The Flea

"The Flea" by Harold Russell is a science book that shines a light on the tiny world of fleas, insects often ignored by scientists in the past. The book explains a lot about fleas, including how they are classified, where they come from, and how they live, using simple and easy-to-understand language. It also shows how important it is to study fleas because they spread diseases like the plague and affect both our health and the environment. It starts by talking about how people haven't paid much attention to fleas, even though scientists have found many new types of fleas recently. The book emphasizes how important it is to learn about fleas, their bodies, how they grow, and which animals they live on.
