Hawaiian fauna is unique due to the islands' isolation, leading to a high number of endemic species. This includes birds like the Hawaiian honeycreeper, which has evolved into various forms, and the nene, or Hawaiian goose, which is the state bird. The islands also host diverse marine life, including the Hawaiian monk seal and various species of colorful fish. In addition to birds and marine animals, Hawaii is home to unique insects and land mammals. The Hawaiian happy-face spider is a notable endemic species, while the islands lack native terrestrial mammals, leading to a reliance on introduced species. Conservation efforts are crucial to protect this fragile ecosystem.
