CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
Dolphins are often cited as the second smartest animals on Earth due to their relatively high brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the dumb apes who research them.
Chimpanzees. As our closest living relatives, chimpanzees have unsurprisingly shown themselves to be exceptionally intelligent. They also have impressive short-term memories – better than our own. Chimps can remember the location of numbers flashed before them for a fraction of a second.
Humans have the highest EQ at 7.4, but bottlenose dolphins have EQs of 5.3, significantly higher than all other animals.
There are several possible answers to this question as different animals display varying levels of intelligence. However, some experts suggest that the animal with the lowest IQ is the sloth.
Cats have a 200 times stronger memory than dogs and can recall the details of a day for up to 16 hours. Although dogs may be better at helping people, cats have much more sophisticated brains. Dogs only have 160 neurons in their brains compared to cats' 300 neurons, making them one of the smartest animals in the World.
Though this data might seem to suggest that dogs are twice as intelligent as cats, a direct correlation between larger brain size and increased intelligence has not been conclusively proven. Regardless, dogs' higher neuron count is often viewed as a gauge of their superior intelligence.
A study from the University of Sydney and the University of Roehampton in London suggests that kangaroos are capable of intentionally communicating with humans, suggesting a higher level of cognitive function than previously thought.
First up, unsurprisingly, is cetaceans - or for the purpose of this article, dolphins and whales. These creatures are supremely intelligent, with some scientists arguing that they are the most intelligent creatures on our planet.
Results showed that the dogs, having larger brains to begin with, had more than twice as many neurons in their cerebral cortex as the domestic cat, with around 530 million cortical neurons to the cat's 250 million. (For comparison, there are billions of neurons in the human brain.)
Some researchers say pigs are even smarter than 3-year-old human children! Pet pigs can learn lots of circus tricks. They can learn how to find food using a mirror and even how to play video games using a joystick! Check out this video of a pet pig performing tricks!
According to several behavioral measures, Coren says dogs' mental abilities are close to a human child age 2 to 2.5 years. The intelligence of various types of dogs does differ and the dog's breed determines some of these differences, Coren says.
Rat Fact - The average IQ of a rat is 105.
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.
Based on the number of neurons found, they speculated that dogs have roughly the same intelligence as raccoons and lions, while domestic cats have comparable intelligence to bears. For comparison, humans have by far the highest number of neurons in our cerebral cortexes—as many as 16 billion per person.
Pigs are gentle creatures with surprising intelligence. Studies have found they're smarter than dogs and even 3-year-old children! In the wild, pigs form small groups that typically include a few sows and their piglets.
Pigs are widely considered to be more intelligent than dogs and equally as intelligent as chimpanzees. They share the ability to perform a number of cognitive tasks with other highly intelligent animals such as dolphins and elephants.
#3: Chimpanzees
Chimpanzees are very smart animals and are able to solve many different problems posed to them by human trainers and experimenters. Our closest genetic relative comes in third place on this list of the most intelligent animals.
Even the dog owners out there, you betrayed your best friend? Well yes, chimps have way more brainpower than dogs. They can use sign language, drive cars and perform complex tasks.
Cows are so much smarter than we give them credit for. They are excellent problem solvers, they remember faces (so make sure you're nice when you meet one!) and they get excited when they find solutions to intellectual problems, just like humans!
Jellyfish have no brains at all, so they do not even have an IQ.
There is no zero point for IQ. We do not think of a person as having no intelligence (although we may be tempted to make that evaluation upon occasion).
IQ is only a measure of human intelligence and cannot be used on snails. Snails are not sentient and only act and react based on instinct and stimulus. They are mollusks lack higher thought function seen in most mammals and birds.
