They often form in biologically isolated areas such as islands and large bodies of water, though humanity has pushed some continent-based animals to an endemic state through hunting and habitat loss. Unfortunately, due to their geographic isolation, endemic species run a higher risk of extinction. 1 of 9 Hawaiian Honeycreeper Sami Sarkis / Getty Images As their name suggests, honeycreepers are endemic to Hawaii. Beautiful song birds with distinctive beaks, honeycreepers specialize in probing flowers for nectar, and have a particular taste for the flower for which they are named. Some subspecies of honeycreepers have developed a beak better suited for catching insects. Just over half the original species of honeycreepers still exist, having been driven to extinction by hunters, disease, habitat loss, competition from invasive species, and predation by human-introduced animals like rats, cats, and dogs. Efforts are underway to protect honeycreepers by eradicating avian flu-carrying mosquitoes, protecting their habitat, and removing invasive species. 2 of 9 Lemurs of Madagascar Tatjana Kabanova / Shutterstock Madagascar, home of the lemur, is one of the global hotspots for endemic species. There are 111 species and subspecies of lemurs. The smallest lemur would easily fit in your hand, while the largest can top 25 pounds. Many lemurs live in matriarchal societies where females call the shots. Most species spend the majority of their time in the trees and travel the forest canopy climbing and leaping — as agile as any monkey. 3 of 9 Formosan Rock Macaque ufoncz / Flickr / CC BY 2.0 Formosan rock macaques are a small (less than two feet in length) species of monkey endemic to the island of Taiwan. They are listed as a protected species because of over-hunting and habitat loss. They are prized for use in medical experiments and have been hunted by locals due to damage to crops. Their numbers fell to an all-time low in the late 1980s, but the population has since rebounded thanks to stronger conservation efforts. 4 of 9 Rhinos of Java ImagineImages / Getty Images Once the most widespread Asian rhinoceroses on the planet, Javan rhinos have been hunted to near extinction. The total number remaining is estimated to be between 58 and 68 individuals, all in Ujung Kulon National Park. The animals are valued for medicinal products and by poachers for their horns. Javan rhinos face an uncertain future of disease and health problems caused by inbreeding. Rhinos don't do well in zoos in general, and the Javans have fared even worse; the last captive died in an Australian zoo in 1907. 5 of 9 Philippine Crocodile Peter Wey / Shutterstock This freshwater crocodile lives only in the Philippines. It is relatively small, as crocodiles go, reaching no more than 10 feet in length. Once hunted for its hide, the Philippine crocodile has had protected status since 2001. Major threats to this critically endangered species are competition with humans for habitat and entanglement in fishing nets. There are only an estimated 100 known Philippine crocs in the wild. 6 of 9 Sinarapan of the Philippines Emerson Sy / Fishbase.se At a maximum length of one inch and rarely longer than half an inch, the sinarapan is the world's smallest commercially harvested fish. The fish are native to the Philippines and are found in only a few freshwater lakes and river systems in that country. They are prized as a food source in Asia. In addition to having to dodge fishermen's nets, sinarapan are under threat from larger invasive species that find them as tasty as humans do. Due to insufficient data, sinarapan are not currently rated by the IUCN. 7 of 9 Santa Cruz Kangaroo Rat John Cancalosi / Getty Images The Santa Cruz kangaroo rat gets its name from its distinctive large hind legs. In the past, this rare animal could be found in the mountains south of San Francisco, but its population has been pushed to a single parcel in the Santa Cruz Sandhills. One of 23 subspecies of kangaroo rat found in California, the Santa Cruz variety is under a real threat of extinction because of dwindling populations and health problems stemming from low genetic diversity. Their loss would be a blow to Santa Cruz mountains — the kangaroo rat is a keystone species that supports many other species; its loss would send a ripple of damage through the entire food web.

Native to the seven islands in the Galápagos archipelago, this long-lived species can live to be 150 years old. Though still threatened after a few centuries of over-hunting, Galápagos tortoises have been making a strong comeback in recent years thanks to the development of the Galápagos National Park and a successful captive breeding program. Unfortunately, the Floreana giant tortoise and the Pinta giant tortoise are functionally extinct. 9 of 9 Haast Tokoeka Kiwi Hal Beral / Getty Images The Haast tokoeka kiwi is a beautiful, unique bird that lives in Haast, New Zealand. This kiwi was classified as a distinct species in 1993. It is considered “threatened nationally critical” in New Zealand with only 400 known remaining. Most Haast tokoeka kiwis live in the Haast Kiwi Sanctuary where predators, like stoats, are controlled — allowing the population to grow.
