***Sri Lanka Humpback Whale - Megaptera novaeangliae***
Short:
Migratory ocean giant seen off Sri Lanka’s coasts; threatened by ship strikes, entanglement, and ocean changes.
Facts:
Habitat: Coastal and offshore waters around Sri Lanka, especially deep sea migratory routes.
Threats: Ship strikes, entanglement in fishing gear, climate change, noise pollution, and plastic pollution.

Details:
The Humpback Whale is one of the most iconic and majestic marine mammals found in the Indian Ocean. Although not resident to Sri Lanka like the Blue Whale, humpbacks are seasonal migratory visitors, passing near Sri Lankan waters during their long ocean journeys between feeding grounds in polar regions and breeding grounds in tropical waters.
Humpback Whales are known for their:
Spectacular breaching and tail-slapping displays
Long, complex songs, often lasting 10-20 minutes and repeated for hours
Distinctive body shape with long pectoral fins and knobbly head tubercles
Adults can reach up to 14-17 meters in length and weigh 30-35 tons. They primarily feed on krill and schooling fish, using remarkable bubble-net feeding techniques to herd prey.
Sri Lanka's position along major Indian Ocean migratory routes makes the island an increasingly important region for humpback whale observations.

Major Threats:
Threat Explanation
Ship Strikes Heavy shipping lanes around Sri Lanka overlap with whale migration routes, causing fatal collisions.
Fishing Gear Entanglement Nets, long lines, and ropes can trap whales, causing injury or drowning.
Climate Change Alters ocean temperature and prey distribution, disrupting migration and feeding patterns.
Noise Pollution Loud engines and sonar interfere with whale communication and navigation.
Plastic & Marine Pollution Ingestion of plastics and toxins poses growing health risks.
---
Conservation Notes:
Protecting Humpback Whales in Sri Lanka requires:
Monitoring migratory routes and adjusting major shipping lanes when possible
Promoting safe, responsible whale-watching guidelines
Reducing ocean noise and marine pollution
Strengthening protection under international marine conservation agreements
Sri Lanka’s oceans have the potential to become one of the most significant marine mammal conservation zones in the Indian Ocean if properly safeguarded.
