Conservation of habitats and flagship species, such as the Asian small-clawed otter, is one of the most effective ways to conserve aquatic biodiversity. The study was conducted at Karlapat wildlife sanctuary, Odisha, India, and aims to determine the habitat and diet preferences of Asian small-clawed otters. Presence-absence of Asian small-clawed otters and associated habitat variables were recorded along 1-km sections of streams and rivers. We used principal component analysis (PCA) and logistic regression to examine habitat variables influencing otter presence along streams and rivers. Diet analysis of Asian small-clawed otters was conducted to calculate the percent frequency of occurrence and score-bulk estimate of each food item in the study area. We found that the presence of Asian small-clawed otters was related to denser canopy, higher shrub cover, and rocky stretches. A logistic regression model showed that Asian small-clawed otters significantly selected for higher canopy cover. Crabs were found to be the most preferred food item (&gt;80%) in the diet of Asian small-clawed otters. These findings shed light on the regional-scale habitat selection and diet of Asian small-clawed otters and indicate important species-habitat relationships, thus providing valuable information for conservation management and land-use planning.
