There are 111 species of amphibians recognized in the country with 95 endemics. Most amphibian species inhabit the rainforests of the wet zone as well as the highland forests and are active at night. Thus observing them, except for the common species, which inhabit the bungalows, is quite a challenge in a national park like Wilpattu where night travel is prohibited.
