Do sharks dare to eat blue whales?

Sharks will eat the carcasses of blue whales. It is difficult for sharks to kill blue whales alive because blue whales are much larger than sharks and their sebum is very thick, so sharks cannot do anything to blue whales. Sharks also have their own fixed food chain, and blue whales are not in their food chain.
