With more than 1700 close-up images of live animals, this book is a comprehensive photographic identification guide for field naturalists, serving diving zoologists, educators, as well as hobbyists and people of all ages. This guide is a companion to Fish Watchers Guide to Coastal Sea-Fishes of South-Eastern Australia and illustrates the marine creatures that are free swimming, crawling on the bottom or live on jetty pylons, as well as many of the not so well know cryptics. Port Phillip Bay is the entrance to the Port of Melbourne and is strongly influenced by tides. It has long sandy beaches, seagrass beds, sandstone reefs and many jetties. The southern temperate fauna is extremely rich and diverse.
