World Octopus Day – October 8, 2022

World Octopus Day is annually marked on October 8 and we are drawing up plans to celebrate the existence of one of nature’s most iconic sea creatures. Octopuses are remarkably intelligent and adaptable. With some Octopus fossils predating the era of dinosaurs, they are known to be older than most creatures currently existing today. One thing you can be sure of is that there’s more to this amazing sea creature than a bulbous head and eight legs with suction cups.

History of World Octopus Day

Octopuses are members of the class Cephalopoda, which means ‘head foot’ in Greek, while the name ‘octopus’ comes from the Greek word ‘októpus,’ meaning ‘eight foot.’ Octopuses have eight arms, which more often than not have suction cups at the bottom. The arms have clusters of neurons in them, which allow different arms to do different tasks at the same time. These neuron clusters may be considered to be brains. Thus, octopuses have nine brains, having a central one that controls their nervous system and one in each arm.

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. They are highly intelligent and have been known to perform tasks ranging from opening jars to using tools. They are incredibly flexible, are great at hiding, and can be found in every ocean in the world.

In addition, octopuses are visually stunning, coming in various colors, a multitude of sizes, and all sorts of shapes. Some live in the very shallow waters of the sea, while others can be found thousands of meters below the surface. Sometimes called the chameleons of the sea, octopuses are often able to change colors to blend in with their surroundings as a form of protection against predators.

According to some sources, World Octopus Day was started in 2006 by “The Octopus News Magazine Online” to celebrate the uniqueness of the octopus. It has been annually observed since then.
