In this I Can Read! book, Thomson takes a look at blue whales, killer whales, sperm whales, dolphins, and porpoises, describing common physical characteristics of the group as well as hunting and feeding habits, methods of communication, and endangered status. Large, full-color photographs from the Wildlife Conservation Society appear on nearly every page, depicting the cetaceans engaged in a variety of activities. Although the photos are crisp and well chosen, a few contain details (barnacles and debris attached to the skin) that are not addressed in the text. The writing is clear and packed with information, and, without resorting to anthropomorphism or fictionalization, Thompson presents raw data in a way that will be meaningful to kids (A blue whale is as long as a basketball court). This will be a great addition to the easy reading section, where nonfiction titles are sometimes scarce; animal lovers will grab it right up.

Early readers will appreciate large, well-spaced typeface over full-page Wildlife Conservation Society photos in these fact-filled, well-organized narratives. Simple page layout aids focus on the subject matter--gorillas in families and at play, and whales as the earth's largest water mammals--each studied and appreciated by scientists, and both "[needing] our help to survive."

Gr 1-3-Thomson's superior text sustains readers' attention with interesting facts and apt comparisons, such as, "A killer whale is about as long as a fire truck" and "Baleen is made of the same stuff as your fingernails." The book evokes a sense of having a conversation with a knowledgeable, friendly expert. Words are defined within the text. For beginning readers, this is much easier than referring to a glossary because it keeps the terms in context and allows the text to flow with minimal interruption. Spectacular color photographs add detail and drama, with some intimate close-ups of the magnificent mammals. The book ends with a few pages about whale conservation and raises questions that suggest the need for further investigation, and may serve as a springboard for rich classroom discussion. This is an excellent choice, particularly where hi/lo titles are needed. The author has managed to strike a balance between simplicity and rich content.-Mary Hazelton, Warren Community School and Miller Elementary School, ME Copyright 2004 Reed Business Information.
