Octopuses are truly incredible.
In fact, the nervous system of the octopus is the most complex and advanced of all invertebrates.
The octopus has 500 million neurons in its brain and very sensitive chemical and tactile receptors. Its unique neural structure gives it a thinking ability that exceeds that of ordinary animals.
Many scientists even believe that octopuses are actually more intelligent than humans. The reason why humans have not discovered the civilization created by octopuses in the sea today is that octopuses themselves are solitary creatures, so individual wisdom has always been difficult to convey.
Because octopuses are intelligent, they have the ability to think long-term that other sea creatures do not have. And he uses tools.
Escape from the aquarium is easy when youis as smart as an octopus. This happened at the National Aquarium of New Zealand in April 2016. An octopus named "inky" made this great escape. At that time,Inge’s aquarium was open in the middle of the evening. It exploited this loophole to crawl out of the aquarium, across the room, to the drainage outlet, then back out to sea after crossing a 50 meter long water pipe. Inkee's success once again proves that octopuses are one of the most intelligent groups of creatures on Earth. Let's take a look at eight octopus behaviors to see how smart they are.
Jennifer Mather, a comparative psychologist at the University of Leybridge in Canada, began studying octopuses in 1972. In 1984, during an encounter in a field near Bermuda, she realized that octopuses could be much smarter than we thought. Mather observed an octopus catching several crabes and bringing them back to its nest to eat. Suddenly the octopus rushed 2 meters away, grabbed a stone with its wrist and returned to the nest. Three more times he built a stone wall in front of the house. He seemed confident in his defense, then fell asleep behind the stone wall.
According to Mather, This example and others demonstrate that octopuses have the ability to think long term and prioritize their actions. “All of this suggests to me that this animal has a plan of what it wants and can come up with a plan,” Mather said. “This is very different from what we think of as stimulus-response models when we study animals.” Mather and his colleagues believe that defensive stone "stone walls" can be considered tools. However, some people disagree with this. They think it may simply be an instinctive behavior of the octopus, rather than the res.result of a calculation. This is the octopus striatum. In 2009, Julian Finn of the Victoria Museum in Melbourne, Australia, and colleagues found strong evidence for tool use in octopus striatums. These spotted octopuses dig up coconut shells that have fallen to the sea floor, rinse them with water and sometimes pile them up., moved 20 meters and then climbed back into a shelter. In the diver's video, the octopus first points the protruding side of the shell downward, then extends its tentacles above the shell, crawling on the seabed in a very comical manner.
Julian Finn points out that although this slow, clumsy and energy-intensive movement makes them more vulnerable to predators, they are willing to accept these risks in exchange for future protection. This is conclusive proof that octopuses can use tools.
