amphibian physiology. The banded bullfrog is recognizable by its stout body and the distinctive pale lateral stripe that runs along each side. It is known to shelter in soil crevices and leaf litter during dry periods, emerging to feed and breed after rainfall. Breeding typically occurs in temporary pools and flooded areas following monsoon rains, with males producing loud calls to attract mates. Biological traits of this species remain poorly documented in the scientific literature.
