Crystal clear close-up photos provide readers with visual access to the world of baby spiders, also known as spiderlings. From egg sac to molting to silk production, the behavior and characteristics of young spiders and their parents are explained in fascinating detail. Spiderlings “become adults when they’re able to mate and produce young of their own,” a period of growth which may take less than a year or more than five years, depending on the species of spider. End materials include a glossary and index, a world map indicating where the spiders in the book were photographed, and a few final captivating facts. (Ages 7–10)
