Wolves Have Taken Over a Marine Ecosystem

The video explores the unique ecosystem on Pleasant Island, Alaska, where wolves have become apex predators in a marine environment. Initially feeding on deer, the wolves shifted to sea otters as their primary food source. This shift highlights the role of sea otters in maintaining kelp forests and ecosystem balance. The coexistence of wolves and sea otters offers a rare opportunity to study interactions between two apex predators. Despite concerns, the wolves' diet appears sustainable, allowing them to thrive without depleting the sea otter population.
