Hawai'i is like no other place on earth. Raised above the sea by volcanic action, the islands are home to a fascinating array of animals, most of which are found nowhere else in the world. Because the Hawaiian islands are so isolated-more than 2000 miles from any large land mass-many of its native animals have developed unusual adaptations that help them survive. For example, Hawai'i has whales that sing dolphins that spin through the air bats that turn somersaults as they feed shrimp that climb waterfalls killer caterpillars a tiny blood-sucking bug that survives on the summit of Mauna Kea Hawai'i's habitats are fragile, however, and many of its native species are in danger of becoming extinct. Humans are the most dangerous threats to these threatened animals. Habitat destruction, pollution, development, and introduced species have all contributed to the loss or diminishment of Hawai'i's native species. Hawai'i is the extinction capital of the United States. Only through education and thoughtful conservation can we prevent the disappearance of any more of Hawai'i's unique animals. The first step is to learn about these animals and begin to appreciate their special characteristics.
