Hey Lykkers! Have you ever wondered just how fascinating orcas (also known as killer whales) really are? These incredible marine creatures are more than just their black and white appearance.

They have some seriously mind-blowing traits that make them stand out in the animal kingdom. So, let's dive into 10 cool facts that will change the way you see orcas!

1. How Do Orcas Sleep?

Orcas sleep in a way that is totally different from humans. While we can fall into deep sleep and breathe automatically, orcas can't. They need to consciously decide when to breathe, which means they can't enter deep sleep like we do. Instead, orcas sleep with one half of their brain at a time! One side of their brain stays alert, and the other gets rest. When one side sleeps, the opposite eye closes. How cool is that? This allows them to stay aware of their surroundings and keep breathing.

2. Orcas Love Group Activities!

Orcas are very social animals and prefer to live in groups. These groups can have as many as 40 orcas! Some groups are permanent, while others come together temporarily. Depending on the group, orcas target different prey and use various hunting tactics. They communicate using sounds or echolocation to stay in touch and work together during hunts. It's a whole teamwork operation!

3. Orcas Are Hunting Experts!

Orcas are one of the smartest animals on the planet, and their hunting skills are amazing. When they hunt fish, they work in teams of about 10 orcas. Some of them break into the fish school and scatter them to make the catch easier. Once the fish are disoriented, the rest of the orcas swim around them to push them toward the surface. Then, with their powerful bodies, orcas create waves to stun the fish. And they even have a cool trick—sometimes they use icebergs in Antarctica as natural refrigerators to store their food!

4. Orcas Have a Long Pregnancy

Orcas have a much longer pregnancy than humans. They carry their babies for about 17 months! After birth, orca calves depend on their mother's milk for about two years before they start eating solid food. However, even when they start eating, they typically stay with their pods, learning survival skills from the adults. Orcas are known for passing down knowledge through generations.

5. Orcas Love a Good Massage

Did you know that orcas give themselves massages? It might sound strange, but northern orca pods enjoy rolling around on smooth rocks in shallow waters to give themselves a good rubdown. They release air from their lungs, sink to the bottom, and then roll around for minutes or even hours. Some orcas do this multiple times a day!

6. Orcas Don't Have a Sense of Smell

Interestingly, orcas don't have a sense of smell. Unlike sharks, which use their keen sense of smell to track prey, orcas rely on their sharp hearing. They use echolocation to detect animals around them by emitting high-pitched sounds. These sounds bounce off objects and return as echoes, allowing the orca to "see" its surroundings. They can even hear their prey from over 800 meters away!

7. The Size of an Orca's Brain

Orcas are not just huge animals, but they also have the second-largest brain on Earth, right after toothed whales. Their brains weigh an impressive 7 kilograms, which is much bigger than a human brain. However, don't be fooled—while orcas have big brains, their cerebral cortex, the area responsible for thinking and awareness, is thinner than humans and other primates. So, while they are smart, they aren't quite as brainy as us!

8. Orcas Have Huge Teeth

If you've ever seen an orca's teeth, you know they're massive! They have between 40 and 56 teeth, and each one can grow up to 10 cm long—about the size of a tiger's canine. Although they don't chew their food, they use their sharp teeth to tear their prey apart before swallowing it. Their teeth wear down over time, so older orcas prefer eating fish, which is easier to tear apart.

9. Orcas Only Eat Whale Tongues

When orcas hunt gray whales, they don't go for the tough meat or fat—they target the tongue! The tongue of a gray whale weighs several tons, so a group of orcas can feed on it and be satisfied for a while. Gray whale skin and fat are too tough for orcas to handle with their teeth, so they focus on the softer, more tender tongue instead. Talk about a specialized diet!

10. Orcas Are Fearless Hunters of Great White Sharks

Great white sharks are some of the most feared predators in the ocean. But did you know that orcas have no fear of them? Orcas are known to hunt and eat great white sharks! They use a clever tactic: flipping the sharks onto their backs, which sends them into a state called tonic immobility, similar to a temporary paralysis. Once the shark is immobilized, orcas can easily remove the shark's liver, a delicacy for them!

Wrapping Up: How Much Did You Know About Orcas?

Lykkers, what do you think? Orcas are definitely not just another fish in the sea—they are complex, intelligent, and fascinating animals.
