National Marine Sanctuary of American Samoa

The National Marine Sanctuary of American Samoa is a marine reserve in the Pacific Ocean protecting coral reefs, deep-sea habitats, and diverse marine life. The area includes several zones with varying levels of protection and is home to numerous coral species and invertebrate animals.

The sanctuary was established in 1986 as Fagatele Bay National Marine Sanctuary, initially protecting a smaller bay area. A major expansion in 2012 added Rose Atoll and other zones to the protected system.

The sanctuary is deeply connected to Samoan culture, where local people practice traditional fishing methods and maintain their relationship with the sea. The community participates actively in conservation decisions and contributes knowledge about sustainable resource use.

The area is accessible by boat, and visitors can explore the coral reefs and marine habitats with local guides or organized tours. The best time for snorkeling and observing marine animals is during warmer months when visibility and water temperature are favorable.

The area is home to Big Momma, one of the largest known coral formations in the world that has developed over thousands of years. This giant coral is significant for marine biology and shows the longevity and growth potential of coral structures.
