Yachts sailing the oceans are regularly sunk by Whales. Lives at sea are at risk and it is an increasing problem. This book explores the facts and gives a few tips on how to avoid Whales when racing or cruising the oceans and how to minimize the event of Whales attacking your vessel.

Could you survive being lost in the Pacific ocean for 38 days? The Robertson Family: Attacked by Orcas in the True Survival series explores the Robertson's shocking survival story. The book is written with a high interest level and lower level of complexity to serve more mature students reading at lower levels. Clear visuals, colorful photographs (including images of the survivors!), and considerate text help with comprehension and wild facts hold the readers' interest from the first page to the last. This book includes a table of contents, glossary, index, author biography, and sidebars.

Famed in story as "the great leviathans," sperm whales are truly creatures of extremes. Giants among all whales, they also have the largest brains of any creature on Earth. Males can reach a length of sixty-two feet and can weigh upwards of fifty tons. With this book, Hal Whitehead gives us a clearer picture of the ecology and social life of sperm whales than we have ever had before. Based on almost two decades of field research, Whitehead describes their biology, behavior, and habitat; how they organize their societies; and how their complex lifestyles may have evolved in this unique environment. Among the many fascinating topics he explores is the crucial role that culture plays in the life of the sperm whale, and he traces the consequences of this argument for both evolution and conservation. Finally, drawing on these findings, Whitehead builds a general model of how the ocean environment influences social behavior and cultural evolution among mammals as well as other animals. The definitive portrait of a provocative creature, Sperm Whales will interest animal behaviorists, conservationists, ecologists, and evolutionary biologists as well as marine mammalogists.

This book constitutes the refereed proceedings of 5 workshops held at the 21st International Conference on Financial Cryptography and Data Security, FC 2017, in Sliema, Malta, in April 2017.The 39 full papers presented were carefully reviewed and selected from 96 submissions. They feature the outcome of the 5th Workshop on Encrypted Computing and Applied Homomorphic Cryptography, WAHC 2017, the 4th Workshop on Bitcoin and Blockchain Research, BITCOIN 2017, the Second Workshop on Secure Voting Systems, VOTING 2017, the First Workshop on Trusted Smart Contracts, WTSC 2017, and the First Workshop on Targeted Attacks, TA 2017.The papers are grouped in topical sections named: encrypted computing and applied homomorphic cryptography; bitcoin and blockchain research; advances in secure electronic voting schemes; trusted smart contracts; targeted attacks.

Ocean currents, winds, and rainfall all work together to create a marine oasis around the Hawaiian Islands, providing a home for many species of dolphins and whales normally found in the deep oceans of the world. The Lives of Hawai`i’s Dolphins and Whales opens a window into the world of these mysterious creatures with stories and observations from author Robin W. Baird’s work over the last seventeen years. The book includes exceptional full-color photographs of each species, life history descriptions, conservation threats, and maps showing sighting locations and movements of tagged individuals among the islands and offshore. While the well-known resident spinner dolphins and visiting humpback whales are covered, the ten species of lesser-known open-ocean dolphins and whales that are resident to the marine slopes of the islands are highlighted as well. Among these are endangered false killer whales, deep-diving Cuvier’s and Blainville’s beaked whales, abundant spotted dolphins, coastal bottlenose dolphins, cryptic dwarf sperm whales, family units of short-finned pilot whales, and social melon-headed whales. Baird also describes thirteen species of dolphins and whales that are found in offshore waters or are seasonal or occasional visitors to Hawaiian waters, including killer whales, the iconic sperm whale, and even blue whales and North Pacific right whales. More is known about the social organization and natural history of many of these marine mammals in Hawai`i than anywhere else in the world. For all of the species discussed, Baird presents data obtained from long-term photo-identification studies, with distinctive individuals tracked through time and space; for many of them, he includes findings from studies using genetics and satellite tagging. He also provides information on predators and prey, social organization, diving, and night-time behavior, along with suggestions on how to tell some of the more difficult to identify species apart. The book closes by focusing on conservation issues, both success stories and challenges, engaging readers to consider ways to protect Hawai`i’s unique assemblage of resident dolphins and whales.

"A must read for anyone interested in the ecology of whales, this timely and creative volume is sure to stimulate new research for years to come."—Annalisa Berta, San Diego State University

This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.
