Dolphins may have made an appearance along Mumbai’s coastline earlier than usual this year.

As per a report in Hindustan Times, conservation biologist and Malabar Hill resident Darshan Khatau, who has been documenting the movement of the Indian Ocean humpback dolphin annually for the last four years, said sporadic sightings of dolphins were usually seen from the second or third week of December annually up to last week of May (just before the monsoon season).
