A science journalist's journey along the Pacific Coast from California to Alaska to track the status, health, habits, personality, and viability of sea otters--the appealing species unique to this coastline that was hunted to near extinction in the 18th and 19th centuries. These adorable, furry marine mammals--often seen floating on their backs holding hands--reveal the health of the coastal ecosystem along the Pacific Ocean. Once hunted for their prized fur during the 1700s and 1800s, these animals nearly went extinct. Only now, nearly a century after hunting ceased, are populations showing stable growth in some places. Sea otters are a keystone species in coastal areas, feeding on sea urchins, clams, crab, and other crustaceans. When they are present, kelp beds are thick and healthy, providing homes for an array of sealife. When otters disappear, sea urchins take over, and the kelp disappears along with all of the creatures that live in the beds. Now, thanks to their protected status, sea otters are making a comeback in California, Washington, and Alaska.
Today they’re slowly coming back from the brink, and scientists are learning more about their pivotal role as one of nature’s keystone species. This book looks at the history, biology, behavior and uncertain future of sea otters.
Sea otters are good indicators of ocean health. In addition, they are a keystone species, offering a stabilizing effect on ecosystem, controlling sea urchin populations that would otherwise inflict damage to kelp forest ecosystems.
