Which Animals Have Two Brains?

When I’m having trouble trying to figure out a problem, and I just can’t wrap my brain around the solution, I think of the old saying, “Two heads are better than one.” Well, what about two brains? Did you know that some animals, including humans, have two or more brains?

I know, it sounds like science fiction or maybe even a horror movie, ”The Human with Two Brains.” But, it’s true. You probably think I’m crazy, but let’s get into a few examples of animals with two brains.

These incredible and complex creatures are all around us. Not only do humans have two brains, but many other animals do too. You’ll soon find out that I haven’t lost my mind.

Octopus (Octopoda)

According to Scientific American, octopuses and their close relatives, ten-armed squid and cuttlefish, stand apart from all invertebrates. They are ”deep-sea thinkers.” Octopus brains let them remember things, recognize other sea creatures, and explore objects.

Even though they’re invertebrates, their brains act similar to our own. That’s where the similarities to vertebrates end. These Cephalopods have brains that aren’t only in their heads but in their eight arms.

So, octopuses actually have nine brains. Each arm has a unique set of neurons that act independently from each other. Each arm can taste, touch and control feelings using hundreds of sensors.

In fact, the Smithsonian Institute says that octopuses can finish puzzles, open jars and untie knots with their arms. They are masters at ambushing their prey, which are fish, jellyfish and crustaceans. The 300 different species of octopus live in all the oceans of the world.

Humans (Homo sapien)

People have two organs that think for them. Both of these are made up of the same types of neurons and tissue. One is the brain in your head and the other is in your digestive system. They each control different functions in your body.

Your guts and brain are connected, so when you feel anxiety, it disrupts your digestion. Have you ever had to give a speech or walk into a room of new people, and … Read the rest of the story.
