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.
#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.
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.
Did you know that pigs are considered the 4th most intelligent animal (after chimpanzees, dolphins and elephants).
Humans have the highest EQ at 7.4, but bottlenose dolphins have EQs of 5.3, significantly higher than all other animals.
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.
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.
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.
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.
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.
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.
Dogs score higher in perceived intelligence ratings than cows, for example, yet a study in the 1970s demonstrated that in a test cows could navigate a maze as well as dogs, and only slightly less well than children.
They have broad social abilities too, like distinguishing individuals out of a group; communicating with each other through touch, smell, sound, and sight; and learning to pick up on the verbal and nonverbal cues of humans. Researchers have even found that pigs are able to use tools and play video games!
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.
Horses and Dogs are both intelligent animals, but they have different cognitive strengths. Horses excel in areas like navigational intelligence while dogs do better with social intelligence. Neither animal is smarter than the other, that's just what makes them unique!
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.
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!
In fact, on some tests of logic, wolves come out on top. In some experiments conducted in 2009, dogs followed human cues to perform certain tasks—despite evidence that they could see that suggested a different strategy would be smarter. In contrast, wolves made the more logical choice based on their observations.
Human eyes have three types of cones that can identify combinations of red, blue, and green. Dogs possess only two types of cones and can only discern blue and yellow - this limited color perception is called dichromatic vision.
Since a cat's cones are most sensitive to blue and yellow wavelengths of light, they do not see colors like red, orange, or brown. They are similar to people with red-green color blindness—red hues likely appear as the color green to your cat.
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.
Three-toed sloths are some of the slowest and seemingly laziest creatures in the world. Instead of evolving to eat more, they evolved to do less.
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.
Sloths are one of the slowest animals on the face of the earth, but they are also one of the smartest animals.
