In ancient times, the Yangtze crocodile was once called the shrew, also has a dragon-like title, called pig po dragon, in the "Liaozhai Zhiyi" there is a special record, indicating that the pig po dragon is produced in Jiangxi, the shape is similar to the dragon, often in the river along the place to hunt geese and ducks, and about it, there are dragons and snakes mated out of the jiao, and then the dragon and the jiao matched to get the pig po dragon, it lives in the same era as the dinosaurs, once also dominated the earth, can be called a living fossil in the biological world, naturally born and brutal, is a crocodile unique to China, It is also one of the smallest crocodile species in the world, although it has experienced hundreds of millions of years of development, the appearance of the Yangtze crocodile has not changed much, but now it is on the verge of extinction, and we need to work together to protect it!
<h1 class="pgc-h-arrow-right" data-track="3" > the smallest crocodile and difficult to breed in captivity</h1>
Yangzi crocodile lives in China's Yangtze River Basin all year round, the body length is only 1-2 meters, the head is flat, the limbs are thick and short, good at useful, the tail is flattened, but it is strong and powerful, if it can quickly help the body move forward in the water, it is also a tool for attacking the enemy and self-defense, the body is short, naturally it is not too heavy, and the adult Yangtze crocodile is only about 36 kg.
They are basically in their own caves during the day, only at night will come out to feed, like a quiet environment, the current human breeding of Yangzi crocodiles, during the day is like to come out to bask in the sun, close their eyes, seem to be asleep, in fact, in the enjoyment of the sun's baptism, giving people a very dull feeling, but in this state is to keep fighting at any time, once they find danger, they will be science to swing their thick tails to escape into the water, or directly attack.
They basically court in May of each year, and mate around June, and the male will build a nest in late June, so that the female can lay eggs around the middle of July, do not look at its small body, the female Yangtze crocodile lays 10-40 eggs each time, basically do not need to hatch, the eggs will hatch in the nest, and the young crocodile will be born in about 60 days, but it will not be long before around November, they will enter the hibernation period.
And when the young crocodile has not yet been born, basically the female Yangzi crocodile to take care of, the market will be guarded near the nest, in order to prevent the invasion of the enemy, until the baby crocodile is born, the female Yangzi crocodile will immediately open the cub's things, help the young crocodile climb out of the nest, guide them into the water, at this time the young crocodile is not very strong, the body surface is still orange-red stripes, and the adult Yangtze crocodile is still different.
As a key protected animal in China, the breeding of the Yangtze crocodile has actually always wanted to be artificial, but the Yangtze crocodile is relatively complex, it is difficult to reproduce under the conditions of artificial breeding, and it has a lot to do with the environment and the feeding environment, and the Yangtze crocodile is still mated in the water, fertilized in the body, and likes to be quiet, artificial breeding is easy to produce some movement, which makes the Yangtze crocodile frightened, naturally less able to reproduce.
As an animal in ancient times, it is a miracle that the Yangtze crocodile has lived for so long, but in the 80s of the last century, it was already on the verge of extinction, which made everyone very worried, fortunately, in time for protection, the current population has grown stronger and stronger.
<h1 class="pgc-h-arrow-right" data-track="17" > gentle by nature and never actively attack</h1>
Everyone's most direct feeling of the crocodile is fierce, but the Yangtze crocodile is gentle in nature, they never take the initiative to attack people, because they have full body scales, when they float in the water, people feel like black wood floating in the water, as long as you do not take the initiative to attack it, the Yangtze crocodile normally disdains us.
When they are floating in the water, they hide their heads and tails in the water, and then the exposed back is actually camouflaged, and when the prey is deceived, they will quickly expose the head and open their mouths to swallow the prey into their mouths.
Yangzi crocodile belongs to carnivorous animals, living in the water, most of them are fed on some fish, on land like some poultry will also become the mouth of the Yangtze crocodile, and as a hibernating animal, their food is quite huge, in the artificial breeding environment, as long as you feed food, they will immediately eat out, in their body has a container that can store nutrient organs, in order to be able to hibernate period, Yangzi crocodile will eat a lot of things before hibernation, and then store nutrients, so in the outside world, It is also very hungry.
As an amphibian, the living environment of the Yangtze crocodile is very huge, in the water can easily catch prey, but on land, it can only be caught with vertical jumping, but its seemingly sharp teeth, in fact, are grooved teeth, can not bite and refuse food, can only clamp food like pincers, on land, they hunt more with a strong tail, so at present, the Yangtze crocodile more hunting place is still in the water.
Looking back, the ancestors of the Yangtze crocodile were actually terrestrial animals, but with the change of the times, let them slowly adapt to life in the water, but their sense of smell and hearing has not changed, it is still very developed, and the long-term ability to dig holes has also continued, resulting in us can see that the caves where they hibernate are dug out by the Yangtze crocodiles using their tails and claws, most of which will be in the bamboo forest on the shore, and some are at the bottom of the swamp of the pond, if you look closely, You'll find that their burrows are quite complex, labyrinthine, and maybe they want a more secure place to live, after all, hibernation takes a while.
<h1 class="pgc-h-arrow-right" data-track="32" > the crises faced by the Yangtze crocodile</h1>
Has lived for hundreds of millions of years of Yangtze crocodile, once faced with the situation on the verge, these are mainly due to the rapid development of human beings, so that the Yangtze crocodile lives in a great danger, because most of them live in the Yangtze River Basin, this place is a human economy developed, the population is relatively dense place, which also let the Yangtze crocodile suffered a lot of harm, not only that, although the Yangtze crocodile has a hibernation period, but still likes in a mild environment, but because the current winter in our country is relatively cold, So many Yangtze crocodiles always fail in the winter!
To this end, the Yangtze crocodile was once located in one of the seven most endangered wild animals in the world, for this reason China attaches great importance to it, began to establish a Yangtze crocodile protection environment, and established a Yangtze crocodile protection base in Xuancheng, Anhui Province, through artificial breeding, so that they can live in a more comfortable place, has slowly got rid of the endangered situation, the number continues to rise.
However, although the number has increased a lot, people through artificial breeding, and then wait until the Yangzi crocodile can adapt to the environment, they began to release, so that although the number can be increased, but the survival rate of the Yangzi crocodile in the wild has not increased much.
However, in order to be able to better protect the Yangtze crocodile, in the current Anhui place has been released 530, at that time in the release, the staff of the reserve has made careful preparations, specially did dna genetic background analysis, select a relatively strong physique, relatively distant Yangtze crocodile for release, and installed a satellite tracker, can better liberate the movement and migration information of the Yangtze crocodile, once the need for help, people will appear around the Yangtze crocodile to help.
And at present this work is still in continuous progress, I believe that under the efforts of people, the survival rate of The Yangtze crocodile will be greatly improved, and as far as possible to reproduce more offspring, as a national level key protection animals, they live in the same era as the dinosaurs, there is too much history, but here still needs everyone to work together to help, although under the guidance of the state, the current life of the Yangtze crocodile has a certain guarantee, but they live in the wild, or need a better ecological environment, We all live on the Blue Planet, and we have an obligation to protect our homeland together, what do you think?
