The updated and enlarged book includes more than 30 additional species and 70 new photographs. From the beautiful cool waters of Catalina Island to the frigid straits of British Columbia this book covers it all. For more than 3 years, photographers and scientists from around the world have contributed their work to Paul Humann and Ned Deloach to aid in producing this new edition. The result of their extensive work has produced the most up-to-date, accurate and comprehensive reference available for the marine life of the tropical eastern Pacific Ocean from California to Alaska. The new edition features a durable, cloth-stitched flexi-binding that enables the user to lie the book completely flat, perfect for both field and home-office use. More than 320 superb color photos illustrate 258 fish species in a single, compact, beautiful and easy-to-use, no-nonsense natural history field guide. To help simplify the identification process, each fish family is presented within one of 9 Identification Groups based on a family’s visual or behavioral characteristics, such as Silvery Swimmers or Odd-Shaped Bottom Dwellers. Every effort has been made to show the similar-appearing species of a family together for quick reference. The concise text accompanying each species portrait includes the fish’s common, scientific and family names, size, description, visually distinctive features, preferred habitat, typical behavior, depth range, geographical distribution and reaction to divers.
