From filtering water and providing nourishment to protecting the shores from sediment and storms, the coral reef is the lifeblood of the symbiotic underwater community. The ubiquitous coral reef ecosystem that surrounds the Hawaiian coastlines is a complex structure that supports countless life forms and nourishes Hawaii's interdependent marine community. Accessing these underwater cities also allows divers to see rare and unique indigenous aquatic species found only in Hawaii.

The volcanic activity that formed the Hawaiian Islands continues to expand the island layout with the help of the active volcano Kilauea on the Big Island, constantly adding to the long lava tubes, ornate arches and coral gardens on the sea floor. The topographical layout of the Hawaiian coasts presents an underwater world that draws divers from around the world.

The ancient Hawaiians shared an intimate knowledge of the sea and showed ultimate respect to its inhabitants. The Hawaiian archipelago is not described as islands in a sea, but rather, a sea of islands, thereby acknowledging the ocean as being equally important with the aina, or land. The Hawaiian chant of creation, the kumulipo, explains that all life began in the sea - that humanity is tied to all living things, especially marine life. Malama i ke kai means to 'care for or protect the ocean,' an integral Hawaiian value that dates back over centuries.
