Being mammals ourselves, we tend to feel most passionately for the plight of other mammals, such as tigers and pandas. Most endangered mammal species are threatened by habitat loss while a significant percentage continue to be hunted despite dwindling population sizes.

According to the IUCN, some 20 percent of all known mammal species are either threatened or endangered. That's nearly 1,100 species. Some, like the baiji, are likely beyond hope. Others, like the giant panda, continue to make strides in the right direction.
