The Predator That Saved an Entire Ocean Forest

What happens when one small predator disappears from the ocean? Along the Pacific coast of North America, the loss of sea otters allowed sea urchins to multiply and destroy vast underwater kelp forests. But when the otters returned, the ecosystem began to recover — bringing back fish, seabirds, whales, and even connections to animals living on land. This documentary explores how the sea otter transformed an entire coastline and became one of the most important “keystone species” in the marine ecosystem.
