Foreword
Most of us at some time or another have enjoyed the relaxing experience of gazing into an aquarium, in a dentist’s waiting room or during a special visit to a public aquarium. In admiring the playfulness of clownfish wriggling amongst the anemones’ tentacles, the grace of angelfish swimming in open water and in our delight at spotting reclusive shrimp and crabs crawling behind iridescent living corals, it is all too easy to overlook the fact that all these wonderful creatures are far from their natural home. The great majority of animals in aquaria across Europe and North America were collected from coral reefs far away and flown, bagged in plastic and packed in styrofoam boxes, thousands of miles to our hospitals and living rooms. 

This clear, heavily-illustrated guide to the human body covers anatomy of cells and tissues, muscle tissue, major muscles of the body, nervous tissue, membranes, organs, cancer, the skin, the human skeleton, the nervous system, glands, the senses, the cardiovascular system, the immune system, the respiratory system, digestion, genitourinary system, the embryo, and more.

An exhaustive review on all things algae would require a multi-volume encyclopedic work. Even then, such a tome would prove to be of limited value, as in addition to being quite complex, it would soon be outdated, as the field of phycology is full of continual revelations and new discoveries.

Phycology is the study of algae, the primary photosynthetic organisms in freshwater and marine food chains. As a food source for zooplankton and filter-feeding shellfish, the algae are an extremely important group. Since the publication of the first edition in 1981, this textbook has established itself as a classic resource on phycology. This revised edition maintains the format of previous editions, whilst incorporating the latest information from nucleic acid sequencing studies.
