However, there are a few things to consider:
* Orcas (killer whales) are known to prey on young, sick, or injured baleen whales, especially gray whales.
* Humans pose a significant threat to baleen whales through hunting, fishing bycatch, and habitat destruction.
* Parasites can affect baleen whales' health, sometimes leading to death.
So, while baleen whales don't have specific predators in the traditional sense, they are vulnerable to various threats.
