N2  - For years, many studies have been done on the taxonomic classification of swimming crabs but not much on geometric morphometric. Swimming crabs collected belong to Family Portunidae. They are crabs with broad carapace, often with sharp lateral spines. The last pair of legs is flattened at the end, with a paddle like expansion used to swim or to dig in the sand. In this study, portunid crabs collected from Bayug Island, Iligan City and Kawit Occidental, Kauswagan, Lanao del Norte, Philippines were analyzed applying geometric morphometrics (GM) techniques. GM analyses utilized as tools to assess intra-and interspecific right claw and carapace shape and size variation of the three species of Portunidae crabs and, only the right claw and carapace of these crabs- the specific structures understudy since it is known to present allometric trends. Generalized Procrustes superimposition (GLS), thin-palte spline (TPS), partial warp analysis (PW) and relative warp analysis (RW) are the GM applied for landmark analyses; elliptic Fourier analysis (EFA) and eigenshape analysis (EA) for outline shape analyses. Procrustes coordinate values, partial warp and relative warp scores and the elliptic Fourier coefficients derived from different procedure were used for morphometric and multivariate analyses such one-way analysis of variance (ANOVA), Multivariate analysis of variance (MANOVA), Principal Component Analysis (PCA), Discriminant Analysis (DA) and Cluster Analysis (CA). Geometric morphometrics method have become an important tool in identifying shapes and patterns of morphological variations in this study. The results show a relative degree of significant variatons in shapes and sizes of the right claws and carapaces of the three sampled Portunidae species collected (Portunus sp., Scylla serrata and Prtunus sanguinolentus) , showing Scylla serrata right claw shape that are robust and wider compared to the other two groups with claws that are relatively slender and longer while, Portunus sanguinolentus had wider carapace compared to Scylla serrata with carapace shape relatively round and Portunus sp. somewhat ovate. Size and shape variation are more apparent between groups than within groups. Variations have biological implications correlated to regeneration, clade, feeding habits and habitats. Comparisons of shape and size of these three groups using geometric morphometric provide more scientific exploration to evaluate species phylogeny and ontogeny
