This book was released on 2018-02-18 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Catalog of Living Whales Baleen whales can be arranged phylogenetically on the basis of general form and, secondarily, on size. Rorquals clearly are less specialized than right whales with their exaggerated heads, humps, and baleen plates. Within each group or genus, the smaller and more typically formed or streamlined species is regarded as the more primitive. The evolutionary grade of other mysticete characters, taken singly or in combination, are in accord with the form and size criteria used here. Principal works consulted on the evolution, classification, and biology of whales are listed in the selected bibliography. Others are cited under the generic and specific headings in the systematic section. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book North Atlantic Right Whales written by David W. Laist and published by JHU Press. This book was released on 2017-03-29 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fascinating story of North Atlantic right whales—from their evolutionary origin, through a thousand-year history of relentless pursuit by whalers, to ongoing efforts to rescue them from the brink of extinction. In the cold waters of the unforgiving North Atlantic Ocean, some of the heartiest humans of medieval days ventured out in search of whales. Through the centuries, people on both sides of the Atlantic became increasingly dependent on whale oil and other cetacean products. To meet this growing demand, whaling became ever more sophisticated and intense, leading to the collapse of what was once a seemingly inexhaustible supply of large cetaceans. Central to the whale's subsequent struggle for existence has been one species—the North Atlantic right whale. Conservationist David W. Laist now provides the first complete history of the North Atlantic right whale, from its earliest encounters with humans to its close brush with extinction, to its currently precarious yet hopeful status as a conservation icon. Favored by whalers because of their high yields of oil and superior baleen, these giants became known as "the right whale to hunt," and their numbers dwindled to a mere 100 individuals worldwide. Their dire status encouraged the adoption of a ban on hunting and a treaty that formed the International Whaling Commission. Recovery of the species, however, has proven elusive. Ship strikes and entanglement in commercial fishing gear have hampered herculean efforts to restore the population. Today, only about 500 right whales live along the US and Canadian Atlantic coasts—an improvement from the early twentieth century, but still a far cry from the thousands that once graced Atlantic waters. Laist's masterpiece features an incredible collection of photographs and artwork that give life to the fascinating history that unfolds in its pages. The result is a single volume that offers a comprehensive understanding of North Atlantic right whales, the role they played in the many cultures that hunted them, and our modern attempts to help them recover.

Download or read book Beaked Whales written by Richard Ellis and published by JHU Press. This book was released on 2017-05-08 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: The only book dedicated to the mysterious beaked whale, this beautiful volume combines full-color illustrations with fascinating facts. Beaked whales have been shrouded in mystery for most of the twentieth century. Denizens of deep, remote ocean waters and highly resistant to life in captivity, they have proven notoriously difficult for humans to observe. Over the past few decades, however, scientists have gained a better understanding of this distinct group of cetaceans, deciphering the natural history of the twenty-two beaked whale species. Here, famed artist and naturalist Richard Ellis and leading beaked whale researcher James G. Mead bring these elusive marine mammals into the limelight. Beaked whales’ generous life spans can extend well past 70 years. They spend their decades diving to extreme depths in search of prey, which they capture by expanding their oral cavity suddenly to suck in the squid or fish they are hunting. It appears that these sleek predators may engage in fierce, clandestine aquatic battles, as the bodies of many males are covered in scars. Because many species are only somewhat larger than dolphins, they are often confused with porpoises; however, some larger beaked whale species may grow to 40 feet. These enigmatic and compelling creatures need our help; their numbers are declining, perhaps due to the damaging effects of naval sonar on their sophisticated auditory systems. In Ellis and Mead’s book, the beaked whales finally get their due. The duo provides a combination of captivating stories about the species, original Richard Ellis art, and photos from leading natural history photographers. The result is an accessible, beautiful book—the first of its kind on this unusual group of cetaceans. Meet the beaked whales, and enjoy the fascinating and mysterious world in which they live.
Download or read book Whales of the Southern Ocean written by Yuri Mikhalev and published by Springer Nature. This book was released on 2020-01-28 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on actual data of Soviet whaling, and reliable methodologies that existed at the time when this monograph was written, it examines the distribution and migration patterns of whales of the Southern Ocean. It defines distinct populations on the basis of phenes, as well as whale breeding zones, which are located in the adjacent to the Southern Ocean waters at lower latitudes. The book records the presence of a new species of killer whale in the Southern Ocean - Orcinus nana. Prenatal growth patterns, pregnancy and lactation duration, mean sizes of new-born whales are determined. Methods for the graphic recording of registering structures are described, and an original method for their decoding is proposed to determine animal age. The age of sexual and physical maturity, life expectancy is determined. Earlier unknown “pair formations” on the lower jaw of baleen whales and sperm whales are described, together with their macro, histological and electronic microscopic structure. The impact of the extermination of whales on the Southern Ocean ecosystem is examined, recommendations for control of the current state of whale populations are given, and perspectives of whale population recovery are estimated. Regions that could be used as testing areas for whale registration method are defined. The book is intended for biologist-cytologists, ecologists and other specialists interested in cetaceans, and for biology students.
Download or read book Singing Whales and Flying Squid written by Richard Ellis and published by Rowman & Littlefield. This book was released on 2006-01-01 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-thirds of this planet is covered by water inhabited by an incredible variety of living organisms, ranging in size from microbe to whale, and in abundance from scarce to uncountable. Whales and dolphins must surface to breathe, and some fishes occupy surface waters and can easily be seen from boats or shore, but most of the marine bio-profusion is hidden from human eyes, often under thousands of feet and millions of tons of water, which is usually cold, dark, and utterly inhospitable to humans. By definition, the study of marine life has been quantitatively and qualitatively different from the study of terrestrial life--it is, if you will, a different kettle of fish. What do we know today, how have we learned it, and what remains unknown and unknowable about inner space? Because there have been so few human visitors to the uninviting world of the deep sea, scientists have had to rely on trawled specimens, photographs taken by robotic cameras, or occasionally, observations from deep-diving submersibles, to get even the vaguest idea of the nature of life in the abyss. So far, even our most elaborate efforts to penetrate the blackness have produced only minimal results. It is as if someone lowered a collecting basket from a balloon high above the tropical rain forest floor, and tried to analyze the nature of life in the jungle from a couple of random hauls. The inner space of the deep offers the last frontier on the planet. Even now, we know more about the back side of the moon than we do about the bottom of the ocean, but then the surface of the moon is not hidden under miles of impenetrable water. But we do know that living in this inaccessible medium are some of the most fascinating creatures on Earth. An understanding of the interrelationships between various creatures-including the one predator that has the power to distort, damage, or even eliminate populations of marine animals-is necessary if we are to survive in harmony with these populations. Although new technologies have given us tools to better census the whales, dolphins, and fishes, and to see heretofore unexpected life and geological forms deep under the sea, we are a long way from comprehending the nature and importance of marine biodiversity. Singing Whales, Flying Squid, and Swimming Cucumbers is an attempt to put the search for knowledge into perspective-to try to find out how we got here, and where, with the help of curiosity, science, and technology, we might be headed. With this as our Baedeker, we will voyage through time and space, tracing the history of the discovery of marine biology, from the moment that the first scientists--although for the most part, "science" had barely been invented--tried to figure out what sorts of creatures lived in the Mediterranean, the sea right off their shores. So join Richard Ellis on an underwater adventure like no other you've ever taken or heard of: a voyage to discover the mysteries and reveal the wonders of marine life--more unusual and more astonishing than you--or anyone else--ever imagined.
