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.
For years, dolphins have been heralded as the smartest animals on Earth, second only to humans—though some would even contest that ranking. Aside from humans, dolphins have the greatest brain-to-body ratio among animal species, including primates.
We all know Dolphins are intelligent, in fact Dolphins are listed as the animal third in intelligence, after pigs and chimpanzees.
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!
Pigs have the intelligence of a human toddler and are ranked as the fifth most intelligent animal in the world! In fact, pigs are more intelligent and trainable than any breed of dog. They learn their names in just two weeks and come when they're called.
Koalas. Koalas are not only extremely cute, they're smart, too! The marsupials know how to listen to their bodies and can dive into a deep sleep for an average of 22 hours a day. Koalas snack on eucalyptus leaves, which aren't high in nutrients—the abundant rest makes this diet possible.
Did you know that pigs are considered the 4th most intelligent animal (after chimpanzees, dolphins and elephants).
These animals have been described in the Guinness Book of Records as the "most fearless animal in the world" A pair of honey badgers take on a pride of lions. It is not for nothing that the honey badger has earned the reputation of being the most fearless animal in the world.
1. Border collie. According to The Intelligence of Dogs, which ranks 131 dog breeds in terms of their relative intelligence, the border collie is the smartest dog breed known to man.
Not only did the researchers discover that koalas are cleverer than first thought, but that these experimental structures are working to keep them safe.
Rats are as smart as dogs
According to PETA (People for the Ethical Treatment of Animals), rats are: “Natural students who excel at learning and understanding concepts. Rats are considerably smaller than dogs, but they are at least as capable of thinking about things and figuring them out as dogs are.
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.
They learn faster than dogs or primates and their intelligence is compared to that of a three year old child. Cows have excellent problem solving skills that involve logic. Once they master how to solve a problem, they celebrate jumping, wagging their tails and running happily.
Scientists have studied both species and their brains to find the answer to this very question. And, scientifically speaking, dogs are likely smarter than cats. The research study looked at the brains of animals in the order Carnivora, a group of mammals containing bears, seals, raccoons as well as cats and dogs.
7. African Gray Parrots. African Gray Parrots are thought to be one of the most intelligent species on the planet, rivaling even apes. Some researchers have suggested that these parrots have a reasoning ability akin to a three- or four-year-old human child.
Dogs, alas, are not on the list. 1. Octopuses are by far the world's smartest invertebrates; they carry out complex tasks like opening a jar, have excellent long-term memory, and an astonishing ability to learn new skills from the moment they are born.
Zookeepers and animal trainers consider bears to be smarter than dogs. The bear's cunning is legendary when it comes to guarding itself against danger from hunters and poachers. The animal's uncanny ability to evade human predators during hunting season could almost be considered forethought.
koala. Koalas are known for their laziness and sleeping abilities, spending only two to six hours awake every day. Their diet is to blame for their sleepiness though.
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 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.
