Nature's Ninja

Animals with Spectacular Skills

  • Interest Level: Grade 4 - Grade 8
  • Reading Level: Grade 5

Ninja were skilled warriors in medieval Japan. And now you can find ninja in comics, movies, and TV shows. But what about in nature? Real animals aren’t anything like ninja . . . are they?

A stealthy lizard that can climb walls and hang upside down by its toes? Yes! A sea creature that defends itself with weapons that look a whole lot like throwing stars? Definitely! An insect that blends in so well with its enemies that they never even know it’s there? Yes again!

Encounter geckos, sea urchins, rove beetles, and many other living things that have more in common with ninja than you might expect. And hear from the scientists who are working to understand just how these animals are able to do what they do.

Science meets martial arts in this fun and fast-paced look at some truly incredible animals.
