Don't Assume Fish Are Stupid: This Fishing Method Will Crush Your IQ
Throughout history, we've mistakenly believed fish are simple-minded and have little intelligence.
It's even been falsely claimed that fish memory is limited to only 7 seconds, after which they forget – this is simply a myth.
Although fish brains are small and have a relatively small brain capacity, fish have existed on Earth for a much longer time compared to humans.
If fish were truly stupid and didn't know anything, they would have been eliminated long ago.
Fish not only have memory and intelligence, but also a strong learning ability and the ability to mimic.
Some fish can even use simple tools or employ their hunting skills to catch their favorite foods.
For example: 'Piranha,' the piranha is a fish species primarily found in South Asia.
Its name itself suggests teeth, and a not-so-small number of them, otherwise why is it called a 'piranha'?
This is the entire appearance of the piranha, its plump body, and long teeth – it looks quite fierce. This fish is indeed very ferocious.
Piranhas generally live in coral reefs, and their food consists of shellfish. How do fish manage to eat such hard shellfish?
This begins with the search for food. Beneath coral reefs, there are various shellfish, but eating them is not easy.
When some shellfish are difficult to reach, they use their 4 teeth to move the coral covering the shellfish, effectively capturing their food.
The shells are very hard, and it's impossible to bite them open directly; they can only smash them open with stones. The piranha bites the shellfish and then violently slams it against a stone – one, two, … until the shellfish is crushed, then they can enjoy their meal. This operation is not limited to individual piranhas, but is practiced by the entire piranha species.
Shellfish are their primary food source.
In fact, all fish species have intelligence, it's just that the level of intelligence varies. Even the same fish species can have different levels of intelligence depending on their environment.
Wild fish versus farmed fish have a much greater difference. Farmed fish have no worries and eat all the time, and their intelligence will not improve.
Wild fish constantly strive for survival and adapt to their environment, and their intelligence is constantly increasing.
What are your thoughts after watching the piranha's hunting method? How intelligent do you think it is? Guang thought that fish's IQ should be at least over 80. Below is an IQ chart.
