With over 14,700 entries, this dictionary is the most comprehensive reference work of its kind available today. It fulfills the need for a zoological work that combines the concise presentation of a dictionary, a brief etymology for each term, and the inclusion of the general terms one would meet during a zoology course. Vertebrate zoology is not studied in isolation, therefore the more common terms from the fields of Anatomy, Animal Behavior, Biochemistry, Cell Structure and Function, Cytology, Earth History, Ecology, Embryology, Endocrinology, Evolution, Genetics, Palaeontology, Physiology, Taxonomy and Zoogeography have been included. There is comprehensive taxonomic coverage of every vertebrate family and many species that are of particular interest. Appendices give an outline classification of the animal kingdom and provide an overview of geological time. This dictionary is the standard reference and will be invaluable to those with an interest in zoology.
