In November 2005, Washington's iconic killer whales, known as Southern Resident orcas, were placed on the endangered species list. It was a victory long overdue for a fragile population of fewer than one hundred whales. Author and certified marine naturalist Sandra Pollard traces the story and destinies of the many Southern Resident orcas captured for commercial purposes in or near the Puget Sound between 1964 and 1976. During this time, these highly intelligent members of the dolphin family lost nearly one-third of their population. Drawing on original archive material, this important volume outlines the history of orca captivity while also recounting the harrowing struggle--and ultimate triumph--for the Puget Sound orcas' freedom.

"Weaving decades of field observations with exciting new discoveries about the brain, Carl Safina's landmark book offers an intimate view of animal behavior to challenge the fixed boundary between humans and nonhuman animals. In Beyond Words, readers travel to Amboseli National Park in the threatened landscape of Kenya and witness struggling elephant families work out how to survive poaching and drought, then to Yellowstone National Park to observe wolves sort out the aftermath of one pack's personal tragedy, and finally plunge into the astonishingly peaceful society of killer whales living in the crystalline waters of the Pacific Northwest. Beyond Words brings forth powerful and illuminating insight into the unique personalities of animals through extraordinary stories of animal joy, grief, jealousy, anger, and love. The similarity between human and nonhuman consciousness, self-awareness, and empathy calls us to re-evaluate how we interact with animals" --
