From School Library Journal
Grade 4–8—This unique title uses geometry to discuss the varying strengths and capabilities of different animals. In a chatty tone, Davies starts off by describing the strict rules that control what bodies can and cannot do. She goes on to explain how the strongest animals are much smaller than humans. "Some important features of bodies—like how much food and air they need—depend on volume and weight. Others—like the strength of muscles—depend on cross section or surface area." This is the basis for the BTLT (Big Thing, Little Thing) Rule: "If you DOUBLE the length of something, its surface area and cross section go up FOUR times, while its volume and weight go up EIGHT times!" BTLT is used throughout to explain why humans cannot fly, yet Arctic terns can travel 20,000 miles every year from pole to pole and back again. Humans cannot lift buses, but the rhinoceros beetle can lift 850 times its own weight. The author uses clear language and engaging examples throughout. Cartoon illustrations add humor and clarity to the book. A handy introduction to animal sizes.—Anne Chapman Callaghan, Racine Public Library, WI

This book takes on what seems like an abstract and uninteresting topic--the issue of animal size. But Davies manages to make it relevant. Why can't giant spiders exist? Why can't humans be superheroes who can lift up buses? Davies explains why using a "Big Thing/Little Thing" rule, or BTLT, which she refers to again and again. Her writing style interested both of my sons. While the 10 year old enjoyed the concept, my 4 year old was drawn to the cartoon-style pictures. And, I must admit, I was very relieved to read that my fear of giant spiders is unfounded--they simply can't exist. Whew!
For writing teachers, this book will be a great mentor text. There are so many good things going on--an interesting beginning, strong voice, cartoons to illustrate key concepts, and a conclusion that ties everything together. In the reading classroom, I see this book as an expository text that will be irresistible to kids who like graphic novels. Don't miss this one!
The accompanying cartoon shows a herd ofwildebeasts passing a sign saying "last fresh grass for 1800 miles" a contradiction of the text. And it gets worse.`
