Abstract
AbstractIndividual specimens of Myripristis jacobus Cuvier, 1829 and Scarus taeniopterus Lesson, 1829 were collected from Gopalpur‐on‐sea, Odisha coast, Bay of Bengal. Both the fish samples were assigned species level tags using the conventional taxonomic methods. The capture of both the fish species is of particular interest in that they were new to the Bay of Bengal. Molecular analysis using the mitochondrial cytochrome oxidase subunit I (COI) gene showed high confidence sequence similarity in species identification. The resultant phylogenetic relationships strongly support the monophyly of both the genus with congruent clustering of both the species according to their morphological identification. In addition, the time tree produced is in complete agreement with the recent studies. These studies conclusively prove that both the species might have been originated during the middle to the late Miocene period. Furthermore, both fish species are typical inhabitants of stigmatized coral reefs, confined to the reef regions. These fish species perhaps migrated to the Bengal Bay from the Andaman and Nicobar Islands reef regions because of climatic changes.
