Book excerpt: Zoology, Volume 16: The Evolution of the Metozoa presents the significant results of the Cnidaria research, their interpretations and implications in the field of zoology. This book is composed of four chapters, and begins with the establishment of the systematic position of the Spongiae, the position of Ctenophora in the animal classification, and Cnidaria as the only Coelenterata. The subsequent chapter deals with a critical survey of the interpretations of the origin and nature of Cnidaria, with emphasis on the morphologic proofs of its phylogeny. These topics are followed by an outline of the most probable reconstruction of the phylogeny of Cnidaria and the descriptions of the evolution of this metozoa. The final chapter considers the established classification of the animal world and the genealogical tree. This book will be of value to zoologists and researchers who are interested in evolution and classification of Cnidaria.

Download or read book Coelenterate Ecology and Behavior written by G.O. Mackie and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 723 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of coelenterates is now one of the most active fields of invertebrate zoology. There are many reasons for this, and not everyone would agree on them, but certain facts stand out fairly clearly. One of them is that many of the people who study coelenterates do so simply because they are interested in the animals for their own sake. This, however, would be true for other invertebrate groups and cannot by itself explain the current boom in coelenterate work. The main reasons for all this activity seem to lie in the considerable concentration of research effort and funding into three broad, general areas of biology: marine ecology, cellular-developmental biology and neurobiology, in all of which coelenterates have a key role to play. They are the dominant organisms, or are involved in an important way, in a variety of marine habitats, of which coral reefs are only one, and this automatically ensures their claims on the attention of ecologists and marine scientists. Secondly, the convenience of hydra and some other hydroids as experimental animals has long made them a natural choice for a variety of studies on growth, nutrition, symbiosis, morphogenesis and sundry aspects of cell biology. Finally, the phylogenetic position of the coelenterates as the lowest metazoans having a nervous system makes them uniquely interesting to those neurobiologists and behaviorists who hope to gain insights into the functioning of higher nervous systems by working up from the lowest level.
