Sea Otter Heroes: The Predators That Saved an Ecosystem

In California’s Elkhorn Slough, marine biologist Brent Hughes investigates an ecological puzzle: why is seagrass flourishing where algae might have been expected to overwhelm it? His research points toward sea otters, top predators connected to the seagrass at the far end of the food chain. The book follows this scientific discovery and explores how predators can help maintain the balance of an ecosystem.
