Chennai is one of the immense habitats of shrimps on the Indian coast and it offers heaps of commercial trading each year. Studies confessed that marine shrimp species have morphologically been delineated. Molecular identification is emerging as an essential vital supportive method for taxonomy-based species identification. In this study, we have provoked molecular data of taxonomically identified marine shrimp from the Chennai coast. All the sequences generated sequences showed 99–100% similarities with the referral database sequences (National Center for Biotechnology Information, GenBank). Sequence analysis of Cytochrome c Oxidase I gene conceivably directed that all the nine shrimp species parted into five distinct groups, which are genetically diverse from each other and exhibited identical phylogenetic reservation to their respective genus. Highest sequence divergence (0.332) have appeared between Heterocarpus gibbosus and Metapenaeopsis mogiensis and the lowest divergence (0.002) between Aristeus alcocki and A. virilis. Intraspecific variation ranged from 0.022 to 0.047 for A. alcocki and Solenocera crassicornis. Interspecific variation extended from 0.003 between M. stridulans and M. barbata to 0.332 between H. gibbosus to M. mogiensis. Thus, pervasive survey and more of molecular data of shrimps might actuate the ambiguous genetic variations and distances between and within the species.
