There’s always something new to discover about the remarkable black-and-white creatures of the sea.

Here are 10 fascinating facts about orcas that offer a deeper insight into these incredible marine mammals!

1. Orcas Are the Largest Dolphin Species

Orcas (Orcinus orca), often called killer whales, are the largest members of the dolphin family. While most dolphins feed on fish and small crustaceans, orcas, particularly Bigg’s killer whales, are known to hunt marine mammals, including seals and even other whales.

2. Orcas Are Speedy Swimmers

With their powerful build, orcas can reach speeds of up to 30 knots (34 mph), making them some of the fastest marine mammals.

3. Orcas Can Grow Massive

Orcas can grow up to 26 feet in length and weigh as much as six tons—roughly the size of a small school bus. Imagine how impressive that would be in the water!

4. Orcas Live in Every Ocean

From the Arctic to the Antarctic, orcas can be found in all of the world's oceans. With over 50,000 estimated individuals, these remarkable creatures roam vast distances across the globe.

5. Orcas Are Masterful Hunters

Orcas are highly skilled hunters that use teamwork to catch prey. Some even beach themselves to catch sea lions or create waves to push prey off ice floes, showcasing the intelligence and coordination within orca pods.

6. Orcas Have Their Own Culture

Each orca pod has its own dialect, and behaviors like hunting techniques are passed down through generations. This cultural transmission is a unique trait shared only by humans.

7. Female Orcas Have Long Lifespans

Female orcas can live up to 50 years, with some individuals reaching over 80. Males typically live to around 30 years. Females usually give birth between 15 and 40 years of age.

8. Killer Whales Sleep with One Eye Open

Orcas sleep by shutting down one half of their brain, keeping the other half awake to control breathing. This allows them to maintain awareness of their surroundings and continue swimming while resting.

9. Offshore Orcas Eat Sharks

Offshore orcas, found in the northeast Pacific Ocean, are known to hunt and eat sharks. These orcas have unique feeding habits compared to other orca populations.

10. Orca Gestation Is Long

Orcas have one of the longest gestation periods in the animal kingdom, lasting 15 to 18 months. Females typically give birth every 3 to 5 years.
