Here's why:
* Different roles in the ecosystem: Whales and sharks occupy different niches in the ocean. Whales are usually much larger than sharks and eat krill, fish, and other smaller animals. Sharks are predators, but most species are not large enough to threaten adult whales.
* Some sharks eat whale carcasses: Some shark species will scavenge on dead whales, but that's a natural part of the food chain.
* Natural interactions: There are occasionally reports of sharks attacking whales, but these are rare. Most encounters are likely to be accidental or driven by the shark's instinct to investigate something unusual.
So, while the idea of whales hating sharks is fun, it's not a real thing. Whales and sharks generally co-exist in the ocean, and their interactions are mostly neutral.
