They are found in all oceans, from the Arctic to the Antarctic, and are not considered an invasive species.
Here's why:
* Natural Distribution: Orcas have evolved and lived in their current habitats for thousands of years.
* No Introduction: They have not been introduced by humans to any areas where they didn't naturally occur.
* Ecological Role: Orcas are important predators in their ecosystems and have a vital role to play in maintaining balance.
It's important to note that orcas can sometimes be found in areas outside their typical ranges, but this is usually due to natural migration patterns or changes in prey availability, not human introduction.
