Scientists think that many fish are smarter than we think. They have shown that they are able to process information. The fish were trained to associate the name of a familiar fish with a different fish, such as a bluefin tuna or a red snapper. Once trained, the fish learned that the familiar name was the same as the new fish’s name, regardless of whether it was familiar or unfamiliar to them.
They were also able to discriminate between familiar and unfamiliar fish by looking at the colour of their eyes and their body shape, as well as their size and shape of fins and gills. This is the first time that a fish has been shown to be capable of learning and recognising a new species.

What are fish’s IQ?
When a freshwater salmon has an IQ of 100, its IQ is not very high. The average IQ in the U.S. is about 100, which means that the average American has about a 50% chance of being the smartest person on the planet. That’s a pretty low chance, but it’s still a lot better than the chance that you’ll be the dumbest person in your family.
Do fish remember you?
The fish can tell a human face from dozens of other faces. The study, published in the Journal of Experimental Biology, found that the animals were able to recognize the faces of their own species, as well as those of other fish species they had never seen before.
What is the IQ of a cat?
The Bengal tiger (Panthera tigris sumatrensis), the largest of the tigers in Java, Sumatra, and Borneo, has a brain size of 2.5–2.9 m.
The largest living carnivore is the great white shark (Carcharodon carcharias), with a body length of up to 1.6 m and a maximum recorded weight of 1,500 kg.
It has been estimated that the shark has a lifespan of about 30 years, although it is not known how long it can live without food.
What is the IQ of a dog?
The average dog has an iq around 100. The results of a dog’s IQ test showed that the dog’s IQ is the same as a human’s. Some breeds are more expensive than others. For example, a Labrador Retriever can be as much as $200, while a Pomeranian costs less than $50.
Can fish cry?
It is often thought that fish may lack the limbic system, but in reality, fishes do have a limbic system, but they don’t have the emotional system.” The study was published in the Journal of Comparative Neurology.
Do fishes fart?
Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart. Sand tiger sharks excrete out the back door of the water when they gulp air into their stomachs at the surface. In the case of a shark, it is not uncommon for it to have a gill-like structure that is used to expel air from its stomach.
This is known as a “gill plug” and is found in many species of sharks including the great white shark (Carcharodon carcharias) and hammerhead sharks (Megaptera novaeangliae). It is thought that this is a way for the shark to get rid of excess water that has built up in the stomach due to a lack of food.
