Sea otters A survival story

Gr 4--7--Sea otters are cute, smart, and endangered. Author and wildlife photographer Groc shows readers the history of sea otters, their recovery from near-extinction, and what people can do to help save these marine animals. The book features full-color photographs and, much like its series predecessors, the text explains how humans have made an impact on a species and provides conservation tips. The book describes what otters eat, where they live, how they raise their pups, and the difficulties prey, humans, and changing ecosystems have imposed on them throughout the years. Nested between chapters are sections ("In the Field") where a biologist or person who works closely with sea otters discusses their job or role in helping sea otters thrive. VERDICT This very relevant book on climate change and endangered species is a strong choice for all nonfiction collections. Give to readers who are interested in books that show how to make a real difference for the overall welfare of the planet.--Anna Taylor, Darien Library, CT

Sea otters, nearly driven to extinction by human fur-hunters, have bounced back and surprised scientists with their importance to their environment. In this account of species survival, part of the Orca Wild series, writer and wildlife photographer Groc argues forcefully for the importance of sea otters to their ecosystem, not only along the coasts of the northern Pacific Ocean, but also in its estuaries. She describes the nature and habits of these intriguing sea mammals as well as the historical effect of their loss on their surrounding natural world. When the otters disappeared, so did the kelp forests, but sea urchins, clams, and other invertebrates thrived. With their reintroduction, the kelp grew rapidly, and the invertebrates became more difficult to harvest or disappeared. Though clearly on the side of the otters as "ecosystem engineers" at the top of the food chain, she also presents the points of view of fishermen and Indigenous peoples who had relied on the shellfish. "In the Field" sections introduce scientists (both male and female, mostly white-presenting), citizen-science volunteers, and First Nations members, offering a variety of perspectives. The text flows smoothly and often includes personal examples. Groc's photographs, taken in Alaska, British Columbia, and California, demonstrate the animal's appeal. Patricia Newman's Sibert Honor book Sea Otter Heroes (2014) focuses on the estuary research; this well-researched portrayal is a broader look suitable for the same audience. A thorough introduction to an appealing keystone species. (glossary, resources, acknowledgments, index not seen) (Nonfiction. 10-15) Copyright (c) Kirkus Reviews, used with permission.
