The Bellona Reefs are a remote group of coral reefs located in the southern Coral Sea, far to the west of New Caledonia's main archipelago. As a key component of the Coral Sea Natural Park, these reefs constitute one of the most pristine marine environments remaining on Earth. Due to their extreme isolation, they support an extraordinarily high fish biomass, characterized by a significant presence of top-level pelagic predators such as reef sharks, tuna, and barracudas. The scattered sand cays and islets within the reef complex serve as indispensable breeding grounds for vast colonies of seabirds, including boobies and frigatebirds. The reefs are of paramount importance to international marine research, providing a baseline for understanding healthy reef dynamics in the absence of direct human pressure. The untouched coral structures and bustling lagoons make Bellona a critical reservoir of biodiversity for the entire South Pacific region.
