Chilika, a native buffalo breed of the Eastern coast India, is mainly distributed around Chilika brackish water lake connected with Bay Bengal Sea. This possesses unique ability to delve deep into salty and stay there feed on local vegetation saline nature. Adaptation salinity genetic phenomenon; however, basis underlying tolerance still limited in animals, specifically livestock. The present study explores evolution that unveils buffalo's adaptation harsh habitat, including both food systems. For this study, whole genome resequencing data 18 for comparison 10 Murrah normal habitat were generated. identification selection sweeps, intrapopulation interpopulation statistics used. A total 709, 309, 468, 354 genes detected possess sweeps using nucleotide diversity (θπ), Tajima's D, ratio (θπ-ratio), F
