13 reasons why octopuses are my favorite animal.

They are very smart.

They can open jars, solve puzzles, use tools, and learn from other octopuses by watching them. Some octopuses will play with toys.

They have eight arms!

Yeah, you already knew this, but just think about it. So cool.

Their arms are covered with hundreds of suction cups.

They have three hearts.

One for each gill, and one to pump blood (which is blue because it is copper based not iron based like our blood) to the rest of the body.

The male literally hands the female his sperm in order to mate.

They can be big...

or small.

They are great hunters

They kill their prey by injecting it with paralyzing saliva and then chew it up with their beak.

They get around by shooting water jets out of their head, or by crawling.

They can even get around on land for short periods of time.

They can squeeze into really tight spaces.

The only hard part of their body is their beak, and the rest is all squishy.

They have incredible camouflage.

Not only can they change their color, but their shape and texture as well.

As a last resort, they shoot ink in your face.

The ink, in addition to being impossible to see through, will sting the eyes, and affect the sense of smell of the predator.

They are beautiful badass motherfuckers.

This Blue Ringed Octopus has enough venom to kill 26 adult humans within minutes.

P.S. Octopi is NOT the correct plural for octopus. The ending us only converts to i if the word is derived from Latin, and the word octopus is derived from Greek. The correct plural is octopuses.
