"Sharks can swim speedily and birds can fly because of physical structures too minuscule to see. Electron-microscope images accompany simple text observations about the importance of unseen, tiny attributes in the physiology of 11 animals: sea snail, shark, blue morpho butterfly, bird, snake, water strider, honeybee, cat, cicada, toucan, and gecko. (Specific species aren't identified for the shark, bird, or snake.) Aspects of strength (tensile and hardness), speed, color, agility, and cleanliness and protection are attributed to fibers and bumps that are invisible to the eye but amazing at very high levels of magnification. Close-up, lower-magnification photos of each animal are also included. A photo of what is presumably a gecko's foot, highly magnified, is one of the best, though it appears on an introductory page and not with the nanoscale microscopic image of the gecko's bristly toes. The backmatter yields some good information and adds factual substance to this visual sampling of microscopic discoveries in biology--a paragraph of explanation for each creature expands on the earlier text; 'nanoscale' is defined with an accompanying graph; and the scanning electron microscope is briefly described. Photos are attributed to stock libraries.

The 'wow' factor in seeing variations in animal adaptations revealed through electron microscopy is compelling. A solid invitation to find out more."--Kirkus Reviews.
