Book excerpt: What is creature design? We all have a notion--mostly consisting of evocative images of otherworldly beings galloping, swimming, flying, and often attacking the hero of an epic film or story. But what makes a creature believable? In the follow-up to her bestseller, Animals Real and Imagined: The Fantasy of What Is and What Might Be, world-renowned artist Terryl Whitlatch reveals the secret behind believable creature design: anatomy. How anatomy applies practically to the natural history and story is the prime cornerstone on which successful creature design hangs, whether the creature is real or imaginary. Studying, understanding, drawing, and applying accurate anatomy to an imaginary creature will make viewers suspend their disbelief to welcome a new vision into their worlds. We invite you to immerse yourself in the intricate workings of numerous animal anatomies--and the beauty they possess--in the Science of Creature Design: Understanding Animal Anatomy. Whitlatch's delightful and charismatic illustrations will inform and thrill readers with every turn of the page. She shares valuable techniques reaped from years working for Lucasfilm and Walt Disney Feature Animation, and on such films as Jumanji, Brother Bear, and The Polar Express. In addition, Whitlatch exemplifies an endless love for real animals that continues to inspire her fantastic imaginary creatures, which have captivated audiences around the world.
