Shark attacked and eaten by giant Moray eel

Sharks are typically apex predators, and it's quite rare for them to be attacked and eaten by other marine creatures. While Moray eels are formidable predators in their own right, instances of them attacking and eating sharks are extremely uncommon. Sharks generally have a higher position in the marine food chain. However, in the natural world, unexpected events can occur. If you have a specific incident in mind, I'd need more details to provide further information.
