WORLD OCTOPUS DAY



Nine brains and three hearts. Also more than 250 milion years old and still among us. On October 8th, World Octopus Day celebrates one of the earth’s most fantastic creatures. Sometimes called chameleons of the oceans, they're able to change colors to blend in with their surroundings as a form of protection against predators or also release their ink to get advantage. While it is said that only aristocrats have blue blood, among octopuses it is really true.


  • If an octopus loses an arm, it has the ability to grow it back.

  • Octopuses have not just one, but three hearts! Two for moving blood to the gills and the other for pumping blood through the rest of the body.

  • The giant Pacific octopus is the largest species of octopus in the world.




Octopuses are the third most intelligent animal on earth, after humans and dolphins, and the most intelligent of all the invertebrates.

They use tools, carry their shelters around for when they need them, and some species even hunt with weapons. They can learn to navigate mazes and open jars containing tasty crabs. An octopus has one central brain and then another brain (called a ganglion) at the base of each tentacle to control movement separetely and do different tasks at the same time.


  • The male octopus dies after mating because it has used up all of its body’s energy.

  • Octopuses have blue blood due to the presence of copper in the protein hemocyanin, which carries oxygen around their body.

  • There are over 300 known species of octopus in the world.

  • The Blue-ringed Octopus is one of the deadliest creatures in the world, and can stop your breathing in 30 minutes if you don’t get medical attention.
