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.

Nothing prepares you for your first sight of the world’s largest mammal. Celebrated, revered, studied and increasingly watched for pleasure rather than hunted, whales hold particular allure. Humans have always been in awe of them, but for much of history we have been compelled to dominate and kill them – though like Moby Dick, sometimes whales fight back. A Savage History tells the rich history of whales and whaling. We learn about these highly intelligent and magnificent creatures, and follow the stories of whalers from the eighteenth century who hunted their prey along the coasts of Australia and New Zealand, across the Pacific and into the Southern Ocean. The result is a powerful account of a complex and bloody relationship. Although the modern era has seen the end of industrial whaling, as John Newton shows, the work of those who want to protect whales is far from over.
