Earlier this week, as Mumbai came to a grinding halt under a complete lockdown, a series of videos started making the rounds on social media, hailing the ' return' of dolphins to Mumbai's waters. All kinds of theories and locations of their sightings floated around. Some chose to dismiss the videos suggesting that they were fake and doctored like the ones that had emerged from Italy showing dolphins and other marine life returning to Venice's canals as the country was in lockdown.

But, Shaunak Modi, co- founder of Coastal Conservation Foundation and part of Marine Life of Mumbai, gave us some good news when we reached out to him regarding the authenticity of the videos and pictures. Turns out, these dolphins are a common sight in Mumbai's waters, close to Marine Drive. The Indian Ocean humpback dolphins ( Sousa plumbea) have been documented in the area over a long period of time, according to him and his fellow wildlife conservationists who are engaged in studying dolphin activity around city's waters.
