用英语介绍动物 同学来猜

The tiger is a mammal of the Felidae family, the largest of four "big cats" in the genus Panthera. Native to much of eastern and southern Asia, the tiger is an apex predator and an obligate carnivore. Reaching up to 4 metres (13 feet) in total length and weighing up to 300 kilograms (660 pounds), tigers are comparable in size to the biggest extinct felids. Aside from their great bulk and power, their most recognizable feature is the pattern of dark vertical stripes that overlays near-white to reddish-orange fur, with lighter underparts.
