About the Authors
Instructor Resources
  • Each chapter begins with a list of learning objectives that guides the students and focuses their attention on the essential material.
  • More than 500 full-color photographs, illustrations, and dissection diagrams are presented to clarify procedures and help students identify organisms and their anatomical features.
  • Numbered procedures are set apart from the main text, making the labs easier to follow.
  • Adequate space is provided for students to write their answers.
  • Tables are provided throughout the manual to help students summarize key information.
  • "Check Your Progress" questions ensure students are comfortable with the material they learn in each exercise.
  • Chapter-ending questions for review reinforce key concepts and content from the exercises in each chapter.
  • Many chapters contain "Laboratory Practical Challenges" to replicate the method of assessment and type of questions students may be asked on lab practical exams.
  • This manual is customizable.  Chapters 1-14 could be considered for an invertebrate course, and Chapters 1-6 and 15-23 could be considered for vertebrate course.
What's New in this Edition
