Trivia: The microscopic tardigrades are also known by what nickname?
Sky snakes
Swamp penguins
Water bears
Lava lemurs
The correct answer is Water bears
So why is this answer correct? : Water bears are among the strangest animals humans have discovered. The microscopic, eight-legged creatures are essentially invisible to the human eye, reaching only about half a millimeter in length. They’re part of an elite category of creatures known as extremophiles, meaning that they can survive in environments that would typically be considered inhospitable. Tardigrades can go up to 30 years without food or water and have been found in both freezing cold places and boiling water. They can even live in the empty vacuum of outer space.
