Sharks Feasting On A Whale Carcass Blue Planet BBC Earth

They essentially become hubs for an entire deep sea ecosystem for months or even years at a time. Now imagine what would happen if whales went extinct. Countless species of animals who live on the ocean floor, where food can be extremely scarce, would be robbed of what is potentially one of the most important food sources for them. How many absolutely ancient and incredible animals, like those hagfish, sharks, and worms, would subsequently die off as a result of that loss?
