Do whales can eat humans?

No, whales cannot eat humans.

Baleen whales have huge mouths that can swallow humans, but due to their short throats keep them from ingesting anything larger than a grapefruit.

Additionally, they use their baleen plates to filter small fish, krill, and plankton from the water.

Furthermore, sperm whales, the only toothed whales capable of consuming people, however, their throats are too tiny to do so.

Overall, whales are not human predators, are gentle giants who pose no threat to anyone swimming or sailing in the water.
