Present study of the Amphibian diversity mainly of Anuran amphibian and their habitat preference was conducted for one year between March 2017 to February 2018 at Aurangabad, an important district of Bihar, India. Nine species of Anuran amphibian belonging to four families and eight genera were found to occur in Aurangabad Bihar. The habitat preference of these amphibians are of wide range like in and around the natural and artificial water bodies, human residential area, forested areas, termite nest, tree hole, under spaces of logs, leaf litter and so on. Of the nine Anuran amphibian identified 5 species were found in and around the DeoSuryakund (site-I), all the 9 species were found and identified in and around the area of Raja Jagganath dam Deo (site-II), and 7 species were identified in and around the Umga pond (site-III) of Aurangabad Bihar. Analysis of the collected data on the anuran community of the study area revealed Shannon–Wiener species diversity index minimum (1.213) at site-I and maximum (1.969) at site-II. In contrast Margalef richness index value was minimum (0.693) at site-I and maximum (1.325) at site-II. This study showing he amphibian diversity of Aurangabad and their habitat preference.
