–ABSTRACT: This study reports opportunistic sightings of marine mammals between August 2013 and January 2014 in the Andaman region. Seven sightings were recorded during this period out of which one was of a Dugong, which is significant considering its small population size in India and limited data on its distribution and abundance. The rest were 24 dolphins (Tursiops sp.). Four sightings were of the same pod of dolphins on different days at the same location. Two sightings occurred during regular coral reef monitoring survey and the other five during fishery resource survey by trawling operations. These sightings are of great significance as there is a lack of studies on marine mammals from the region. Sighting records are useful for understanding aggregation site, behaviour, habits and habitat and residency patterns and provide important information for conservation of marine mammals.
