Download or read book Hagfish Biology written by Susan L. Edwards and published by CRC Press. This book was released on 2015-09-14 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: With over 70 species still populating the world’s oceans after approximately 500 million years, hagfishes are essential benthic organisms that play a vital role in understanding the evolutionary origins of vertebrate life and the maintenance of the oceanic ecosystem. Hagfish Biology is a long overdue book for communicating and furthering study on these unique animals. It provides an avenue of synergy among scientists interested in hagfish physiology, molecular and evolutionary biology, morphology, and protection. New high throughput sequencing technologies, advanced microscopy techniques, descriptions of hagfish embryology, and developments of techniques to understand ancient evolutionary relationships have led to a resurgence of interest in the hagfish as a key species in understanding the evolution of vertebrates. Inspired by these new research perspectives, this book compiles scientific information on hagfishes that is of interest to a range of fields such as ecology and evolution, comparative physiology, and conservation biology. A much-needed contribution, Hagfish Biology builds on previous knowledge while encouraging further expansion of scientific interest and learning about this fascinating yet understudied key evolutionary species. It introduces you to developing areas of research and provides beginning points for a larger conversation on hagfishes.
Download or read book The Biology of Hagfishes written by Jørgen Mørup Jørgensen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hagfishes comprise a uniform group of some 60 species inhabiting the cool or deep parts of the oceans of both hemispheres. They are considered the most primitive representatives of the group of craniate chordates, which - apart from the hagfishes that show no traces of verte brae -includes all vertebrate animals. Consequently the hagfishes have played and still playa central role in discussions concerning the evolution of the vertebrates. Although most of the focus on hagfishes may be the result of their being primitive, it should not be forgotten that, at the same time, they are specialized animals with a unique way of life that is interesting in its own right. It is now more than 30 years since a comprehensive treatise on hagfishes was published. The Biology of Myxine, edited by Alf Brodal and Ragnar Fange (Universitetsforlaget, Oslo, 1963), provided a wealth of information on the biology of hagfishes, and over the years remained a major source of information and inspiration to students of hagfishes.

Download or read book How to Snog a Hagfish written by Jonathan Eyers and published by A&C Black. This book was released on 2012-04-09 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: How to Snog a Hagfish! explores the most bizarre, the most disgusting and the most fascinating creatures that inhabit the oceans. When attacked, the hagfish (also known as the slime eel) ties itself in a knot that travels the length of its body, squeezing out mucus by the bucketful and making it impossible for a predator to keep hold. To eat, a starfish regurgitates its stomach, digests its food then swallows its stomach back down again. Pearlfish stick close to sea cucumbers, whose bowels they swim into when danger's near. And with shark attacks and jellyfish encounters, the oceans take on another level of repulsiveness when man dips his toes in the water. We know more about the surface of the moon than we do the underwater world, but some of the species covered in this book are beyond even the imagination of science fiction writers. Entertaining yet informative, the idea of this book is not to wallow in grossness with the intention of putting people off their dinner, but to explore just how fascinating and 'alien' our own planet can be. Highly illustrated, and with stories and anecdotes that help bring a human perspective, this book demystifies the natural world beneath the waves, and shows how it's not quite so shocking when you understand why these creatures have developed the way they have.
Download or read book Reproductive Biology and Phylogeny of Fishes Vol 8B Part B Sperm Competion Hormones written by Barrie G M Jamieson and published by CRC Press. This book was released on 2019-09-12 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: The animals loosely termed fish constitute more than half of all known vertebrate species. There are approximately 27,000 described living species of bony fishes (Euteleostomi = Osteichthyes), about 70 species of hagfishes and some 34 species of lampreys. Approximately 970 species are chondrichthyans, the sharks and their relatives, which were the subject of volume 3 in this series. It is perhaps because fishes live in a buoyant medium, whether it be fresh or sea water, that they show a diversity in body shapes that is unparalleled by other vertebrates. There is also a unique diversity in the modes of reproduction, whether by external or internal fertilization, and this, with the morphology and fine structure of the reproductive system and its components, is the subject of Part A. Part B deals with complementary topics: testes, sperm, and sperm competition; endocrinology of reproduction; pheromones and reproduction; copulatory structures: taxonomic overview and the potential for sexual selection; sexual selection: signaling and courtship; adaptation and evolution of reproductive mode in copulating cottoid species; fertilization; sex determination; parental care; reproduction in relation to conservation and exploitation of marine fishes; Cryopreservation of Gametes; Embryogenesis and Development; and Molecular Genetics of Development.
Download or read book Hormones and Reproduction of Vertebrates Volume 1 written by David Norris and published by Academic Press. This book was released on 2011-05-04 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series of volumes represents a comprehensive and integrated treatment of reproduction in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable, coordinated description of reproductive basics in each group of vertebrates as well as an introduction to the latest trends in reproductive research and our understanding of reproductive events. Whereas each chapter and each volume is intended to stand alone as a review of that topic or vertebrate group, respectively, the volumes are prepared so as to provide a thorough topical treatment across the vertebrates. Terminology has been standardized across the volumes to reduce confusion where multiple names exist in the literature, and a comprehensive glossary of these terms and their alternative names is provided. A complete, essential and up to date reference for research scientists working on vertebrate hormones and reproduction - and on animlals as models in human reproductive research Covers the endocrinology, neuroendocrinology, physiology, behaviour and anatomy of vertebrate reproduction Structured coverage of the major themes for all five vertebrate groups allows a consistent treatment for all Special chapters elaborate on features specific to individual vertebrate groups and to comparative aspects, similarities and differences between them
