Except for a few wide-ranging seabirds and marine fishes most of Samoa’s biota is strikingly different from that of all other U.S. National Parks. The only native land mammals are three bat species.  For a newcomer from the ‘mainland’ this national park will likely present a bewildering array of paleo-tropical plants, forest birds, reef fishes and corals. Before your visit browse this web site for the park checklists of plants and animals (the corals and marine fishes pages are profusely illustrated).
