From the Series Earth's Smallest Superheroes (Real-Life Reads)

  • Interest Level: Grade 2 - Grade 5
  • Reading Level: Grade 3

This fascinating title is a celebration of the chubby, eight-legged, moss-dwelling, microscopic creatures called tardigrades. If you’ve never heard of tardigrades (also known as moss piglets), prepare to be amazed by their superhero survival skills!

Using fantastic photos, 3D artwork, and scanning electron microscope (SEM) imagery, enter the world of the tardigrade and learn how scientists are studying these bizarre superheroes to learn more about the origins of life on Earth and how their survival skills could be used in human medicine.

  • Learn all about the everyday lives of tardigrades
  • Discover how they can be dried out and still survive for years!
  • See how they have been frozen and boiled by scientists—and survived!
  • And be wowed by their journey into space, where they lived without air and with extreme levels of radiation on the outside of a spacecraft—and (you guessed it) survived!
