Morphometric and phylogenetic analysis of Portunid crabs, Portunus reticulatus (Herbst, 1799) and Portunus pelagicus (Linnaeus, 1758) from the west coast of India

摘要

Present article consists the studies of two species from the Konkan coastal region of Maharashtra for comparative analysis using different morphometric ratios as well as phylogenetic analysis with Cytochrome C Oxidase subunit I (COI) gene. Morphometric ratios were found to be significantly different between P. reticulatus and P. pelagicus. Phylogenetic analysis differentiated P. reticulatus from P. pelagicus producing separate clades in the neighbor joining tree. The study was helpful in corroborating the occurrence of Portunus reticulatus (Herbst, 1799) from the west coast of India.
