Earth’s toughest living being


Tardygrado, this is the name of the most resistant species of planet Earth. This is a translucent micro-animal, has eight legs and measures less than 1mm in length. This was recently considered the most resistant species on our planet.

This being, the tardigrade, is a translucent eight-legged micro-animal, also known as a “water-bear”, was recently considered to be the most resistant species on planet Earth. According to a University of Oxford study, this creature will be able to survive the risk of extinction and still be present on the planet ten billion years from now.

The effects of astrophysical events in the continuation or non-continuation of human life is a serious matter, but little is discussed about the resistance of life itself. A study published in Scientific Reports has explored this. The research also revealed that these tiny creatures are not easy to eliminate. That is, in addition to being able to spend 30 years without any kind of food or water, they are even able to withstand extreme temperatures (-200ºC to 150ºC) and even the space vacuum.

This study, carried out by the University of Oxford in the United Kingdom and Harvard University in the USA, suggests that the tardigrades will live longer after a possible eradication of the human race and also give hope that life Be able to exist in places of sterile and hostile environment, such as the surface of Mars.

“The tardigrades are the closest to the indestructible we have on planet Earth, but it is possible that there are similar species elsewhere in the universe”, explained Rafael Alves Batista, Department of Physics, Oxford University.

This creature can live up to 60 years and grow to 0.5 millimeters and according to the researchers, the only threat posed to this species would be an apocalyptic event that would cause ocean water to boil. The research also explains that there is only a dozen known asteroids and dwarf planets. Where they include Pluto and Vesta, with enough mass to boil the oceans. Still, none of them intersect with terrestrial orbit. Even if the sun exploded in a supernova, that would not be enough to endanger the tardigrades.

In 2016, a team from the National Institute of Polar Research in Japan thawed specimens of this species that had been collected in Antarctica in 1983. Thus, after three inanimate decades, they recovered completely and one day after thawing began to wiggle his paws. In the following days, they moved further until they began to feed.
