As humanity, although we have set our eyes on the sky and focused on solving the mysteries of space, there are actually seas and oceans filled with wondrous life forms at our feet. on the world One of the places where the diversity of life is most intense, We are not sure how many species live in the oceans and seas.

so far about 250,000 multicellular sea creatures will be mentioned. However, despite this high number, almost all creatures live in the seas 91% still unknown is being considered. The extraordinary features of some of the sea creatures we know of are ‘who knows how many other creatures we don’t know about, but have incredible features?’ begs the question. One of these creatures octopuses† So, what features did octopuses manage to be so “special”? Let’s take a look together.

3 inches to 9 meters: There are more than 300 kinds of octopus

When it comes to octopus, everyone can have a very different picture. While some of us may imagine a giant octopus, some of us may think of tiny octopuses the size of a finger. The reason is known More than 300 octopuses to be. In addition, the size of octopuses can range from 3 centimeters to 9 meters. An incredible range…

Octopuses build doors, decorate their houses and live alone

We know that octopuses generally live alone and mainly feed on crabs, shrimps and mollusks. Even these strange creatures, carry stones to the entrances of their ‘houses’ and use them as doors Once inside, they close their doors and protect themselves. In addition to creating doors to these private and secret homes, they also create living spaces. ‘decorate’ with shells They also show the behavior.

They have three hearts and their blood is blue

Octopuses have a total of three hearts. of these hearts when someone has the job of pumping blood around the body the other two pump blood through the gills of octopuses. Also, the blood of octopuses with three hearts is not red; in blue color. The reason for this is instead of the iron pigment called hemoglobin in their blood, to a copper pigment called hemocyanin their property.

They can ‘disappear’ in 0.3 seconds and there are very poisonous species

One of the fascinating features of octopuses is their incredible camouflage ability. able to camouflage itself at great speed in 0.3 seconds. Octopuses imitate the color and texture of where they are so well that they almost ‘destroy’ them.

But that’s not the only defense mechanism they’ve developed. At the same time, some octopus species can be deadly poisonous. Blue-rimmed octopuses, one of the most venomous octopuses known, secrete a venom strong enough to kill 26 adults at once. 10,000 times more toxic than cyanide.

They can use tools and distinguish people from each other.

One of the greatest proofs of the impressive intelligence of octopuses is: their ability to use resources. It was even known that the ability to use tools is unique to humans, some species of primates and birds. But octopuses completely change this knowledge.

For example, if there is no place to hide, octopuses can make places for themselves by combining the shells they find around them, they can disassemble the filter systems from a structure that can be quite complex for an invertebrate creature like an aquarium, or they can ‘escape’ by opening the caps of the bottles they are trapped in.

They lay about 50,000 eggs at a time, and mother octopuses ‘eat their arms’ to protect their young

Octopuses don’t live long; It is thought to be between 1 and 5 years on average. There are even octopuses with a lifespan of 6 months. However, in these short lives, female octopuses tens of thousands of puppies to give birth.

We know that an octopus can lay an average of 50,000 eggs at a time. Cracking these eggs about 40 days progress. In this process, mother octopuses must both protect their eggs from danger and “ventilate” them by creating a current on the eggs. Mother octopuses are starving from this hard work he can eat his own arms known. However, this behavior is also seen in captive octopuses; Hence, it is thought to be a stress-based behavior.

It’s not just the number of octopus ‘arms’ that stand out

We know that octopuses have eight arms. However, it is not the number that draws attention to the arms of these creatures. Each octopus arm moves independently of the brain. It can make decisions and continue to react even hours after it has left the brain. In other words, octopuses’ arms can pretend to have their own brains.

In addition, the chemo-sensory cells in their arms allow octopuses to not only touch their arms, but also to touch them. also collects information through tasting† Octopuses can also regenerate their severed arms.

It has been argued that they may indeed be ‘out of this world’

An article published in recent years about octopuses and their fascinating properties caused a lot of controversy. A group of scientists octopuses are out of this world He claimed. Their theory is that an “alien virus” was transported to Earth millions of years ago by a meteorite and “infected” a primitive squid population, allowing them to turn into octopuses.

The reason for this strange claim is: The claim that some points in octopus evolution and gene sequence are full of unknowns† However, after this article was published, almost the entire scientific world rejected these claims. Because octopus gene sequences were deciphered and shared way back in 2015, and many studies have been done to show that the “mysterious” leaps in their evolution are not so mysterious.
