Book Description
The polychaetes of the Atlantic coast of New England are still imperfectly known. The present study attempts to give as complete a representation of the New England polychaete fauna as is now possible, to systematize knowledge of the polychaete species known from this New England region of the American coast, and to furnish keys designed to facilitate their identification.

A Practical Guide to the Marine Animals of Northeastern North America
Author: Leland W. Pollock
Publisher: Rutgers University Press
ISBN: 9780813523996
Category : Nature
Languages : en
Pages : 388
Book Description
At last a guide to fish as well as invertebrates with profusely illustrated keys and the most recent terminology! It is not only practical but authoritative as well. A Practical Guide to the Marine Animals of Northeastern North America features Leland Pollock's innovative, user-friendly keys that circumvent many of the difficulties of traditional identification systems. Pollock's keys offer choices among distinctive attributes of the specimen. Results are compared to all variations found in the region's fauna, using a neatly displayed tabular form accompanied by many line drawings.

Reproductive Strategies and Developmental Patterns in Annelids
Author: Adriaan W.C. Dorresteijn
Publisher: Springer Science & Business Media
ISBN: 9401728879
Category : Science
Languages : en
Pages : 314
Book Description
The fascination of the Annelida to scientists lies in the beauty of their structures and the functionality of their body plan, the tremendous adaptive radiation which has made it possible for these animals to colonize almost all marine, limnic and terrestrial biotopes. In doing so they have evolved a great variety of life forms, and their reproduction and development are correspondingly diverse, with many modes and patterns unique in the animal kingdom. In this special volume recent progress in this broad research area is presented by 26 specialists, in general through surveys or treatments of selected examples. Some of them review important annelid taxa such as the Nereididae, Syllidae, Spionidae, Cirratulidae, Clitellata, and Pogonophora; others analyse reproductive and developmental structures and phenomena in annelids, e.g. segmental organs, sex pheromones, oogenesis, mating systems, sperm types, life cycles, larval settlement, cleavage and symmetry of embryos, or discuss controversial approaches to annelid systematics. The book will be of interest to all zoologists who work with annelids as well as to embryologists and other researchers in reproductive biology.

Pleistoannelida, Errantia II
Author: Günter Purschke
Publisher: Walter de Gruyter GmbH & Co KG
ISBN: 3110647168
Category : Science
Languages : en
Pages : 498
Book Description
This book is the fourth in a series of 4 volumes in the Handbook of Zoology series about morphology, anatomy, reproduction, development, ecology, phylogeny and systematics of Annelida. It covers the most typical polychaetes, Phyllodocida, together with certain smaller taxa placed incertae sedis. This volume completes the polychaetous Annelida. Phyllodocida are often vagile, possess well-developed parapodia. Due to their broad and flat cirri these parapodia look like leaves in some taxa and leading to the name of the entire group. Many of its members are macrophagous and often predators. Accordingly most species possess elaborate sense structures such as sensory palps, antennae, eyes and nuchal organs. In certain species the eyes comprise thousands of photoreceptor cells and lenses most likely allowing forming true images. Phyllodocida typically possess an axial muscular pharynx called proboscis functioning as a kind of suction pipe allowing them to swallow and ingest their prey or other food. This pharynx may be armed with cuticular jaws and some species even possess venom glands. The probably most popular and important polychaete model organism, Platynereis dumerilii, belongs to this interesting group. Phyllodocida fall into two to three higher clades comprising about 25 families which represent more than one fourth of the polychaete diversity. One of these families, Syllidae, comprises about 700 valid species of mainly small size and may, therefore, represent one of the most complex and somehow difficult polychaete families on Earth.
