Top 6 Marine Species You Can Encounter While Diving in Maratua

Few places in the world can rival the untouched beauty of Maratua Island. Nestled in the Derawan Archipelago, East Kalimantan, this small crescent-shaped island has earned a global reputation as one of Indonesia’s best diving destinations. The crystal-clear waters, healthy coral reefs, and thriving marine biodiversity make every dive here unforgettable.

If you’re planning a diving trip to Indonesia, here are six extraordinary marine species that will make your Maratua adventure truly special.

The Rich Marine Biodiversity of Maratua

Maratua lies at the heart of the Coral Triangle, often called the “Amazon of the Ocean,” home to 76% of the world’s coral species. This nutrient-rich ecosystem supports an astonishing variety of marine life—from tiny nudibranchs to massive whale sharks. The surrounding areas like Kakaban Island and Sangalaki are also world-renowned dive sites that attract both professional divers and marine researchers. Each dive promises new surprises, revealing the vibrant balance between reef life and pelagic species that define this underwater paradise.

6. Parrotfish & Napoleon Wrasse

Amid the coral gardens, you’ll find brightly colored parrotfish and the majestic Napoleon wrasse, two key species vital to coral reef health. Parrotfish clean the reefs by feeding on algae, while the large, blue-green Napoleon wrasse adds a rare and royal touch to the underwater scene. Sadly, both species face threats from overfishing, so witnessing them in Maratua is a precious reminder of why marine conservation matters.

Responsible Diving, Protecting Maratua’s Marine Heritage

Diving in Maratua means becoming part of its conservation story. Always follow eco-diving practices: avoid touching corals, control your buoyancy, and never feed marine animals. Local dive operators and resorts, including Sienna Resort Maratua, work closely with conservation groups to preserve the area’s marine ecosystem. By diving responsibly, you help ensure Maratua’s underwater paradise remains vibrant for generations to come.

Plan Your Dive Trip to Maratua

The best time to dive in Maratua is between March and October, when visibility reaches up to 30 meters and marine life is most active. Access is typically via Berau or Tarakan, followed by a scenic boat ride to the island.
