3 Hearted Sea Creature: Octopus

What do we know about this creature, whose scientific name is Octopoda, which most of us know as octopus, which means "eight feet" in Greek?

How sure are we of the accuracy of what we know?                         

As the name suggests, it has eight legs. Actually, it would be more correct to say arm. Octopuses from the family of crustacean cephalopods have a soft body. The blue color of their blood is another important feature. The reason their blood is blue is the pigment called hemocyanin. Contrary to our blood, a protein called hemocyanin contains copper, not a specific iron. We can attach these copper atoms to a large number of oxygen atoms. This easily meets the oxygen needs of octopuses. There are three of the hearts we have. It would be harder to meet the oxygen needs of these hearts than ours. There are times when they do not even need the oxygen around, thanks to the oxygen it stores in their blood. In fact, thanks to this protein, most living things can survive at very low temperatures for survival. These creatures, which have about 300 different species, live an average of five years. These creatures, which most of us consider dangerous and aggressive, are actually quite timid creatures. . They won't attack unless they sense any threat. They can defend in many ways at the time of attack. The most common of these is to secrete a liquid and confuse the attacker. Contrary to popular belief, this liquid is not toxic. This fluid they secrete is known as ink fluid. For this reason, octopuses are also considered in the squid class.

So why do we think this liquid is toxic?

 Octopuses also have a toxic side. Their saliva. When hunting, they use this poisonous saliva to paralyze their prey. These creatures, which can also push their enemies away by spraying water, can launch in the opposite direction of the water they spray. They also got the nickname "sea chameleon" because they can change their color. They can communicate with other octopuses by changing color. These creatures, which can be easily camouflaged thanks to this ability, use the camouflage feature both for hunting and for protection from other creatures. The suction cups it uses while hunting adhere to the animal it hunts and prevent it from escaping. They kill with their poisonous saliva and crush their prey with their powerful jaws. Octopuses are quite different from other creatures with their intelligence. They have a complex brain. They are living things that have the capacity to solve problems. Getting out of mazes easily, getting rid of the container in which they are placed, and loosening the knots that are given, proves their intelligence.

So how do these creatures reproduce?

Octopuses provide the continuity of their generation by laying their eggs, which are a sexual breeding species. While female octopuses reach maturity between 16-18 months, male octopuses reach maturity between 8 and 10 months, which is much shorter than females. Female octopuses do not live long after spawning, so the maturity of female octopuses determines their average life span. Like all living things, octopuses look for a safe home for their eggs. And a mother patiently waits for her baby to wake up until the hatchlings hatch. If he is about to starve, he will eat a piece of his arm to meet his nutritional needs.

So what happens when you buy parts from yourself?

The part he broke is usually the arm and the broken arm regenerates itself.

 If we talk about the fossil past of octopuses, they lived in the seas 300 million ago in the carboniferous period.

Let's talk about the size of octopuses.

We can say that the largest octopus ever seen and recorded scientifically weighs 71 kg. There are also claimed to be larger octopuses. Octopus Wolfi is one of the smallest octopus species seen. This type of octopus, smaller than 2.5 cm, is not even 1 kg. Adult octopuses usually weigh around 15 kg. They have 4.3 m arm length.

I think we know more about octopuses now.
