A, octopus IQ is very high
Octopus IQ is very high. Octopus brain has 500 million neurons, the body has a very sensitive chemical and tactile receptors, this unique neural structure has the ability to think beyond ordinary animals. Through genetic decoding, scientists found that octopuses have a set of genes similar to humans, which allows them to build neural networks, which explains why octopuses have the ability to learn. Octopuses, like humans, have a not-so-small brain, a closed circulatory system, and eyes with irises, retinas and crystals.
Two, octopus high IQ performance
1, many years engaged in octopus research experts Jim pointed out that the octopus has conceptual thinking, it can solve complex problems alone. It is this ability to make it has the ability to walk on two feet. Octopus in order to avoid the hunter's kill, in addition to the use of mimetic camouflage we are familiar with, shedding wrists to protect the body, U.S. scientists have also found that in the Indian Ocean waters using two-footed walking to escape the high IQ octopus.
2, the U.S. University of California, Berkeley, Christine and its research team in the tropical waters of Indonesia photographed a kind of octopus called Maginnettes, the volume of about the size of an apple, in the face of danger and divers, this octopus will be eight claws in six upward bending fold, and the remaining two claws will be stood on the seabed of the ground, sneakily move backward, like will move the small coconut. /3, another walnut-sized ekulites octopus also walks on two feet, with the other six legs stretched outward to mimic the appearance of seaweed. The team found that the bimanual foot walks much faster than the octopod, with the former's fastest speed being about 0.14 meters per second.
Three, octopus IQ test experiments
1, scientists had a McPhee's octopus intelligence test, the purpose is to make clear whether the octopus can form a stable conditioned reflex. McPhee was busy building a new home, and it picked up a lot of broken glass and stones that people threw to make a defense fence. The building work was done at night, and by morning the transparent house was completed. Behind the crystal wall where thousands of shards of reflector had been piled up, McPhee sat tall and, from all indications, pleased with her masterpiece.
2. So, the octopus doesn't know that glass is transparent, and chooses its material by touch; hard will do. This is instinctive, and not due to the wisdom of the octopus to drag the broken glass into the nest. Obviously, a habitat built of glass trying to hide the eyes of the curious is no better than a king's new clothes covering his body can be.
3. After starving Mr. McPhee for a few days, the next experiment was begun by removing the glass cylinder containing the crab and placing it in the crystal palace where the octopus lived. Greedy eyes were seen staring at their prey for a split second, and wristed hands reached out from behind a wall of pointed glass, then suddenly closed and flopped against the glass cylinder. Though close at hand, the glass separates it, preventing it from reaching its goal.
4. McPhee squirmed, in vain, to catch the crabs that were salivating and close at hand. The skin color keeps changing due to anger. It is impossible to tell, as long as you climb 30 centimeters up the glass cylinder, you can smoothly enter the crab's hiding place through the upper mouth. However, McPhail's greedy eyes could not leave his prey. Based on the rule of a straight line between two points, he stubbornly attacks the crab.
5. The futile attack continued for a long time, and by chance a wristed hand reached the edge of the glass cylinder and the tip of the wristed hand entered the cylinder. At this point, McFelton immediately changed tactics, tying the wrist hand to the glass cylinder, stretching toward the crab, and the whole body also climbed upward. The moment the wrist hand touched the crab, it suddenly contracted back, followed by McPhail entering the tube like a rocket and dragging the crab with it. It appeared as if the tip of the wrist hand had picked up on the crab's scent, causing the blind man to lead the way for the bright one.
6. Of course, by this time, McPhail knew perfectly well how to get the crab through the glass, once and for all, so that the octopus could form a conditioned reflex in its brain center. But unfortunately, it could not learn its lesson, overcome the unnecessary circumlocution, and correctly repeat the first full process of rushing to the glass cylinder, grabbing the crab through the glass, and entering through the upper opening along with the wrist.
7. Under the same conditions, the octopus has a much higher IQ than the squid. Scientists in an experiment on a squid, put shrimp in the glass jar without a lid, but the squid hit the glass jar with its head continuously for 30 hours, and did not want to take a roundabout strategy. A few days later, after McPhail had produced a performance that those ten-handed inbreds could hardly comprehend with flying colors, a more complicated experiment was conducted, covering the cylinder containing the crab with glass, but the wrasses, who had already done some research on routes, overcame this obstacle.
8. After several unsuccessful attempts, the wristed hand finally found a small gap between the bottle and the glass lid, opened the lid, and with it the octopus burrowed in. After a seven-day pause, the original experiment was repeated, with McPhee still mastering the correct method he had learned a week earlier. But the squid's method of finding food through the glass was all but forgotten after 18 hours. Apparently, in the family of cephalopod software animals, the intelligence of each member varies, and nature has endowed the octopus with the strongest ability.
