Marine mammals can remember their friends after 20 years apart, study says. Sorry, elephants: Dolphins have taken the top spot for best memory, at least for now.
As humans, we pride ourselves on our impressive brain power, but when it comes to memory, we've got rivals. Squirrels, elephants and dolphins are just three animals with amazing memory capabilities.
A comparable study on chimpanzees found that bees had the worst memory, with a recall duration of just 2.5 seconds. Also earning bees a spot on the list of top 10 animals with the worst memory in the world.
Cuttlefish, an octopus relative, retain their cognitive powers as they grow older. Even in old age, cuttlefish remain as mentally sharp as ever. Ageing mammals — especially humans — gradually lose their ability to remember specific events.
The great apes are considered to be the smartest creatures after humans. Among them, orangutans stand out as being especially gifted with brain.
Chimpanzees
This research has firmly established that chimps are one of the most intelligent species on earth.
It's a common saying that elephants never forget. But the more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative, and benevolent creatures on Earth.
Animals that don't need sleep (bullfrogs and dolphins) Animals that don't need rebound sleep after using up all their energy (bees) Animals that show harmful side effects from sleep deprivation (humans)
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.
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.
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.
#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.
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.
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.
Jellyfish have no brains at all, so they do not even have an IQ.
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.
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!
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.
Chimpanzees now have to share the distinction of being our closest living relative in the animal kingdom. An international team of researchers has sequenced the genome of the bonobo for the first time, confirming that it shares the same percentage of its DNA with us as chimps do.
Dogs really are one of the best animals for humans. Loyal and sensitive to human emotions, dogs have gotten along with people throughout history.
Beavers, horses and dogs are all animals renowned for their diligence.
