As per a report in The Times of India, the water quality in the river Hoogly has significantly improved due to reduced pollution caused by relentless industrial activity and lesser human activities. Wildlife enthusiasts and photographers have allegedly spotted the endangered mammals in areas like Babughat and in city outskirts.

Well, around 30 years ago, it was a normal thing for Gangetic dolphins to be spotted at ghats of Kolkata, but due to increased water pollution, these sightings became almost rare.

The global population of Gangetic dolphins is barely between 1,200 to 1,800.

Well, amid the lockdown these animals are being seen in parts where they were not seen earlier due to human activities. Last month, dolphins were also spotted off Mumbai coast after the lockdown was implemented in India.

Same is the case in Bihar, where Gangetic dolphins have become more visible in the Vikramshila Gangetic Dolphin Sanctuary.
