Even tardigrades, the most indestructible animals in the world, will not survive global warming

Even “the most indestructible animals in the world” cannot survive global warming because experts believe that the Achilles heel of Tardigrade is prolonged exposure to high temperatures.

  • Tardigrades can survive some of the toughest environments on Earth
  • A new study discovered that their weakness is prolonged exposure to high temperatures
  • Tests have shown that they have a 50% chance of surviving temperatures above 98.78F
  • Experts are now wondering how these creatures will survive global warming

Researchers have discovered the most indestructible animal on earth of the Achilles heel: global warming.

Tardigrades can survive the vacuum in the room, frozen or exposed to radiation, but are unable to tolerate prolonged exposure to high temperatures.

A study showed that specimens that were not used to heat had a death rate of 50 percent from surviving temperatures above 98.78 degrees Fahrenheit over a 24-hour period.

The specimens were collected in Denmark, where officials warn that they will suffer from warmer summers and longer heat waves due to climate change, causing experts to question the fate of these creatures in a warmer world.

Researchers have discovered the most indestructible animal on earth of the Achilles heel: global warming. Tardigrades can survive the vacuum in the room, frozen or exposed to radiation, but are unable to tolerate prolonged exposure to high temperatures.

“The global warming is already having harmful effects on habitats worldwide and it is therefore important to understand how rising temperatures can affect existing animals,” wrote the researchers at the University of Copenhagen in Denmark in the study published in Scientific Report.

“Here we investigate the high temperature tolerance of Ramazzottius varieornatus, a tardigrade that is often found in transient freshwater habitats.”

“Using logistic modeling for activity, we evaluate the effect of 24-hour temperature exposure on active tardigrades, with or without a short acclimatization period, compared to exposures of dried-out tardigrades.”

The team collected a sediment sample from a gutter in Denmark with adult tardigrades.

Postdoc Ricardo Neves, who I involved in the study, said: “The specimens used in this study were obtained from gutters of a house in Nivå, Denmark.”

“We evaluated the effect of high temperature exposure in active and dried tardigrades, and we also examined the effect of a short acclimatization period on active animals.”

They discovered that about 50 percent of tardigrades died in the active state when the temperature was raised to 98.78 degrees Fahrenheit.

If they had the time to acclimatize, they reached 99.68 degrees.

However, the team observed samples in a cryptobiosis state, as they adapt to environmental stress, they could survive temperatures of up to 108.86 degrees for one hour.

And if it was exposed for 24 hours, the maximum temperature was 145.58 degrees Fahrenheit.

According to Climate Change Adaptation, a website of the Denmark Ministry of Environment and Food of Denmark and the Environmental Protection Agency, climate change will lead to warmer summers, longer heat waves and more drought.

“The fact that the median lethal temperature for active R. varieornatus is so close to the median maximum temperature in Denmark – where the samples used in this study were sampled – is, in our opinion, quite alarming,” Neves said. Newsweek.

“Before our study, tardigrades were considered the only organism on earth that survived a disastrous event, but now we know that this is not true.”

“[While tardigrades are] one of the most resilient organisms that inhabit our planet, it is now clear that they are vulnerable to high temperatures. That is why it seems that even tardigrades have difficulty coping with rising temperatures due to global warming. “

WHAT ARE TARDIGRADES?

Tardigrades, also known as water bears, would be the most indestructible animals in the world.

These small, segmented creatures come in many forms – there are more than 900 species – and they are found all over the world, from the highest mountains to the deepest oceans.

Tardigrades, also known as water bears, would be the most indestructible animals in the world.

They have eight legs (four pairs) and each leg has four to eight claws that resemble the claws of a bear.

Boil the 1 mm creatures, freeze them, dry them, expose them to radiation and they are so resilient that they are still alive 200 years later.

Water bears can live at temperatures as low as -457 degrees, heat as high as 357 degrees and 5,700 radiation gray, when 10-20 grays would kill humans and most other animals.

Tardigrades have been around for 530 million years and the dinosaurs survived.

The animals can also live without water for a decade and even survive in space.
