Parasites are animals, insects, viruses, and microscopic beings that latch onto, trap, trick, and live off of other living things. This series provides a colorful overview of what these yucky creatures are, how they work, what and why they do what they do. Thousands of species of lice plague birds and mammals the world over. A mild infestation is uncomfortable and annoying; a severe infestation can lead to skin infections and disease. This book examines the louse, its effects, and human efforts to combat this parasite.
