They are powerful, intelligent, and highly social animals. Their size and hunting skills make them formidable predators, and they are not typically targeted by other animals.
However, there have been isolated cases where:
* Larger sharks (like Great Whites) might occasionally attack young orcas.
* Adult male orcas may sometimes prey on other orcas, particularly if they are competing for mates or resources.
Overall, orcas are at the top of the food chain, and they do not have any significant natural predators.
