1, Australian lungfish not only breathes in water with gills like ordinary fish, but also has lungs. Whenever the river dries up in the dry season, it will climb the tree and breathe with its lungs.

2. Giant pandas don't ask for a place to sleep. As long as they are sleepy, they fall asleep anytime and anywhere. Pandas can sleep in different places, from trees to forests. Pandas spend about 10 to 15 hours looking for food every day, and then rest or sleep the rest of the time.

3. The long tail of the bear mouse also has its magical function. When bears and mice jump high, they have to straighten their backs, hind legs and tails to jump. When crossing a tightrope, it also keeps its balance with its tail, just like an acrobat walking a tightrope with a long pole in his hand.

Birds use their tails as flying machines. The bird has long and wide feathers on its tail. When these feathers are unfolded, they can rotate flexibly like fans, and it is easy to master the flight direction. The bird's tail plays the role of rudder in flight, which is called "universal rudder"

Kangaroo's tail is thick and long, full of muscles. It can not only support the kangaroo's body when it is resting, but also help the kangaroo jump faster and farther when it jumps. In an emergency, kangaroos can jump 10 meters or more with their tails.
