"The golden eye beast in the journey to the West should be a hippo!"

"Wow, pigs can fly!"

"Elegance is never out of date!"

"I''ve always wondered why it''s not called a river pig or a hippo! It doesn''t look like a horse at all."

"Think about the seahorse. It doesn''t look like a horse."

"... I was speechless!"

The tourists were talking with great interest.

It''s also a very interesting experience to see such a fat man weighing two or three tons flying around in the water.

A child excitedly shouted to his parents, "Ma Ma! Ma Ma! Take a picture of me!"

While chasing the hippo, he motioned his parents to take a picture with the hippo as the background.

Mother smiled and said, "shoot, shoot!"

The breeder also came to the underwater corridor and explained to the nearby tourists with a headset: "is the hippo a horse living in the river or a pig? In fact, neither! Hippos are actually distant relatives with whales."

Tang Xiaoxin said in surprise, "eh?"

Look at the hippo''s chubby, round figure and short limbs. It''s believable to say that it''s a relative of a pig. It''s too far from a whale! Eight poles can''t hit.

The keeper said with a smile, "isn''t it unexpected? Long ago, hippos and whales had the same ancestors. In the long process of evolution, some of them adapted to life in the sea and became whales, and those more adapted to life on land became hippos.

The most direct similarity between hippos and whales as relatives is that although they can dive, they all have to breathe on the surface of the water, not under the water!

The hippo''s eyes, nose and ears are almost on the top of its head, almost on the same plane. Moreover, its nostrils and ears have a set of flexible muscle tissue that works like a valve.

Usually, hippos will submerge their whole body into the water and only expose their ears, eyes and nostrils out of the water. In this way, they can not only breathe normally, but also find danger in time without being noticed by the enemy.

When a hippopotamus dives into the water, this set of "valves" will automatically close, closing the nostrils and ears, like a waterproof cover, firmly blocking the water, so as to ensure that the nostrils and ears are clean and do not enter a drop of water.

Generally, every three or five minutes, you will float up for a breath. You can dive underwater for half an hour at most!

Moreover, underwater, the closed pores can make ''buzzing'' and ''ticking'' sounds. In this way, hippos can communicate with their companions. The sound can be far away and contain a lot of information, such as location, territory boundary, nearby resources and so on.

This way of communication is also similar to the way whales communicate. "

After listening to the explanation, the tourists around made a burst of exclamation.

"Wow ~"

"Never thought about how they breathe underwater! What a special animal!"

"Diving for half an hour, this lung capacity is also big enough!"

"Hippos and whales are relatives. It really shocked my mother all year!"

The keeper said, "so although hippos always stay in the water, they can only dive and can''t swim!

By pedaling on the bottom of the river and jumping forward, it''s better to walk in the water than to swim. You can pay attention to it. "

Tang Xiaoxin cast her eyes into the water, which would make Pangpang just ready to breathe on the water!

It floated to the bottom of the stone cliff on the bank, stretched out its limbs, fixed its body like a ship anchor, squatted down a little, then gently pushed its front feet, and then pushed its hind legs!

The huge body suddenly flew lightly and floated towards the water.

On the stone cliff, his forelimbs were gently pulled twice, and he came to the shallow water area. Here, he can only vaguely see his ass.

"Oh!!!"

"How awesome!"

Dudu will be quietly motionless, always underwater, lying on a stone, as if he were sleeping.

Tang Xiaoxin looked at it and even envied it!

It should be a comfortable thing to take a bath in cool water in hot summer. It''s really enjoyable.

Pangpang floated to the water for a breath and walked lightly on the stone cliff.

Suddenly one foot stepped empty!

He seemed a little panicked. His head shook on the water and sank slowly. His four short legs swayed violently in the water, and his body twisted around!

"Wow!"

When the tourists saw Pangpang struggling in panic, they also shouted with tension!

But Pangpang twisted his body and adjusted the angle. His body became a posture parallel to the bottom of the water, and he became much more calm at once.

Slowly fall towards the bottom of the water and walk easily.

Seeing this, Tang Xiaoxin breathed a sigh of relief and showed a relaxed smile. "Quack quack" applauded happily: "great!"

Hippo underwater behavior is really interesting and charming!

They watched it with relish for a long time.

……

One day I visited the zoo and was satisfied with it!

Walking to the small farm, I found that there were many children squatting on the grass and gently touching the furry rabbits.

The sheared alpacas walked leisurely in the playground.

After such a long time, brother Aotian has also restored his old temperament. He will stay in the corner, with unruly bangs, and look like thinking deeply about the philosophy of sheep life.

Qian can say hello with a funny smile: "brother Aotian!"

Brother Aotian looked at them and turned his head in disdain.

In the roadside paddy field, the ears of rice have also turned golden, looking heavy and falling.

Tang Xiaoxin looked at the paddy field and looked for the rice he had planted. He said happily, "Wow, it grows so strong! It should be harvested soon!"

Qian Keke looked forward to saying, "I don''t know how it tastes. When I harvest boiled rice, I''ll eat it!"

Before they left, they went to the souvenir shop again!

Seeing the crane themed stationery gift bag placed at the eye-catching position at the door, my eyes immediately straightened.

Before the school students, useful this set of stationery, envy is not good, no student can resist the love of this exquisite stationery!

What''s more, they are still loyal fans of the zoo. One of the goals of coming to the zoo today is to buy a set of stationery.

Quickly one person first brought a gift bag and continued to look like other new souvenirs.

Looking for souvenirs, Tang Xiaoxin felt something at her feet.

Subconsciously looked down, it was a furry Brown Rabbit! He scampered along.

Suddenly he opened his eyes in surprise: "eh?"

The rabbit saw many furry animal puppets on a shelf next to him. He jumped up and pretended not to move.

But the little sister in the breeder''s clothes came over, looked down, reached out and picked it up.

Ruthless iron hand!

It was very clever for the rabbit to be picked up, and there was no resistance, so he was carried away.

When Qian Keke saw this scene, he couldn''t help laughing: "ha ha, prison break failed!"

Tang Xiaoxin thought it was very interesting: "there are no rabbit puppets in the souvenir shop. It''s not seen through at a glance."
