Puntius binotatus is a native fish species in Bayog, Zambaonga del Sur, Philippines. It is locally know as  ”paitan or pait-pait”. Exposure to various environmental conditions, fishes are capable of making adaptations to enable them to survive. One of the manifestations of environmental conditions is their body shape morphology. It is a and indication of what kind of environment that the fishes are living in or the habit that they have. The environment is indeed known as a major force in modelling the morphology of an organism during ontogeny. This study aims to determine the body shape variation within and between the three populations (Depore River, Dipili River and Sibugay River) of Puntius binotatus, using landmark-based geometric morphometrics. A total of 102 specimens were collected and digitized, 34 for each river (Depore, Dipili and Sibugay river) with 17 males and 17 females. Twenty landmark points were used to digitized the specimens where  relative warp scores were derived. PCA, DFA and Thin Plate Spline plot showed that the three populations display sexual dimorphism. Morphology between populations also exhibit significant difference, with Depore and Dipili river spotted barbs having slimmer body and stretched head aspect ratio. These morphological characteristics suggest a more active habit or a habitat with fast water flows.
