Giant panda
The giant panda is universally loved, and has a special significance for WWF as it has been the organization’s symbol since it was formed in 1961.

The unique physical features of the species include broad, flat molars and an enlarged wrist bone that functions as an opposable thumb – both of these adaptations are used for holding, crushing and eating bamboo. Giant pandas are classified as bears and have the digestive system of a carnivore, but they have adapted to a vegetarian diet and depend almost exclusively on bamboo as a food source.

Today, the giant panda’s future remains uncertain. This peaceful, bamboo-eating member of the bear family faces a number of threats. Its forest habitat, in the mountainous areas of southwest China, is fragmented and giant panda populations are small and isolated from each other. Meanwhile, poaching remains an ever-present threat.

Yangtze river dolphin
The Critically Endangered Yangtze river dolphin, or baiji, is one of seven freshwater dolphin species. It once lived in the lower and middle reaches of the Yangtze River, Fuchun River, and in Dongting and Poyang Lakes, China. Today it is the world’s most endangered cetacean. Fewer than 100 were thought to survive in the middle reaches of the Yangtze, however a 2006 survey failed to sight any individuals, raising fears that the species is one step closer to extinction.
