New to the ninth edition are Learning Outcomes and Learning Outcome Review questions. Learning Outcomes help students identify and focus on the major concepts of each chapter. Learning Outcomes Review questions conclude each major concept to reinforce critical concepts students have just studied and include critical thinking questions that assess their understanding of those concepts. This edition offers:

• Connect® Plus for Zoology, which provides teachers with auto-gradable and interactive assessment material tied to learning outcomes and provides better integration for students through live eBook links to animations, videos and audio assets.
• A lab manual correlated to the textbook for greater integration of labs into the course instruction.
