Located in the eastern Indian state of Odisha, the Chilika Lake is a vast brackish water lagoon that stretches across an area of 1,100 square kilometers. It is the largest coastal lagoon in India and is home to a rich and diverse ecosystem. Among the many wonders that this enchanting lake holds, one of the most captivating is the presence of the incredibly intelligent and gentle creatures – the dolphins of Chilika.
Chilika Lake is home to two species of dolphins: the Irrawaddy dolphin Orcaella brevirostris and the Indo-Pacific humpback dolphin Sousa plumbea. These dolphins, often referred to as the ‘sentinels of Chilika’, are not only an intrinsic part of the lake’s ecosystem but also the cultural fabric of the surrounding communities.
The Irrawaddy dolphin, named after the river in Myanmar, is a medium-sized dolphin species known for its unique rounded head and short beak. They inhabit the estuarine and coastal waters of Southeast Asia, and Chilika Lake is one of their few remaining habitats. With their distinctive appearance and playful nature, they have become the darlings of both locals and tourists alike.
The Indo-Pacific humpback dolphin, on the other hand, is easily recognizable by its hump-like dorsal fin and the pinkish hue of its body, especially in the mature males. These dolphins are highly social and can often be seen swimming in small groups, showcasing their acrobatic skills by leaping and twirling through the water. Their graceful presence and vibrant coloration make them a spectacular sight for anyone fortunate enough to witness them in their natural habitat.
The dolphins of Chilika play a crucial role in maintaining the ecological balance of the lake. They are top predators, helping to control the population of their prey, which includes various species of fish and crustaceans. Moreover, their movement patterns and feeding habits determine the health of the lake’s ecosystem, offering valuable insights to researchers studying the area.
The Chilika Development Authority, in collaboration with several non-governmental organizations, has been actively involved in monitoring and conserving these magnificent creatures. They conduct regular surveys and research to monitor the population size, distribution, and behavior of these dolphins. Efforts are also being made to mitigate the threats they face, such as fishing net entanglement and habitat degradation due to pollution and human activities.

The local fishing communities have a deep-rooted bond with the dolphins of Chilika. They rely on the lake’s abundant resources for their livelihoods and, over the years, have developed a sustainable fishing practice called “dolphin-friendly fishing.” This traditional method involves communication and coordination with the dolphins, ensuring their safety while still enabling the fishermen to catch fish. This unique relationship between humans and dolphins is a testament to the coexistence of man and nature.
However, despite the conservation efforts, the dolphins of Chilika still face numerous challenges. The construction of illegal prawn gherries (enclosures) and rampant pollution from nearby industries pose a persistent threat to their habitat. Moreover, the lack of awareness among visitors and the absence of strict regulations often lead to disturbance and harassment of these gentle creatures.
It is our collective responsibility to protect and preserve the dolphins of Chilika. Through sustainable tourism practices, stricter regulations, and public awareness campaigns, we can ensure their survival for generations to come. These beautiful creatures are not just a symbol of the lake’s magnificence but also a reminder of the delicate balance of nature that we must strive to maintain.
So, the next time you visit the Chilika Lake, keep your eyes peeled for a glimpse of these enchanting dolphins, and remember to be respectful and responsible in their presence. Let us celebrate their grace and resilience and work together to safeguard their home and our natural heritage.
