The tiger is one of nature’s most perfect predators. With their long teeth,(up to 2.5 inches!) tigers have killed more people than any other mammal. They live in a wide variety of habitats, with temperatures ranging from -30 to 118 degrees F. In spite of their adaptable nature and skillful hunting, tigers are nearly extinct. Three of the eight varieties of tigers are completely extinct, with the other five precariously hanging on. Humans have hunted tigers for centuries and are now destroying their habitats.
