How Many Brains Does an Octopus Have? The Wonderful Design of This Sea Creature

When you think of an alien, what comes to mind?

The ocean is home to many creatures that seem almost alien, and one of the most fascinating is the octopus. With its large head, wavy arms, and incredible intelligence, the octopus is often called the “alien of the sea.”

Let’s dive into the incredible design of octopuses and answer the big question: How many brains does an octopus have? We’ll also take a look at how they’re born, how they use ink as a defense, and even what the Bible has to say about why believers are sometimes called “aliens” in this world.

What Exactly Is an Octopus?

Octopuses belong to a group of animals called cephalopods, which also includes squid, cuttlefish, and the nautilus. They’re actually a type of mollusk, just like snails and clams—but unlike mollusks with hard shells, octopuses have soft, squishy bodies that can squeeze into the tiniest spaces.

There are about 300 different species of octopuses, and more species are still being discovered. Their ability to change color, fit through incredibly small openings, and even use tools shows just how brilliantly God designed them to survive in the ocean.

How Is an Octopus Born?

Octopus moms lay eggs just once in their lifetime. Depending on the species, they can lay tens of thousands of eggs, each one no bigger than a grain of rice. The mother spends about six months caring for her eggs. She keeps them clean with her siphon. (Which is like a jet.)

But here’s the sad part: once the eggs hatch, the mother’s job is done, and she dies shortly after. She gives everything to protect her babies, ensuring they have the best chance of survival in the vast ocean.

How Many Brains Does an Octopus Have?

Now for the big question—does an octopus really have nine brains? Yes! But not in the way you might think.

1. One Central Brain – This is the octopus’s main brain, controlling its overall functions. And here’s something wild—it’s donut-shaped and actually wraps around the octopus’s esophagus!
2. Eight Arm Brains – Each of the octopus’s arms has its own mini-brain, called ganglia. This means the arms can move, react, and even make decisions on their own, without waiting for instructions from the central brain.

Because of this unique setup, octopuses can do some pretty mind-blowing things, like opening jars, solving puzzles, and even escaping from tanks.

How Does an Octopus Shoot Out Ink?

One of the coolest tricks in an octopus’s defense toolbox is its ability to squirt out a cloud of dark ink when it feels threatened. This ink comes from a special organ called the ink sac and contains melanin—the same pigment that gives color to human skin, hair, and eyes.

Some octopuses can even create a fake shape out of ink, called a pseudomorph. This blob of ink looks like the octopus itself, tricking predators into attacking the wrong thing while the real octopus makes its escape.

Why Does the Bible Say We Are Like Aliens?

Octopuses might look like aliens, but they are simply part of God’s amazing creation. However, did you know the Bible actually calls us aliens?

In 1 Peter 2:11, believers are referred to as “foreigners and strangers in this world.” Some translations use the word “aliens.” That doesn’t mean we’re from another planet! It’s a reminder that this world isn’t our final home—we were created for something more, something eternal.

The next verse says:

“People who do not believe are living all around you and might say that you are doing wrong. Live such good lives that they will see the good things you do and will give glory to God on the day when Christ comes again.” — 1 Peter 2:12

Just like an octopus stands out with its incredible abilities, believers are called to stand out—not by looking different, but by living in a way that points to God.

God’s creativity is on full display in the octopus, from its nine brains to its incredible escape skills. Learning about creatures like this helps us see just how amazing His designs are!
