Fish Have Feelings, Too: The Inner Lives Of Our ‘Underwater Cousins’ : The Salt Jonathan Balcombe, author of What A Fish Knows, says that fish have a conscious awareness — or “sentience” — that allows them to experience pain, recognize individual humans and have memory.
Summary: It is popularly believed that fish have a memory span of only 30 seconds. Canadian scientists, however, have demonstrated that this is far from true — in fact, fish can remember context and associations up to 12 days later. It is popularly believed that fish have a memory span of only 30 seconds.
Do fishes feel pain when hooked?
Do fish feel pain when hooked? The wild wriggling and squirming fish do when they’re hooked and pulled from the water during catch-and-release fishing isn’t just an automatic response—it’s a conscious reaction to the pain they feel when a hook pierces their lips, jaws, or body.
There is no way to get conclusive evidence that one fish is the smartest. What is the IQ of a goldfish? Their IQ lies between 30 and 40. If you’re comparing their IQ to conventional standards, it is not very high, especially when a freshwater salmon has an IQ as high as 130.
For fish, that title goes to manta rays. They’re giant, charismatic and basically geniuses. Mantas have huge brains — the biggest of any fish — with especially developed areas for learning, problem solving and communicating.

What is a dolphins IQ?
Humans have the highest EQ at 7.4, but bottlenose dolphins have EQs of 5.3, significantly higher than all other animals.
How much IQ does a dolphin?
In some dolphins, it is less than half that of humans: 0.9% versus 2.1%. However, this comparison is complicated by the large amount of insulating blubber Delphinoidea brains have (15-20% of mass). The encephalization quotient varies widely between species.
What is the IQ of a dog?
The average dog’s IQ is about 100. Based on the results done to test a dog’s IQ, it turned out that dogs, even the average ones, have the IQ same as a 2-years old human.
The great apes are considered the smartest creatures after humans. Of course, humans are biased in this regard, but the intellectual capacity of the great apes is difficult to deny. After all, we share over 96 percent of the same DNA. Orangutans stand out as being especially gifted in the brains department.

What causes IQ to drop?
The cause of the IQ decline is due to environmental factors, and not genetics, said Ole Rogeburg, a senior research fellow at Ragnar Frisch Centre and co-author of the study on IQ scores, published in the Proceedings of the National Academy of Sciences journal.
Researchers have previously shown that a person’s IQ is highly influenced by genetic factors, and have even identified certain genes that play a role. They’ve also shown that performance in school has genetic factors. But it’s been unclear whether the same genes that influence IQ also influence grades and test scores.
What age does IQ peak?
Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline.
Is mental age an IQ?
mental age, intelligence test score, expressed as the chronological age for which a given level of performance is average or typical. An individual’s mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ).
