Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Handbook of Zoology, Vol. 2 of 2: Vertebrate Animals The argument for the animal nature of all organisms present ing pulsatory spaces is strengthened by the fact that in very many instances vessels have been shewn to be in connexion with these Spaces or vesicles, and hence by the probable inference that where there is a pulsatory vesicle there also a vascular system exists.

Download or read book Miscellaneous Invertebrates written by Andreas Schmidt-Rhaesa and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-03 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the Handbook of Zoology summarizes "small" groups of animals across the animal kingdom. Dicyemida and Orthonectida are enigmatic parasites, formerly united as "Mesozoa" and their position among the multicellular animals is still not known with certainty. Placozoa are small, flat marine animals which provide important information on metazoan evolution. Comb jellies (Ctenophora) are esthetically fascinating animals which cause considerable discussion about their phylogenetic position. Seisonida are closely related to rotifers and acanthocephalans. Cycliophora were discovered and described as one of the last higher taxa and surprise by their complex life cycle. Kamptozoa (= Entoprocta) are small sessile animals in the sea and sometimes also in freshwater. Arrow worms (Chaetognatha) play an important role as predators in the plankton, but they also include benthic forms. Pterobranchia and acorn worms (Enteropneusta) belong to the deuterostomia and are related to echinoderms. In particular enteropneusts play an important role in understanding deuterostome evolution. These chapters provide up to date reviews of these exiting groups with reference to the important literature and therefore serves as an important source of information.
Download or read book Nematoda written by Andreas Schmidt-Rhaesa and published by Walter de Gruyter. This book was released on 2013-12-18 with total page 775 pages. Available in PDF, EPUB and Kindle. Book excerpt: This section of the Handbook of Zoology is intended as a comprehensive and exhaustive account of the biology of the taxa Gastrotricha, Nematoda, Nematomorpha, Priapulida, Kinorhyncha, Loricifera, Gnathostomulida, Micrognathozoa, Rotifera, Seisonida and Acanthocephala, covering all relevant topics such as morphology, ecology, phylogeny and diversity. The series is intended to be a detailed and up-to-date account of these taxa. As was the case with the first edition, the Handbook is intended to serve as a reliable resource for decades. Many of the taxa of this volume are comparatively unknown to many biologists, despite their diversity and importance for example in meiofaunal communities (Gastrotricha, Rotifera, Gnathostomulida), their fascinating recent discoveries (Loricifera and Micrognathozoa), their importance as parasites (many nematodes, Nematomorpha, Acanthocephala) and their importance for evolutionary questions (e.g. Priapulida, Gastrotricha). The groups covered range from those poor in species (such as Micrognathozoa with 2 known species) to the species-rich and diverse Nematoda and their ca. 20.000 described species. While each taxon is covered by one chapter, nematodes are treated in several chapters dedicated to their structural, taxonomic and ecological diversity.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Text-Book of Zoology, Vol. 2 of 2 IN the arrangement which it has been found convenient to follow in the present work, the Vertebrate animals (fishes, Amphibians, Reptiles, Birds, and Mammals), together with the Cephalochorda or Lancelets, the Urochorda or Ascidians, and the Hemichorda or Balanoglossus and its allies, are all grouped together in a single phylum - the Chordata. The main groups comprised in this assemblage, however, differ so widely from one another' in certain essential points, and the common features uniting them together are so few, that it has been thought advisable to depart from the plan of arrangement followed in connection with the rest of the phyla, and to make a primary division in this case not into classes, but into sub-phyla. In accordance with this scheme the phylum Chordata is regarded as made up of three sdb-phyla - the Hemichorda, the Urochorda, and the Euchorda, the last-mentioned comprising the two sections Acrania and Craniata or Vertebrate, each of which receives separate treatment.

Download or read book Annelida written by Günter Purschke and published by Walter de Gruyter GmbH & Co KG. This book was released on 2019-03-18 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first in a series of 4 volumes in the Handbook of Zoology series about morphology, anatomy, reproduction, development, ecology, phylogeny and systematics of Annelida. This first volume covers members of the so-called basal radiation and the first part of Sedentaria. It is supplemented by chapters on the history of annelid research, their fossil record, and an introduction to the phylogeny of annelids and their position in the tree of life. In the latter chapter the history of their systematic is reviewed giving an almost complete picture of systematic-scientific progress especially in the past years which changed our view on annelid phylogeny dramatically. The most basal annelids, lately united as Palaeoannelida, represent two families of aberrant polychaetes formerly often suggested to be highly derived which now give us a fresh look on how the ancestral annelid may have looked like. These lack certain key characters such as nuchal organs and possess rather simple nervous systems which now likely represent primitive character states. In this basal radiation the first taxon of apparently unsegmented and achaetigerous animals is positioned, the Sipuncula. Most likely another group of platyhelminth-like and unsegmented and even chaeta-lees annelids, Lobatocerebridae falls into this basal radiation. The section of Sedentaria starts with Orbiniida, a taxon characterized by elongated, thread-like worms which do not have anterior appendages like palps and comprises several families representing members of the Meiofauna. These minute worms often inhabiting the interstitial spaces in marine sands are suggested to have evolved by progenesis. The second higher taxon is represented by Cirratuliformia comprising nine families of typical sedentary polychaetes each of which showing a remarkable variation of the annelid body plan. Members of this taxon usually exhibit many annelid characters but certain also lack the most typical prostomial appendages, the palps.
