The two poles of the earth have the same species of creatures

Scientists have recently identified that at least 235 species live in the poles of the two poles despite the distance of 8,000 miles (13,000 km) between them.

How can these organisms live on both the top and bottom of our planet? This is still a mystery. The division of habitat as well as distance - for example, warm water between two poles - is one of the problems that can divide organisms that make new species. A DNA analysis study is underway to confirm whether the species that look alike are actually the same.

The researchers also found evidence that cold-water organisms move to the poles to avoid rising seawater temperatures. The research project also brought back photographs of species with wide distribution areas such as ice fleas and a very good anti-cold Antarctic fish that can withstand the temperatures that make fishes another must freeze.

Among the creatures that consider the two seas at the poles are the main ones are long-distance migrants such as gray whales and birds. But the researchers who conducted the project to investigate the number of marine organisms also discovered that the worms live in both polar, crustacean and angelic-like animals.

Ian Poiner, chairman of the project steering committee, said: 'The polar seas are not biological deserts but are in fact full of life in both quantity and diversity'. Biologists from a number of countries have also been studying this issue for two years despite waves of up to 16 meters high and a harsh ice environment.

Poiner said: 'With the cooperation of 500 people from over 25 countries, we have overcome environmental challenges that can discourage anyone from conducting research on scale and importance. ever had. We humans are only at the beginning of understanding the nature of these regions. '

The team estimates that about 7,500 Antarctic creatures and 5,500 creatures live in the Arctic , the total number of globally known marine species is about 250,000. According to scientists, the real number may increase to about 1 million. In general, other scientists say they do not know exactly how many species live on Earth. The National Science Foundation estimates that this number is about 5 million to 100 million species on our planet, but science has only discovered about 2 million species.

Researchers are also gradually learning by what mechanism the polar oceans can act as incubators for adventurous creatures long distances between the two poles when the sea temperature rises or decreased over the years. Last year, they discovered that some octopus species settled in deep waters several times during 30 million years , each time they migrated, coinciding with the melting of Antarctic ice.

Scientists now hypothesize that Antarctica regularly refreshes the oceans of the world with many new species, including a number of different sea spiders and isotopes (this is a species). Crustaceans have relatives with shrimp and crabs. They believe these new species grow as the ice corridors expand around the southern pole. When the ice melts, the creatures radiate to the north and follow the path that the octopus has gone.

Meanwhile, the research project found that smaller marine species are gradually replacing larger species in the Arctic waters. Scientists do not know the exact reason but perhaps it is related to the Arctic food web.
