The fish's memory is only 7 seconds, which is obviously a lie, and by no means a beautiful lie, but a cruel lie.
If the fish's memory is really only 7 seconds, then it is a miracle that this creature can survive to this day. People are willing to believe that the memory of a fish is only 7 seconds, because people wish they could also have such a short memory to forget all the pain in life. It is true that the memory is short in some ways a good thing, from a spiritual point of view, short memory does not make people fall into endless suffering, and from the material level, for a creature with only 7 seconds of memory, a small basin represents the whole world, because as long as it is 7 seconds apart, everything is new to it.
Short-term memory has many advantages, and the only disadvantage is that it is not conducive to survival, for creatures with only 7 seconds of memory, the world basically has no space for it to live, so the fish's memory is only 7 seconds, doomed to be a lie.
What are the facts? Facts are very different from lies, in fact, fish not only have long-term memory ability, but also can be called a memory master, whether it is short-term memory or long-term memory, fish are extremely outstanding.
There is a small fish living in the ocean, we call it gobies, there are many kinds of gobies, they may not be considered swimmers, but they are definitely jump masters. The appearance of gobies is obviously different from that of ordinary fish, and their left and right ventral fins can be combined to form a suction cup, which can be well resisted by the impact of large waves when they use this suction cup to adsorb on the reef. So, whenever the tide recedes, we are able to find a lot of gobies in reef pits by the sea. Of course, gobies leave themselves here for a purpose, because after the tide recedes, many small fish and shrimp will be trapped in these reef pits, and these are the best meals for gobies.
Simply absorb yourself in a reef pit to enjoy the natural gifts of food, which is indeed an enviable thing, but the only question is, after the meal, how do the gobies return to the ocean? One word, jump.
Gobies are jumping masters and can jump back to the sea step by step with their excellent bouncing ability, and the whole process of gobies jumping back to the sea is extraordinary. People who live by the sea will find that every leap of the goby is able to jump accurately into another reef pit without falling on the rocks, which is an incredible thing in a reef group with complex terrain. Why? Note that when a goby is in a reef pit, because the pit is sunken downwards, it is impossible to see where the other reef pit is, and since it cannot see the exact location of the other reef pit, how does it jump into it exactly? To get the idea, researchers at the American Museum of Natural History studied it.
At first, the researchers placed the goby in a reef swarm that had already receded tide, and the results showed that the gobies did not have the means to jump accurately into another reef pit.
So the researchers put the goby into a reef group that has not yet receded, and after the low tide, the goby can accurately perform its jumping stunt and jump back into the sea. Obviously, when the tide has not yet faded, the goby remembers the depth and location of all the reef pits in the water, so after the tide recedes, there is no need to look at it, and the goby can also accurately jump into another reef pit with memory and choose the best route back to the sea, which is really beyond the reach of many people.
If the gobies' memories of reef craters are only short-term, it is not particularly unusual, and the experiments have proved that the goby memory time is quite long, and after 40 days, the above experiments are re-performed, and the goby can still jump back to the sea according to the correct route.
Will gobies with strong memory abilities be an example of fish species? Obviously not, a large number of studies and experimental results on fish memory have shown that fish have extraordinary memory abilities.
Take our most common domestic goldfish, researchers have done a memory experiment, the experiment is simply to use different color straws to feed different goldfish, after a period of time, as long as the straw is extended into the water, the goldfish will swim to their own color around the straw and wait, even if the same experiment is carried out after a few months, the goldfish can still accurately find the straw of their own color.
In fact, as long as we have our own fish, we will know that if we feed the fish in the same position in the fish tank every time, then it will not be long before when we feed again, the fish will gather in that position on their own, even if we stop feeding for a few days, the situation will not change. So don't say that the fish's memory is only 7 seconds, the fish are actually memory masters.
