Why is Lakshadweep Known as a Coral Island?

Lakshadweep, a group of islands located off the southwestern coast of India, is renowned for its stunning natural beauty and abundant marine life. One of the key reasons why Lakshadweep is known as a coral island is its unique geographical location and the presence of extensive coral reefs surrounding its shores. In this article, we will explore the factors that contribute to Lakshadweep’s status as a coral island and delve into the significance of coral reefs in this region.

The Geographical Location of Lakshadweep

Lakshadweep is situated in the Arabian Sea, approximately 200 to 440 kilometers off the coast of Kerala, India. It is a Union Territory of India and comprises a total of 36 islands, including 10 inhabited ones. The archipelago stretches over an area of 32 square kilometers and is known for its pristine beaches, crystal-clear waters, and vibrant coral reefs.

The islands of Lakshadweep are located on a submerged bank called the Laccadive-Chagos Ridge, which is a part of the larger Chagos-Laccadive Ridge. This ridge is a prominent feature of the Indian Ocean and extends from the Maldives to the Chagos Archipelago. The presence of this underwater ridge plays a crucial role in the formation and sustenance of coral reefs in Lakshadweep.

The Formation of Coral Reefs

Coral reefs are formed through a complex process involving the growth and accumulation of coral polyps, tiny marine organisms that belong to the phylum Cnidaria. These polyps secrete calcium carbonate, which forms the hard exoskeletons that make up the structure of coral reefs.

The growth of coral reefs is highly dependent on favorable environmental conditions, including warm water temperatures, clear and nutrient-rich waters, and optimal sunlight. These conditions are prevalent in Lakshadweep, making it an ideal habitat for the growth and proliferation of coral reefs.

The Biodiversity of Lakshadweep’s Coral Reefs

Lakshadweep’s coral reefs are home to a diverse range of marine species, making them a hotspot of biodiversity. The reefs support a wide variety of fish, crustaceans, mollusks, and other marine organisms, many of which are endemic to this region.

According to a study conducted by the Zoological Survey of India, the coral reefs of Lakshadweep are inhabited by over 200 species of coral, 600 species of fish, and numerous other invertebrates. This rich biodiversity not only contributes to the ecological balance of the region but also attracts tourists and researchers from around the world.

The Importance of Coral Reefs

Coral reefs are not only visually stunning but also play a crucial role in maintaining the health of marine ecosystems and supporting the livelihoods of coastal communities. Here are some key reasons why coral reefs are important:

  • Biodiversity: Coral reefs are often referred to as the “rainforests of the sea” due to their high levels of biodiversity. They provide a habitat for a wide range of marine species, including commercially important fish and shellfish.
  • Coastal Protection: Coral reefs act as natural barriers that protect coastlines from erosion and storm damage. The complex structure of reefs helps dissipate wave energy, reducing the impact of storms and preventing coastal erosion.
  • Food Security: Many coastal communities rely on coral reefs for their food security and livelihoods. Fishing and tourism related to coral reefs provide income and sustenance for millions of people worldwide.
  • Carbon Sink: Coral reefs play a significant role in carbon sequestration. They absorb and store large amounts of carbon dioxide, helping mitigate the impacts of climate change.
  • Tourism and Recreation: Coral reefs are major attractions for tourists, divers, and snorkelers. They generate revenue through tourism and recreational activities, contributing to the local economy.

Threats to Lakshadweep’s Coral Reefs

Despite their ecological and economic importance, coral reefs around the world, including those in Lakshadweep, are facing numerous threats. Some of the key threats to Lakshadweep’s coral reefs include:

  • Coral Bleaching: Rising sea temperatures due to climate change can cause coral bleaching, a phenomenon where corals expel the symbiotic algae living within their tissues. This leads to the loss of color and eventually the death of the coral.
  • Pollution: Pollution from land-based sources, such as agricultural runoff and sewage discharge, can degrade water quality and harm coral reefs. Excessive nutrients in the water can lead to algal blooms, smothering corals and inhibiting their growth.
  • Overfishing: Unsustainable fishing practices, including dynamite fishing and the use of destructive fishing gear, can damage coral reefs and deplete fish populations.
  • Tourism Pressure: Unregulated tourism and recreational activities can cause physical damage to coral reefs. Activities like anchoring, snorkeling, and diving without proper guidance and regulations can harm fragile coral ecosystems.

Conservation Efforts in Lakshadweep

Recognizing the importance of preserving its coral reefs, the Lakshadweep Administration has taken several measures to protect and conserve these fragile ecosystems. Some of the key conservation efforts include:

  • Marine Protected Areas: The Lakshadweep Administration has established several marine protected areas (MPAs) to safeguard the coral reefs and associated biodiversity. These MPAs restrict certain activities and promote sustainable tourism practices.
  • Community Participation: Local communities in Lakshadweep are actively involved in conservation initiatives. They participate in coral reef monitoring, awareness campaigns, and sustainable fishing practices to ensure the long-term health of the reefs.
  • Research and Monitoring: Scientific research and monitoring programs are conducted to assess the health of coral reefs in Lakshadweep. These studies help identify threats, track changes over time, and inform conservation strategies.
  • Education and Awareness: The Lakshadweep Administration, along with various non-governmental organizations, conducts educational programs and awareness campaigns to highlight the importance of coral reefs and promote responsible tourism practices.


Lakshadweep’s status as a coral island is a result of its unique geographical location, favorable environmental conditions, and the presence of extensive coral reefs. These reefs not only enhance the natural beauty of the region but also support a diverse range of marine species and provide numerous ecological and economic benefits.
