The Eurasian Otter (Lutra lutra), affectionately known as the “Diya Balla” in Sinhalese and also dubbed the “Ceylon Otter” in Sri Lanka, is an elusive yet enchanting creature. Found primarily in lush riverine habitats and wetlands across the island, these otters are an essential part of Sri Lanka’s diverse ecosystem. They can be spotted in protected areas like the Muthurajawela Wetland Sanctuary and Horton Plains National Park, attracting wildlife photographers and eco-tourists eager to witness their playful antics.
The Ceylon Otters are known for their charming and curious nature, often seen diving and swimming gracefully in search of fish, crustaceans, and frogs. These otters are semi-aquatic mammals, dividing their time between water and land, where they mark territories and rest.
Muthurajawela, with its extensive network of canals, marshes, and mangroves, provides a perfect refuge for these animals. Similarly, the cool, misty environment of Horton Plains supports river systems where these otters thrive, although they remain incredibly shy and difficult to spot in the wild.
The Eurasian Otter is more than just a rare sight; it plays a significant role in Sri Lanka’s eco-tourism industry. Wildlife enthusiasts and photographers from around the world visit places like Muthurajawela and Horton Plains hoping to encounter this playful mammal. Its presence adds depth to the island’s rich biodiversity and highlights the importance of preserving Sri Lanka’s rivers and wetlands.
When these creatures are protected, tourism flourishes—and eco-tourism efforts can directly benefit local communities. Tour guides, wildlife rangers, and conservation groups can leverage this interest to promote sustainable practices and raise awareness about the importance of protecting habitats.
Sadly, despite its value, the Ceylon Otter faces severe threats in Sri Lanka. The species is at risk of local extinction due to:
Industrial waste, agricultural runoff, and untreated sewage contaminate rivers and wetlands, destroying the otter’s habitat and depleting fish populations—their primary food source. Polluted water bodies create harsh conditions, making survival more difficult for these sensitive animals.
Diya Ballas frequently travel between water bodies and cross roads, unknowingly placing themselves in harm’s way. Reckless driving in areas near wildlife habitats has resulted in the tragic deaths of many animals, including otters.
Urban expansion and the conversion of wetlands into farmland or development sites further fragment the habitats essential to otters. As their space shrinks, they face increased competition and stress, leading to population decline.
Efforts are underway to protect Sri Lanka’s otters through awareness campaigns, conservation programs, and eco-tourism initiatives. However, much more work remains to ensure their survival. Here are a few ways we can help:
The Ceylon Otter is more than just an attraction for wildlife lovers—its presence is an indicator of a healthy ecosystem. By protecting this species, we also preserve the delicate balance of Sri Lanka’s rivers and wetlands. The playful charm of the Ceylon Otter should remain a feature of our natural heritage, not a memory of the past.
Let’s work together to safeguard the future of this remarkable creature so that future generations can experience the joy of seeing it.
