Feb 13, 2025 | Blogs

Did you know coral reefs support over 25% of all marine life, even though they cover less than 1% of the ocean floor? These vibrant ecosystems are crucial for marine biodiversity, providing food and shelter for countless species.

Corals in Andaman are a perfect example of this, boasting one of the most diverse marine ecosystems in India. Beneath the crystal-clear waters, a breathtaking world of coral formations thrives, attracting divers, snorkelers, and marine enthusiasts eager to witness its beauty.

In this blog, we will see why corals in Andaman are important, the best places to see them, the dangers they face, and how people are working to protect them.

Why Corals are Important

Corals are often called the rainforests of the sea. Because they are essential to marine ecosystems as they provide shelter, food, and breeding grounds for numerous marine species.

Contribution to Marine Life

  • Habitat: Coral reefs offer a habitat for over 4,000 fish species and numerous marine organisms.
  • Coastal Protection: The natural coral bridge, such as the Coral Bridge Neil Island, reduces the impact of strong ocean currents on the islands.

Economic Value

  • Tourism: Adventure tourism, including scuba diving and marine adventure, supports the local economy by generating jobs and revenue.
  • Fisheries: Reefs support local fish populations essential for sustainable fishing.

Threats to Corals in Andaman and Nicobar Islands

Despite their ecological and economic value, corals in Andaman face several threats:

Climate Change

  • Rising sea temperatures lead to coral bleaching, weakening reef ecosystems.
  • Increased acidity in oceans impacts coral growth and reproduction.

Human Activities

  • Unregulated tourism: Overcrowding at dive sites damages coral structures.
  • Pollution: Waste disposal and chemical runoff harm marine biodiversity.
  • Fishing practices: Overfishing disrupts the ecological balance of reefs.

Conservation Efforts & Sustainable Tourism

Protecting coral reefs takes effort from governments, conservation groups, and travellers. Here’s what’s being done to keep them safe:

Government Initiatives

  • Marine protected areas like Mahatma Gandhi Marine National Park enforce conservation rules.
  • Regulations on diving and snorkelling help minimize coral damage.

Local Conservation Organizations

  • WWF India supports coral reef conservation through research and awareness programs, focusing on marine biodiversity protection.
  • Reef Watch Marine Conservation engages in coral restoration projects, underwater clean-ups, and educating locals about sustainable marine practices.

How Travelers Can Help

  • Respect marine life: Do not step on corals or disturb their habitat.
  • Reduce plastic waste: Carry reusable bottles and avoid littering.

Best Time to Visit for Coral Exploration

The best time to explore Andaman’s coral reefs is from October to May, but for those looking for a romantic escape, we suggest they plan their trip to Andaman in February. If you’re booking a Havelock Island tour package, this period ensures an unforgettable experience with crystal-clear waters and thriving coral reefs.

Why Avoid Monsoon Months?

  • June to September brings heavy rainfall and rough seas, reducing water clarity.
  • Many diving and snorkelling activities remain closed due to unpredictable weather.
