Sometimes the smallest creatures are the most important
The lion may be king of the jungle, but there are plenty of fascinating tiny critters that are critical to the survival of our planet.
From frogs as small as quarters that indicate the health of entire ecosystems, to crayon-sized millipedes that recycle dead plants into vital nutrients for soil, Small but Mighty explores the ways that small creatures help our environment thrive.
Each spread is packed with STEM content, including descriptions of each creature, fun facts, and real-life size comparisons. Illustrations of each animal in its natural habitat, both whimsical and realistic, bring the creatures to life. This kid-friendly introduction to keystone and crucial species and ecosystems demonstrates that no creature—including you!—is too small to make a big difference.
