How Intelligent Are Octopuses?

Octopuses are the most intelligent species of invertebrates. Their IQs have reached an incomprehensible level. A scientist once did a "mirror experiment" with octopuses, allowing octopuses to look in the mirror and see if they know the image in the mirror is themselves. As a result, the octopus passed the test perfectly. It must be known that even intelligent animals such as dogs and cats could not distinguish themselves in the mirror experiment. It can be seen that the octopus has a high IQ. Their cognition is far beyond human imagination.

1. Octopus can imitate more than a dozen marine animals

The pigment cells in the octopus are very developed, and they can be called "ocean chameleons". They can quickly change the color of their bodies within 2 seconds according to the surrounding environment, and even when they are attacked, they can spray ink 6 times in a row to avoid the enemy.

Not only that, but smart octopuses also simulate various creatures in the ocean. For example, when they hunt, they can disguise themselves as algae, so as to deceive small fish. When encountering natural enemies, they will also disguise themselves as jellyfish to avoid being hunted by predators.

Even sometimes, octopuses will wrap 6 tentacles on their heads, imitating conch shells, and then use 2 tentacles as feet to run fast on the seabed, just like humans, and this way of advancing is faster than their swimming speed. How powerful the octopus's ability to imitate is!

2. Octopuses can use tools proficiently

In addition to the ability to imitate, the learning ability of octopuses is also extremely prominent, because they have two kinds of memory systems, one in the head and the other directly connected to the sucker of the tentacles, so their tentacles can deal with complex problems without going through the brain.

Therefore, octopuses can use many tools with their tentacles. For example, when preying on oysters, octopuses will first find a small stone, then secrete a chemical element that forces the oyster to open, and then use the tentacle to throw the stone before the oyster closes.

The octopus can also use its tentacles to turn on the switches of some appliances. Such as throwing the octopus into a glass bottle and then tightening the bottle cap, then the octopus will use its tentacles to follow the thread to unscrew the cap and run away.

3. Octopuses have "logical" thinking

Many people believe that octopuses have "logical" thinking because octopuses can solve complex problems independently. For example, an octopus in the Munich Aquarium found a 50-meter-long drainage outlet in order to return to his home. Then after many efforts, he succeeded in "escape".

In addition, Columbia University has done an experiment on octopuses, they put 50 octopuses in a tank, let a female staff feed the octopuses, and then sent a male staff to take the food to observe octopus performance.

As a result, half a month later, the male staff member who took the food was frequently attacked by the ink of the octopus, and the water volume was 3 liters. It can be seen that, like mammals, octopuses can distinguish humans, and this is also a sign of high intelligence.

We design Brass Octopus Tentacle Hook inspired by the tangled octopus tentacles. In life, many of our supplies are designed to be boring and without a sense of interesting design. When we see the hooks in the kitchen or other places, they do not attract our eyes. These S-shaped hooks are a simple and friendly solution to save space without drilling holes in beautiful houses and walls, you can hang them on shelves, bars, racks, rods and place them in closets, kitchens, garages, bathrooms, gardens, indoors and outdoors.
