My deep sea fishery

Nowadays, Haidong is very rare, than the giant panda is still scarce, once some people think that Haidong Qing has already been extinct, and even some people directly think that there is no Haidong Qing this creature on the earth, they It is confirmed that Haidongqing is a literary work and a fictitious totem in the film and television drama. It is the same as Dragon, and only exists in imagination.

Untire until ten years ago, when a biological inspection team in Hong Kong in Honghe Nature Reserve in Heilongjiang Province, he found that Haidongqing twice, which fills the gap in Haidong Qing specimen, and people recipients with Haidong. The cyan is currently, my country has made Haidong Yingli to protect animals in the country.

Sit in the firing.

Free of the golden name.

Yellow horse brang card.

These are the embodiment of Haidong's identity value, and it is not enough to show the rare rare of Haidongqing.

If you really want to summarize the precious level of Haidongqing, Xiangyang feels that only this sentence can be summarized.

"This is a living gain, is a living totem."

"Blame." Professor Chen Yu stared at the sea carving of the tiger head in the sky, like what is thinking.

"What's wrong? Teacher, what do you find?" Xiangyang asked.

Professor Chen Yu shook his head, "I found that it is not known that the breeding period of the Hutou seavar is in the alternating season of the spring and summer, the spawning is generally two to three, this season is a bit wrong."

Tiger's seavat does not have Haidongqing so rare, but it is definitely not a common bird.

Tiger's seavar is a standard monk, and it is usually only two eggs.

The color of the egg is white, slightly with green, and the incubation period is forty-five days. The growing speed of the elderly is very slow, and the young birds hatched every year, and its velvet feathers are gray or white.

During the growth period, the velvet feather on the sea carving of the tiger head slowly turned to brown feathers.

A tiger's sea carvant requires a call to give birth to a witch for at least two months. In these two months, the sea carving is very fragile, basically only takes a sea breeze, and a heavy rain will take the small tiger head. Vulture life.

Even if you grow up, the Hou's sea carving is still very fragile. At that time, their skeleton is soft, and there is almost no attack means. They need to leave the eagle nest for about ten months to start learning. Learn the hunting skills.

Moreover, the sea carving of the tiger is not like the Hai Dongqing, three years old, can fight with the fox, five years old, can take the dog.

A tiger's seavar takes four to five years before it can begin to be officially independent.

It takes ten years, Xiaohu head seavar can formally grow the feathers of the bird, at this time, it is officially stepped into the stage of the bird.

There is only 20 years of the life expectancy of a Houcun's sea carving, generally will not exceed 25 years.

Some biologists measuring the survival rate of the small tiger's sea carving to the boy, found that only 30%.

What does that mean?

It means that a pair of Tiger head seavar husband and wife, only two birds have eggs per child, and they have a life in just 20 years, in order to completely pass the major events, they can guarantee that their race is not Extinction, and the sea carvit before the five years old cannot be reproduced,

This is a very fragile race.

"This is not surprising." Fang Friendou is a big cry: "The prosperity is alternating in spring and summer, get married before the ecstasy?

Xiangyang picked his eyebrows, and did not say a word.

In fact, Xiangyang is more preferred to affect the factors of temperature and food affecting the sedation of the sea carving.

The sea carving of the tiger is mainly inhabited in the coast and the river, and sometimes along the river into the inland area far from the sea.

Before the biologists found, several of the tiger-headed sea carvings were all over 3,600 meters above sea level.

The temperature in that place is getting cold.

This ocean fishing boat in Xiangyang has always been in the move, but how is it moving in the Equatorial movement, the equatorial temperature is warm?

As for food?

Xiangyang is not polite, this tiger's sea carving is more than Xieyang yourself.

The temperature is suitable, the food is sufficient, and the tiger's sea cavity will not be very strange.

Not enough, I am still worried. He talked to Chen Yu, talked about his guess, then said: "Teacher, I am actually a bit worried, these two tiger head seafringes have entered the reproductive period in violation of natural conditions. Will there be no bird egg hatching, or the young bird is inadequate? "

Professor Chen Yu carefully thoughtfully, then he was swaying and shaking his head: "No, the reproduction season of animals is not fixed, just like the lion on the prairie, they usually start in the rainy season. The descendants, but some of the lion groups of the water source, they are actually a prosperous future generations, the most important factors affecting animal breeding are sufficient, these two tiger head seavats As long as there is sufficient food, I think they It is possible to reproduce. "

"Even if there is no natural conditions, don't we be there? How many artificial incubation technologies is now?" Professor Chen Yu smiled.

Xiangyang laughed, "Now, this is too early. Although the sea carving of the Tiger Head is a standard of a wife, but they are a very social group, these two tiger head glazes are not going to The reproducibility is not necessarily. "

The Houji seavar is the largest raptor in the Gulf, and it is also the biggest carving class recorded by the world's Guinness record, but they often have a few, more than a dozen gathered together, this habits and sparrows, swallows Some similar.

During the day, the Houji seavat will gather together to hunt together, compete for food, rest together, at night, they will return to their own nest, prohibit other similar entries into their own territory.

"See it." Professor Chen Yu looked up at it.

In half of the air, the huge tiger head of the wings is still underway, and its flight speed is very slow, almost no incited wings, all always in a gliding state.

From time to time, it also Zhang opened the Hawk's mouth, showing deep and hoarse "", sounds like a metal synthetic sound, which is very penetrating, can directly vibrate the eardrum, this is Xiangyang listened The most bright animal outside the whale can make Xiang Yanyuan's madness.

Although the sound of the Huthead seavat is completely different from the rough matte bark of the tiger, but listened, there is a university that is unclear. In short, it is a very very fierce beast. Sound from it.
