What is the Coral Triangle?
The coral triangle is a unique area recognized worldwide as a center of marine biodiversity, supporting many fish and coral species and ecosystems. Many scuba divers, especially photographers, believe that the Coral Triangle offers the best scuba diving in the world.
Where is the Coral Triangle?
The Coral Triangle is a roughly triangular sea area that includes the tropical waters around Indonesia, Malaysia, the Philippines, Papua New Guinea, the Solomon Islands and East Timor. This huge sea area stretches between the Pacific and Indian Oceans and has two biogeographical regions: the Indonesia-Philippines region and the Far Southwest Pacific region. The Coral Triangle, often referred to as the “Amazon of the Sea,” is almost as large as the lower 48 states of the United States.
The Coral Triangle is a dynamic, lively environment that continues to amaze scientists, divers, and nature lovers. Its richness of marine life creates an ecological wonder that is both interesting to explore and critical to preserve. The Coral Triangle is certainly the gem of our oceans, with its stunning assortment of corals, fish, invertebrates, and symbiotic interactions.
Diving into Biodiversity: Fascinating Marine Life in the Coral Triangle
The Coral Triangle is home to a stunning assortment of marine animals, covering all kinds of life from the smallest crustaceans to the largest fish.
Corals
The Coral Triangle is a living museum of coral diversity, home to over 600 species of reef-building corals, accounting for 76% of all known coral species. These corals serve as the ecosystem’s backbone, providing a habitat for a diverse range of marine species while also preserving the health of the surrounding environment.
Fish
With over 3,000 reef fish species, the Coral Triangle has an unmatched variety of forms, sizes, and colors. Large fish like the whale shark dwell peacefully together with tiny, colorful reef fish. Among these fish and corals are symbiotic relationships, such as cleaner fish that remove parasites from larger species, helping to maintain the ecosystem’s delicate balance.
Invertebrates
Invertebrates are abundant in the Coral Triangle. With approximately 950 mollusk species, 458 crustacean species, and 50% of the world’s razor clam species, the region is a hotspot for invertebrate diversity. Crabs, sea cucumbers, barnacles, and other species live happily in the coral triangle, some in symbiotic relationships with corals and fish.
Turtles and Mangroves
The Coral Triangle is home to six of the world’s seven sea turtle species, as well as the world’s largest mangrove forest. Many coastal species rely on mangroves for nursery grounds, while seagrass beds provide food for endangered turtles.
Symbiotic Relationships
The Coral Triangle’s endless network of life is closely linked by many symbiotic relationships. Anemones and clownfish are classic examples, with the fish benefiting from the anemones’ cleaning and feeding services and the anemones benefiting from the fish’s protection from predators. Other symbiotic relationships are for example the cleaner fish that clean off the parasites of the bigger fish. Also, the dynamic between coral polyps and zooxanthellae (algae) is great example of a symbiotic relationship. Here, the algae produce nutrients for the coral, and the coral provides shelter and carbon dioxide for the algae.
Exploring Top Dive Sites in the Coral Triangle
Let’s explore some of the best dive sites inside the coral triangle, organized by country, and dive into the unique features and highlights of each:
Philippines
