Sea Otter Heroes, The Predators that Saved an Ecosystem
by Patricia Newman
Millbrook Press, 2017
Why is the Elkhorn Slough, an estuary, where freshwater mixes with ocean water, contain abundant meadows of seagrass, whereas nearly every other estuary on the Pacific coast does not? This book tells the story of a scientist who wondered why and studied the phenomenon until he knew.
With generous photos, charts, graphs, and ‘clues’, author Patricia Newman keeps readers curious and turning the pages, while she discusses each hypothesis the scientist made and discarded during his research. In clear, age-appropriate language, Newman invites readers to do their own thinking. She shows them how much it works to reach the “aha” moment and how much more meticulous work it takes to prove a hypothesis. The book discusses how the findings are applied to other environments. It also includes a section that invites readers to rethink their relationship with wildlife. Sea Otter Heroes is an excellent introduction to science, scientific method, and environmental studies. The science was performed off Monterey Bay, California.
