To protect its colony, there is a kind of ant that explodes and sprays out a chemical that kills an enemy. A butterfly larva resembles a bird dropping to protect itself from a predator, while a wasp lays its eggs in other larva to provide living food to its young hatchlings. Birds, with no hands for carrying, swallow food and regurgitate it to feed their hungry nestlings, and there is a small worm that lives in and feeds on the mucus in a dog`s nose. This book is filled with fascinating stories of how creatures adapt to the natural world in order to feed themselves, care for their young, and find safety in their environment. Full-color photos.
