What eats baleen whales?

Baleen whales are at the top of the food chain, so there are no natural predators that eat them.

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.
