Description Relatively little is known about the distribution of cetaceans in Indian seas due to lack of systematic surveys. For collecting data on species
distribution, 35 opportunistic surveys were conducted onboard FORV Sagar Sampada between October 2003 and February 2007 in the
Indian EEZ and contiguous seas. In 5,254 hours of sighting effort, a total of 473 cetacean records were made with 5,865 individuals. The
occurrence of 10 species from three cetacean families was confirmed. The Indo-Pacific bottlenose dolphin was the most frequently sighted
species, whereas the spinner dolphin was dominant in terms of abundance. Long-beaked common dolphins, Indo-Pacific hump-backed
dolphin and sperm whales were also recorded at frequent intervals. Cetaceans were found to have a wide geographical distribution in the
Indian EEZ and contiguous seas. High abundance and species richness were recorded in the Southeastern Arabian Sea and southern Sri
Lankan waters. From the information collected during the present study, the platform of opportunity has proved to be a useful means for
cetacean survey
