【Science and Technology News】On September 4, the earth has a wealth of biological species, thus ensuring that various animals can coexist, but with the continuous expansion of human life range, the living expenses of more other species have been invaded, resulting in the endangerment of some already rare species, and even some have completely disappeared from the earth.
Let's take a look at the endangered and rare species.
I. The Iberian lynx, also known as the Spanish lynx
The Iberian lynx is also known as the Spanish lynx. It is internationally recognized as the smallest number of medium-sized cats, with fewer than 120 remaining. If people are unable to take effective measures as soon as possible because of various reasons of boredom among human beings, they are likely to become extinct rapidly
The earth has a rich number of biological species, thus ensuring that various animals can coexist, but with the continuous expansion of the human living range, the invasion of more other species of living comfort, resulting in some already rare species on the verge of extinction, and even some have completely disappeared from the earth.
2. Sumatra orangutan
Sumatra orangutan, origin: Indonesia. Despite living in national parks and protected areas, these areas are still so vulnerable to illegal hunting and reclamation by the locals that the number is reduced by 1,000 per year.
3. Australian hairy-nosed wombats
Although not as famous as koalas, this little guy has few companions, no more than 100 in total.
4. Wild Bactrian camels
Wild Bactrian camels are on the brink of extinction, with only about 650 peaks left in the world, so some people call it more precious than the giant panda and have reached a critically endangered state.
Wild bactrian camel is a first-class protected animal in China, inhabiting the Gobi desert at an altitude of 2000 to 2300 meters, semi-desert areas of small mountain basins, often in the same area as yellow sheep and wild donkeys, mainly feeding on desert plants such as red willow and shuttle.
The main reason for the continuous decline in its population is, on the one hand, the changes in the natural environment, which have caused the grassland range where wild Bactrian camels live to shrink; On the other hand, increasing populations and expanding reclamation have robbed wild Bactrian camels of water. In addition, human hunting is also a factor.
5. Deer gazelle
The deer gazelle was listed as an endangered species in 2004 and has fallen by 80% over the past decade to become critically endangered. It lives mainly on the African continent and currently does not exceed 100 heads.
6. Pocket wing bat
The current population of the Pocket-winged Bat is only about 50 to 100, mainly living on the northern shore of the Indian Ocean and on the island of Madagascar.
7. Wild Yangtze crocodile
There are less than 150 wild Yangtze crocodiles in the country, which is also rarer than giant pandas. Yangzi crocodile is China's unique rare wild animals, national first-class protected wild animals, they have a 230 million years of evolutionary history, in more than 70 million years ago basically "stereotyped", and the national treasure giant panda has the same "living fossils" as the name, but the number of wild survivors is far less than the giant panda.
8. Black Rhinoceros
Black rhinos are also known as "African rhinos". Rhino horn is quite widely used, and because of this, it has led to a crisis of extinction.
Nine, two-color marmoset
The bicolor marmoset, also known as the black and white marmoset, is also a highly endangered animal.
10. Leatherback turtle
Leatherback turtles are one of the largest species of turtles in existence. The shell is more than 2 meters long, weighs about 300 kg, and weighs up to 800 kg. Due to over-capture, coupled with the discarding of waste plastic bags in the ocean, the leatherback turtle mistakenly believes that it is a jellyfish and eats it by mistake, resulting in intestinal obstruction and death, so the number is decreasing.
