sequences with the reference sequences available in portals GenBank (NCBI) and the web-based program DNA Surveillance.

Our molecular investigations allowed us to identify five species of cetaceans from Indian coasts, including Delphinus
capensis, previously reported as D. delphis. We detected unique haplotypes in Indo pacific humpbacked dolphin (Sousa
chinensis; n = 2) and finless porpoise (Neophocaena phocaenoides; n = 12) from Indian coast. On the other hand, some
haplotypes were shared with other regional populations in spinner dolphin (Stenella longirostris; n = 16) and bottlenose
dolphin (Tursiops aduncus; n = 3). Common dolphins (Delphinus capensis; n = 2) had both unique and shared haplotypes
including one highly divergent sequence.},
