The Snow Leopard (雪豹） is a large cat native to the mountain ranges of central and southern Asia.
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,during 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 individuals (see table below).In addition,there are 600-700 animals in zoos around the
world.
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 reduced 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 individuals in 13 colonies.Although several subspecies are still endangered,the otters have since been legally protected.
