Many of the planet's remarkable creatures are also its most endangered due to unscrupulous poachers and a changing environment. According to the WWF, anywhere from 200 to 100,000 species go extinct every year. Here are 15 animals that may soon be extinct.
1. Javan Rhinoceros: Found in Indonesia and Vietnam, the Javan rhinoceros is perhaps the planet's rarest large mammal. There are currently fewer than 70 of them left.
2. Cross River Gorilla: This beauty is found in Nigeria and Cameroon. Number remaining: fewer than 300.
3. Sumatran Orangutan: Found in Indonesia. The WWF reports that there are approximately 14,000 remaining.
4. Sumatran Tiger: Found in Indonesia, Sumatran tigers are recognizable by the heavy black stripes on their orange coats. Poaching has severely whittled down their population; only about 400 Sumatran tigers exist today.
5. Giant Otter: Found in South America. Giant otters remain endangered as most of their habitats have been destroyed.
6. Black Spider Monkeys: Found in South America. They are endangered by constant hunting and destruction of their tropical rainforest homes.
7. Saiga Antelope: Found in Kazakstan and Russia. With approximately 50,000 left in the world, the Saiga antelope is considered critically endangered.
8. Giant Pangasius Catfish: Found in Southeast Asia. Overfishing has left this species critically endangered.
9. Philippine Eagle: Found on the islands of Luzon, Samar, Levte and Mindanao in the Philippines. This species is critically endangered.
10. Amur Leopard: Found in Southeastern Russia and Northeastern China. Only about 60 are left.
11. Hawksbill Turtle: Found in the tropical waters of the Atlantic, Pacific and Indian oceans. They are often accidentally captured in fishing nets.

13. Yunnan Snub-Nosed Monkey: This rare beauty is found in Southwestern China and is critically endangered.
14. Black-Footed Ferret: Found in North America's Great Plains. Only about 370 are known to exist in the wild.
