Hollywood has made much of the eerie howl of a wolf as the mysterious elements reach a climax. There is always the underlying sense that the listener should be afraid of the appearance of the wolf. Just how dangerous and scary are these wild animals that look like our neighborhood dogs. Wolves are a member of the dog family. They have backbones and fur and feed milk to their young. They stand on four strong legs and have bushy fur that keeps them warm. Wolves live in many habitats, including forests, grasslands, and mountains. A wolf pack, which is what a group of wolves is called, lives together as a family and works together to protect each other and the young wolves. Part of the series "World of Mammals," this series teaches the reader about different mammals, using quick facts and lots of photographs. Although the terms that are defined in the glossary are not indicated in the text, an index, a glossary, and supplemental reading and Internet site pages make this a series worth looking at for older elementary collections and middle school classrooms with reluctant readers. Internet sites are reached by viewing Facthound.com, a database that has already researched the sites and classified them according to age appropriateness. The code needed for accessing this web site is given at the back of the book.
