Due to Hawaii's isolation 30% of the fish are endemic (unique to the island chain). [1] The Hawaiian Islands comprise 137 islands and atolls, with a land area of 6,423.4 square miles (16,636.5 km 2). [2] This archipelago and its oceans are physiographically and ethnologically part of the Polynesian subregion of Oceania.
