World Octopus Day

World Octopus Day is dedicated to celebrating the unique and fascinating features of the octopus – a creature with three hearts, impressive intelligence, and the ability to quickly adapt to their environment by changing colors and textures. This special day was founded in 2006 by The Octopus News Magazine Online and has been celebrated annually ever since.


Fossilized remains of octopuses have been discovered that date back to 300 million years ago, meaning that the octopus is a predecessor of the dinosaurs. There are still many mysteries and unknowns around the octopus, as researchers have yet to unlock the secrets of their impressive survival skills – attributed to their 500 million neurons concentrated in their brain and tentacles. Octopuses are solitary creatures and prefer to live in shallow water or deep depths.

Interesting facts

  • Octopuses have a deadly poison in their blue rings.
  • When bored, octopuses may chew on their own tentacles.
  • They are the most intelligent invertebrates on Earth and have the largest brain in the species.
  • Octopuses produce ink which serves as a protective measure and helps them mask themselves.
  • The smallest species, Octopus wolfi, weighs almost 1 kg.
