It depends on the test, but some say that the average I.Q. of a dolphin is 126. The scientist estimated it's IQ in the 80–90 range.
So, how smart are dolphins? Well, it's believed that dolphins are actually the second smartest animal on the planet, next to humans. And yes, even smarter than primates. With a high brain-to-body weight ratio, dolphins are capable of complex problem solving and understanding abstract situations.
You could suggest by comparison to human subjects that there I.Q. would definitely exceed say 30 but possibly not exceed 80. This would be for a adult captive dolphin who had training and regular human interaction.
Current tests for intelligence indicate that dolphins do not possess the same cognitive abilities as humans and are thus not the "smarter" species.
The encephalization quotient (EQ) (the size of the brain relative to body size) of elephants ranges from 1.13 to 2.36. The average EQ is 2.14 for Asian elephants, and 1.67 for African, with the overall average being 1.88.
Animals don't have a measurable IQ in the same way humans do, as the tests we use to measure intelligence are human-centric. It's more meaningful to study animal intelligence by observing behavior and problem-solving abilities in contexts relevant to the animal's lifestyle and environment.
This is amazing for a monkey as the average I.Q for humans in the world is at 100. Answer and Explanation: A variety of cognitive research on chimpanzees places their estimated IQ between 20 and 25, around the average for a human toddler whose brain is still developing the ability to use various cognitive abilities.
The domestic cat is attributed a value of between 1–1.71; relative to human value, that is 7.44–7.8. The largest brains in the family Felidae are those of the tigers in Java and Bali. It is debated whether there exists a causal relationship between brain size and intelligence in vertebrates.
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.
Orcas are very intelligent. Some researchers have done research on the IQ of humans and killer whales and found that the IQ of Orcas is equivalent to that of fifteen or sixteen-year-old humans.
and psittacines (parrots, macaws, and cockatoos) are often considered the most intelligent birds, and are among the most intelligent animals in general. Pigeons, finches, domestic fowl, and birds of prey have also been common subjects of intelligence studies.
A variety of cognitive research on chimpanzees places their estimated IQ between 20 and 25, around the average for a human toddler whose brain is still developing the ability to use various cognitive abilities. This is not to say that chimpanzees are not intelligent animals.
To calculate IQ, take a person's mental age, divide it by chronological age, then multiply that number by 100. For example, if a person has a mental age of 12 but is 10 years old, then you'd divide 12 by 10, and multiple that number by 100, which would result in an IQ of 120.
Pigs are actually considered the fifth-most intelligent animal in the world—even more intelligent than dogs—and are capable of playing video games with more focus and success than chimps! They also have excellent object-location memory.
According to research, cows are generally quite intelligent animals who can remember things for a long time. Animal behaviorists have found that they interact in socially complex ways, developing friendships over time and sometimes holding grudges against other cows who treat them badly.
The border collie, for instance, is the smartest breed, closely followed by poodles, German shepherds and golden retrievers.
The horse's EQ is 0.9. It's not massive, but it's far from small either. To give that some context, the score for a dog is 1.2 and for a cat it's 1.0. On the other hand, the score for a sheep is 0.8 and a rabbit is all the way down at 0.4.
Cats and dogs are colour blind
However cats and dogs only have blue and green cones. This means they have a much more muted perception of colour, which is akin to colour blindness in humans. As cats and dogs are not sensitive to red light, they have difficulty distinguishing some colours.
There has been extensive studies on the intelligence of fish and other creatures. The average IQ of a goldfish ranges between 30 to 40 according to research. Although this is not nearly intelligent enough in the human spectrum, this value is way ahead for aquatic life.
What is the IQ of an octopus? - Quora. If we could turn all the animals into humans to take the IQ test, octopuses would outscore most humans on the math portion at a genuis level of above 140. They would also do very very well at spatial visual. However most of the other fields they would be very low.
There's no record of the lowest IQ ever. However, the lowest IQ score possible is zero.
