Australia has been invaded by "rhubarb". Rabbits can be caught above and sharks can be caught below. Why did you become a top crocodile?

Australia, with an area of 7.69 million square kilometers, is located between the South Pacific Ocean and the Indian Ocean, surrounded by the sea. It is the only country in the world that covers the whole continent, so it is also called Australia. Australia has little contact with other continents. Therefore, in the past many years, this continent was isolated from the world, and other continents rarely came to this continent for trade or non-governmental exchanges.

At present, Australia is a diversified immigrant country, but the aborigines in Australia declined sharply because of the colonists from Spain, the Netherlands and other countries in the17th century. Now Australia is a highly developed capitalist country, the most developed country in the southern hemisphere, and the world's 12 largest economy, so Australia's contact with the outside world is getting closer and closer, which also brings a problem to Australia, that is, the invasion of alien species.

Australia's ecological environment is very unique, with many unique animals and plants and unique natural landscapes, but it also leads to a problem that exotic species are easy to flood after coming to Australia. For example, rabbits in Australia are obviously harmless in other countries, and they are also flooded after arriving in Australia, which has become a thorny problem of species flooding.

Australia was invaded by rhubarb and became a top predator.

The alien species I am going to introduce to you today is very different from other alien invasive species in Australia. Generally speaking, all alien invasive species encountered in Australia came from17th century. After Australia was colonized, it was closely connected with the outside world, which led to many species coming to Australia. Such species came to Australia more than 5,000 years ago.

The name of this species is dingo, which is a kind of yellow dog. China tourists will be very surprised if they see this kind of dog in Australia. Isn't this rhubarb, the native dog of China? Why did you become an Australian wild dog? And dingoes are top predators in Australia. It can not only catch rabbits, but also catch sharks in the sea. They live in groups and have almost no rivals in Australia.

Australian wild dogs come from Asia? Now it has become a protected animal.

The wild dogs in Australia are not only very similar in appearance to the native dogs that beat rhubarb in China, but may really be related by blood. In 2005, a research team composed of scientists from Sweden, the United States, New Zealand and Australia conducted genetic tests on wild dogs in Australia and dogs in other parts of the world, and found that the ancestors of wild dogs in Australia arrived in Australia at about the same time as southeast Asian immigrants, so wild dogs in Australia were probably brought to Australia by southeast Asian immigrants, and it did have Asian descent.

Wild dogs in Australia live in tropical forests, grasslands, deserts, plateaus and other natural environments and have strong adaptability. Generally speaking, they catch their prey through teamwork. Although they are the top predators in Australia, they are recognized as pests by human beings and are often killed for bonuses. Therefore, the number of wild dogs in Australia is also decreasing, and it is also included in the Red List of Endangered Species of the World Conservation Union, which is mixed with protected animals. In this respect, you are.
