Abstract
Flat fishes are known for their uniqueness by possessing both eyes on one side of their body, either sinistral or dextral, and are an essential component of the food chain and food web. The present study reports the geometric morphometric (GM) analysis of five species of the family Bothidae, four species of the family Cynoglossidae, and four species of the family Soleidae collected from Gopalpur-on-Sea, Odisha coast to understand their shape variation. The GM analysis supplements the morpho-taxonomy to discriminate population, evident from the principal component analysis, canonical variates analysis, and discriminant function analysis. Landmarks-based GM can elaborate shape differences between species and provide a meaningful way to improve the visualization and quantification of these differences at the time of species identification.
