Celebrate World Octopus Day

Octopuses have three hearts, nine brains and blue blood. A variety of species can be found in around the globe, we're celebrating this amazing creature with some exciting videos.

As the name suggests, World Octopus Day celebrates one of the most distinctive creatures living on the planet today; the incredible octopus.

Octopuses, or the octopi, are one of earth’s great survivors. Indeed, despite their relatively short lifespan, octopus fossils date back more than 500 million years, meaning that they pre-date even dinosaurs.

The octopus is considered to be one of the most intelligent animals in the ocean. They are inventive, curious, have the ability to learn quickly and are able to solve complex problems.

They are also well known for spraying ink to defend themselves from predators, and for building pretty octopuses' gardens in front of their hideouts on the reef.



All octopuses are poisonous, but only the blue ring octopus in the Indian Ocean could be dangerous to humans.


Two of the octopuses hearts pump blood to their gills, while the third circulates blood to the rest of their bodies. Their nervous systems consists of a central brain and a smaller brainlike nerve cluster for each of the eight arms.

Having no bones in their bodies (apart from a parrot-like beak) they are able to squeeze in and out of even the smallest openings. That's why you might even find an octopus inside an empty bottle!

The octopus is a master of camouflage:
