9 brains, 3 hearts. Surprise event. This strange body structure of the octopus has surprised the biology researchers. They have studied the function of so many brains and hearts of octopuses. Scientists thought that octopuses might be very intelligent creatures because of their multiple heads. He doesn’t care if he has a heart attack because he has more than one heart? Or if a heart is useless, he lives forever with the rest! This raised questions in the minds of scientists. According to the research, 8 out of these 9 brains of the octopus control the trunk in its body. These 8 brains can send instructions to each trunk to move separately. Again they can work together to capture an object or prey.
He has to manage the rest of the body with the remaining 1 brain. It is known that the female octopus in the Pacific Ocean has 280 suckers in 8 arms. However, male octopuses have very few suckers on their arms. Two of the three hearts of the octopus pump the blood and essential proteins in the body to the lungs, where the blood is mixed with oxygen. The third heart pumps that oxygenated blood and proteins to the various cells throughout the body. Then the blood is drawn again by the two hearts and sent to the fulcrum. In this way, the blood in the body of the octopus starts to flow cyclically.
Octopus blood also has special properties. Their blood color is not red. Blood contains copper-rich hemocyanin instead of iron-containing hemoglobin. And this is why the color of blood is blue.
According to marine animal researchers, octopus blood contains high quality hemocyanin to maintain oxygen supply in cold ocean environment. However, the octopus can adapt to the relatively warm water of the sea. They adapt to the environment by increasing the blood circulation in the body in warm water.
According to biologists, there are more than 300 species of octopus in the world.
Octopus has more specialties. Like a chameleon, it has a special system in its body to blend in with the environment. In fact, in the skin of various arthropods or cephalopods, including octopuses and squids, the chromatophore cells contain sacs called cytoelastics. This sac is filled with yellow, brown or black pigment particles. These sacs can contract and dilate. When the muscles around the sac contract, the pigment sacs are pushed out. These dye particles are then visible. At that time their trunk color changes. They can change their body color in the blink of an eye. Each chromatophore cell is connected to a nerve. That is why the contraction and expansion of cells is controlled by the nervous system.
When the octopus senses a predator, the chromatophore signals the brain to change color. A sudden change in body color stuns the enemy. Blends itself into the environment in such a way that it becomes difficult to detect easily.
Again, they have a type of gland in their body from which black colored toxic ink is released. That ink accumulates in a sac in the body. In case of danger or to fool the enemy, they mix that poisonous ink in the water. As the ink spreads, the water becomes murky. At that opportunity, the octopus immediately ran away.
