5 Fun Facts about Orcas for World Orca Day

5 quick and fun facts to know about orcas – or killer whales – on World Orca Day:

  1. Orcas are found in all oceans around the world.

  3. They are extremely social mammals that live in pods, usually with the same family members their entire lives. Pods can range from 5 to 10 members and can even merge to become super pods with as many as 100 whales.

  5. You can determine a killer whale’s sex by their dorsal fin: males’ or bulls’ fins are not curved and can grow up to 6 feet in height, while females’ or cows’ fins are shorter and curved.

  7. Orcas have a fatty layer of blubber under the skin that acts like fur and insulation to keep warm and can also be converted for energy when food is scarce.

  9. Wild orcas are not considered a threat to people.
