Giant pandas, rhinoceros, mountain gorillas, and tigers are endangered species. Giant pandas only have 1,600 left in the wild and have lost their habitat in China. Rhinoceros can weigh up to 8,000 pounds but are hunted for their horns, and mountain gorillas have dwindled to fewer than 650 due to forest destruction. Tigers are the largest cat but several subspecies are already extinct, and the remaining populations of other types such as South Chinese and Siberian tigers number only in the few dozens.
