Skickas inom 5-8 vardagar

Twenty years in the making by a distinguished dolphin expert and his associates, "The Hawaiian Spinner Dolphin" is the first comprehensive scientific natural history of a dolphin species ever written. From their research camp at Kealakeakua Bay in Hawaii, these scientists followed a population of wild spinner dolphins by radio tracking their movements and, with the use of a windowed underwater vessel, observing the details of their underwater social life. The authors begin with a description of the spinner dolphin species, its morphology and systematics, and then examines the ocean environment, the organization of dolphin populations, and the way this school-based society of mammals uses shorelines for rest and instruction of the young. The dolphins' reproductive cycle, their vision, vocalization, hearing, breathing, and feeding, and the integration of the school are carefully analyzed. The authors conclude with a comprehensive evolutionary analysis of this marine cultural system, with its behavioral flexibility and high levels of cooperation.This absorbing book is the richest source available of new scientific insights about the lives of wild dophins and how their societies evolved at sea.

The Bottlenose Dolphin presents for the first time a comprehensive, colorfully illustrated, and concise overview of a species that has fascinated humans for at least 3,000 years.

After reviewing historical myths and legends of the dolphin back to the ancient Greeks and discussing current human attitudes and interactions, the author replaces myths with facts--up-to-date scientific assessment of dolphin evolution, behavior, ecology, morphology, reproduction, and genetics--while also tackling the difficult issues of dolphin conservation and management.

Although comprehensive enough to be of great value to professionals, educators, and students, the book is written in a manner that all dolphin lovers will enjoy. Randall Wells’s anecdotes interspersed throughout the work offer a first-hand view of dolphin encounters and research based on three decades working with them. Color photographs and nearly 100 black and white illustrations, including many by National Geographic photographer Flip Nicklin, beautifully enhance the text.
