Hi guys! Welcome to my blog! I was reading a National Geographic magazine at school. In the magazine, there was an article about octopuses. It was pretty interesting!

Did you know that there was such thing as a coconut octopus? The name, “coconut octopus” comes from its habit of hiding in empty coconut shells. But he can also hide in any other shell that fits his/her body. A coconut octopus is the size of your thumb! How interesting! Its arms are about three times as long as its body. It can also camouflage to the ocean sand. It can squirt water from under its head. You can see, a coconut octopus is very protective!

The ink sac is an octopus that is 10 inches long and lived long ago. Their arms are loosely grouped together. Each arm is marked with rows of circles. This octopus is about 90 million years old. It is one of the oldest known octopuses!

Octopuses have three hearts and get this, they have blue blood! When they’re in danger, they squirt a cloud of ink and jet off in another direction. Their suckers can stick to almost anything! Octopuses have no bones.

Octopuses are cephalopods. Cephalopod is a Greek word that means, “head-foot”.

Octopuses are intelligent animals. They are intelligent because of their nervous system. Cells of the nervous system are called neurons. Neurons carry different messages to the octopuses brains. A human brain has 90 billion neurons! Normal octopuses have 500 million neurons.

Octopuses can camouflage very well. Whenever an octopus sees any predator, they camouflage to the nearest rock or plant that they see. That keeps the octopus very safe! They can change their color, they can change their posture, and the texture of their skin.

Okay guys, remember to comment down below on this article. This might be my last post before the summer, so bye! Have a good summer!
