High in thick bamboo forests in the misty, (rain) mountains of southwestern China (live) one of the world's rarest mammals: the giant panda, also called the panda, Only about 1,000 of these black-and-white (relative) of bears survive in the wild.
Pandas eat almost nothing bamboo shoots and leaves. (occasion) they eat other plants, fish, or small animals, but bamboo accounts for 99% of their diets.
Pandas eat fast; they eat lot, and they spend about 12 hours a day (do) it. The reason is they digest only about a fifth of what they eat. Overall, bamboo is not very nutritious. To stay healthy, they have to eat a lot-up to 15 percent of their body weight in 12 hours-so they eat fast.
Pandas' molars(臼齿) are very broad and flat. The shape of these teeth helps the animals crush the bamboo shoots, leaves, and stems they eat to get the bamboo to their mouths, hold the stems with their front claws, which have enlarged wrist bones that act as thumbs for grasping things. A panda should have at least two bamboo species where it lives, or it will starve. Pandas are shy; they don't go into areas people live. This restricts pandas to very limited areas.
