Only about 10 percent of salmon offspring live to the second stage of the fish's life cycle. Even stranger, they sometimes develop a hump or large teeth before reproducing. Readers learn these bizarre facts and more with colorful photographs and fact boxes detailing other weird salmon information. Written in age-appropriate language, the engaging text introduces readers to important science concepts and includes graphic organizers to aid understanding. Collection Review: Strange Life Cycles"These books deserve attention for far more than their sensational titles. Clearly written, they are bursting with information and intriguing, full-page color photos that enhance understanding of some of nature's most unusual creatures. New vocabulary is introduced on nearly every page and is always well defined in context or in the glossary. … sidebars, life-cycle diagrams, "Fun Facts" pages, charts, and back matter exemplify nonfiction features at their finest. The graphics are as appealing as the content: simple, eye-catching, and bright. Great for research or independent reading, this series may well turn students into budding biologists."-School Library Journal
