Some of the most intriguing elements of survival in the animal kingdom are the unusual--and occasionally downright bizarre--eating habits that animals have developed. One animal's leftovers or excretions may be a great source of nutrition for another. For instance, porcupines feed on deer antlers to obtain calcium; Dungeness crabs will often eat their own offspring to replenish essential proteins; vampire bats must lap up half their body weight in blood each night in order to stay healthy. Mammals, birds, and insects have adapted to their environments by eating some very surprising foods--all the while making excellent use of what nature has to offer. Filled with intriguing facts, this innovative picture book explores animal diet and cuisine with just the right mix of intelligence and humor.
