Well known for its beautiful fur, the Snow Leopard has a soft grey coat with ringed spots and small dots of black on brown. The fur turns white in the winter. Because their fur command a very high price in the fur market, ring the 1960s, the Snow Leopard's total population went down to 1,000 animals, but has since recovered slightly. The total estimated wild population of the Snow Leopard is between 3,500 and 7,000 indivials (see table below). In addition, there are 600-700 animals in zoos around the
world.

The Javan Rhinoceros （爪哇犀牛） is one of the rarest and most endangered large mammals anywhere in the world. According to 2002 estimates, only about 60 remain alive, in Java, Indonesia and Vietnam. Even these tiny populations are still being poached and the outlook for the species is grim. Of all the rhino species （犀牛物种）, the least is known of the Javan Rhino （爪哇犀牛）, probably e to its low numbers.

The African Wild Dog（非洲野狗）, also known as the African Hunting Dog（非洲猎狗）, is endangered, primarily because of habitat loss and hunting as a result of human expansion along with growing farming and ranching needs. They were once found in 39 nations with an estimated population of500,000 dogs. Now of the 39 countries only 25 remain with an estimated population of 3,000 dogs.

Loggerhead Sea Turtle （蠵海龟，伐木头海龟？）,in temperate and tropical regions of the Atlantic, Pacific, and Indian Oceans,was named for their relatively large heads and powerful jaws. It was once intensively hunted for their meat and eggs, along with their fat which was used in cosmetics and medication. As a result it is now internationally protected through the US, Turkey,Greece, Bonaire and Costa Rica. In the U.S., total estimates for loggerhead nests per year range from 68,000 to 90,000. The worldwide population is unknown, although most populations outside of U.S. waters are declining.

The California Condor（加州秃鹫）is a species of North American bird in the New World vulture family. Currently, this condor inhabits only the western coastal mountains of the United States, Baja California, and the Grand Canyon. Though never great, condor numbers dramatically declined in the 1800's e to poaching, lead poisoning, and habitat destruction. Eventually, a conservation plan was put in place that led to the capture of all the remaining wild condors in 1987 for captive breeding and later reintrocing back to the wild. The project is the most expensive species conservation project ever undertaken in the United States. The California Condor is currently one of the world's rarest bird species. As of 2005, there were only 273 indivials.

The Sea otter (海獭) is a large otter native to the North Pacific. Sea otters have been hunted extensively for their luxurious fur. From 1741 onwards, over-hunting reced sea otter populations to the point of extermination in many parts of their historic range. It is estimated that a half million to a million otters were killed over time. By 1911 the world population was estimated to be just 1,000-2,000 indivials in 13 colonies. Although several subspecies are still endangered, the otters have since been legally protected
