Microhyla petrigena

Small amphibian species endemic to Khao Sok National Park in Surat Thani, Thailand. This rare and ecologically significant species is found only in this specific region.

The Khao Sok Dwarf Frog is very small, with an average length of about 1.5-2 centimeters. It has a stout, short body with a light brown or gray base color, often adorned with dark spots or lines that help with camouflage. This species typically inhabits areas with high humidity, such as rainforests or near small water bodies, and it prefers to hide under fallen leaves or in soil crevices.

Its primary diet consists of small insects and other invertebrates, and it is nocturnal, coming out to feed during the night when humidity is higher and temperatures are lower.


Due to its limited distribution and sensitivity to environmental changes, conserving its habitat is crucial. Visitors to Khao Sok National Park may have the chance to encounter this dwarf frog while hiking or exploring nature, particularly in damp, shaded areas.


The Khao Sok Dwarf Frog is a remarkable example of the park's rich biodiversity and serves as a reminder of the importance of conserving this fragile ecosystem.
