These microanimals, which live in both fresh and salt water, are famous for their ability to survive extremes that would kill other organisms. But new research finds that the creatures rapidly wilt under heat. Water temperatures of less than 100 degrees Fahrenheit (37.8 degrees Celsius) can kill tardigrades in only a day. As global temperatures rise, that could become a problem for these animals, the authors of the new study said.

Nutria, also known as coypu or swamp rats, are large rodents that live in areas with lots of freshwater.
These mammals are native to South America and were introduced into the United States between 1899 and 1930 through the fur industry, according to the U.S. Fish and Wildlife Service (FWS). Nutria are now considered a nuisance in the U.S. and other parts of the world where their populations have grown and their presence has disrupted the native ecosystem.
