"Uncommonly useful... Solid additions to science collections." --Booklist

"The Arachnid World series looks at animals that are often confused with insects but are actually in a class by themselves. After introducing arachnids, each book looks more closely at one type, discussing its physical structure, life cycle, and characteristic behaviors. Large color photos, sometimes highly magnified, appear throughout the books and illustrate the text quite well. One uncommonly useful feature in each book is the pair of double-page spreads showing the animal's body, inside and out. First, a photo of the arachnid appears with its visible parts clearly labeled and certain features discussed more fully. Next, a large-scale cross section shows the critter's innards, with an arrow pointing out each significant organ and leading to related text boxes. In Mites, Markle discusses a variety of these usually tiny, sometimes parasitic creatures. Tarantulas looks at the lives of these large, hairy spiders and points out that they help control insect populations. Wind Scorpions introduces a group of arachnids that use supersize jaws to defend themselves and to attack their prey. Each volume concludes with a glossary, an activity, and short, annotated lists of books and websites. Solid additions to science collections." --Booklist

"Valuable resources for both students and arachnophiles alike." --School Library Journal

"These well-crafted introductions take a close look at arachnids with extraordinary attributes. In each title, a succinct text describes general characteristics; major physical and behavioral characteristics shared by all of the featured invertebrates; distinctive traits of particular species; habitats; life cycles; feeding habits and diets, etc. Each book concludes with a story outlining the lives of representative males and females, from birth to reproduction as adults. Sharp, close-up color photos (extreme close-ups in Mites) depict each stage of their life cycles. In some sections, a photo appears on every page; in others, a full-page close-up alternates with each page of text. About a dozen species are depicted in Tarantulas and Mites, four in Wind Scorpions. Highlighting each title are detailed, double-page, anatomical diagrams of both external and internal key body parts. Hexagon-shaped sidebars, scattered throughout, offer additional facts. Addenda include information on related arachnids and a simple activity demonstrating a behavior discussed in the text (feeding, molting, etc.). Mites and Tarantulas offer more detail on anatomy than other introductions, such as Carrie Gleason's Feasting Bedbugs, Mites, and Ticks (Crabtree, 2011) and Alice B. McGinty's The Tarantula (Rosen, 2002); they also describe mating (and depict it in Tarantulas), which these earlier titles do not. As there is little information available on wind scorpions, Markle's books will also help fill a gap. Valuable resources for both students and arachnophiles alike." --School Library Journal
