Sea otters once ruled the Pacific Ocean, but the fur trade of the eighteenth and nineteenth centuries brought this predator to near extinction. 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. Author and photojournalist Isabelle Groc takes us into the field: watching sea otter rafts off the British Columbia coast from a kayak, exploring what makes their fur coats so special, understanding how their voracious appetites are helping kelp forests thrive and, ultimately, learning how sea otters are leaving their mark (or paws) on every part of the ecosystem. They might be one of the most adorable creatures in the ocean, but kids will discover how their survival is key to a rich, complex and connected ecosystem.
