Chapter 272 (1/2)

After enjoying the crocodile for a while, several people went to the exit and crossed with some oncoming tourists.

Many tourists have finished watching crocodiles on the top and turned back to the bottom!

Generally speaking, the back and forth route is a little stupid. For example, the wolf Pavilion can walk all the visiting points along one road.

However, the path of the crocodile pool is relatively short, so it is more than a few tens of meters. Otherwise, the upper bridge, the underground corridor, and the two sections of slope that gently enter the underground and rise up are too short, which may cause tourists' congestion and make it not beautiful to visit.

At the end of the underground corridor, Da Wu stared at a popular science exhibition board and suddenly patted his thigh: ”ah!”

Lin Hao asked curiously, ”well, what's the matter?”

Dawo pointed to the exhibition board: ”look, the story of crocodile and toothpick bird is false! Been cheated for many years! ”

The exhibition board is equipped with a crocodile with a big mouth and a picture of a bird standing in its mouth. It looks very harmonious.

Lin Hao was also surprised: ”ah?”

Although he had never thought about the crocodile tears before, he knew instinctively that it was false, because what kind of animal would sympathize with tears when hunting to fill his stomach. Isn't it sick? If you catch prey and can live, you should be happy.

But he always thought the story of crocodile and toothpick bird was true. He read it in many story books and chicken soup articles. He also used it in his composition.

”It is said that crocodiles are very fierce. Where crocodiles live, other animals are careful when drinking water by the river for fear of being eaten by crocodiles. However, in nature, there is such a bird that not only does not fear crocodiles, but will take the initiative to get close to them. What is more strange is that crocodiles will not hurt them.

This kind of bird is called toothpick. After eating, the crocodile will open its mouth and let the toothpick bird enter its mouth. The toothpick bird will eat the meat and parasites of the crocodile's teeth and help the crocodile clean. The two are mutually beneficial and symbiotic.

Truth: crocodiles don't need tooth cleaning. Their teeth grow new teeth regularly. Moreover, the teeth of crocodiles are widely spaced, and there is no case of occlusal teeth.

Toothpick birds are generally believed to be Egyptian babblers, but biologists have spent decades observing them and found that they have no habit of picking crocodiles' teeth at all. There are only a few photos of crocodiles and toothpick birds on the Internet, and there is no reliable source.

Many birds are very close to crocodiles when looking for food, and crocodiles don't pay attention to birds when they are in the sun. If the crocodile's mouth is open and there are insects in its mouth, the bird may take a bite. The story of crocodile and toothpick bird may stem from such a misunderstanding. ”

Lin Hao looked at the picture. The crocodile's teeth were very scattered, and his face was the same as constipation!

Nima, with such a wide tooth gap, how can you plug your teeth? It's obviously a rumor! I believed it naively when I was a child.

Dawo sighed: ”now after visiting the zoo several times, we found that we have too many misunderstandings about these animals! Reptiles like crocodiles are also cursed as cold-blooded animals. ”

What animal love is, ”Lin Hao also said,” yes, people like to write fable stories or chicken soup articles with these animals. What is the truth? But can we respect the animal's habits and not make complaints about it, especially this kind of obvious nonsense?

From the crocodile exhibition area, I turned a corner and came to the black boot tortoise exhibition area.

This is a very open place, and some tourists enjoy it at the edge of the exhibition area.

The uneven and slightly undulating ground is covered with a layer of fine fallen leaves. The sun shines on the ground through the gap between palm and banana.

The pool in the middle of the exhibition area is very beautiful, like a clear and bright mirror, reflecting the stones and trees on the bank.

Lin Hao looked at the exhibition area and his eyes brightened: ”Wow, the environment here is very good! What animals do you keep? ”

”Here are black boot tortoises!” Big Wu smiled and stretched out his finger, ”don't you think there's one there?”

The edge of the exhibition area of black boot tortoise is slightly built with stones, and low wood is used as a fence. The protection is very simple. Reaching out and bending down can touch the ground in the exhibition area.

A few meters from the edge of the fence, Xiao Xuan, a black boot tortoise with heavy armor, was slowly moving his scaly legs on the fallen leaves.
