Many aquatic species are living in the area; one of them is the Channastriata, commonly known as the snakehead murrel. The results of the study will provide information about the nature of sexual dimorphism in the organism, as well as for making morphological comparisons within and between sexes and individuals. Landmark-based geometric morphometrics were used to describe the shape of snakehead fish Channastriata. Fish were collected, photographed, sexed, and processed in the package software of TPS and undergone landmarking. Hotelling&rsquo;s t-squared applied and p value was calculated Based on the results of Relative Warp analysis, variation in male (RW1 and RW2) and female (RW1 and RW2) occurred mostly in the dorsal region. These variations suggest that there is a highly significant difference in the body shapes of male and female C. striata</span></em><span style=\"line-height: 107%; font-family: \'Times New Roman\',\'serif\'; font-size: 12pt;\" lang=\"EN-US\">(p&lt;&lt;&lt;0.05).</span></p>
