The new research shows that dolphins have the longest memory yet known in any species other than people. Elephants and chimpanzees are thought to have similar abilities, but they haven't yet been tested, said study author Jason Bruck, an animal behaviorist at the University of Chicago.
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.
Chimpanzees and bottlenose dolphins are few among the many animals with good memory and high intelligence.
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.
This rare condition also known as highly superior autobiographical memory (HSAM) causes people to remember just about everything that has occurred in their life. This includes every conversation and emotion ever experienced as well as every person encountered, regardless of how insignificant or minute.
Because the olfactory bulb and cortex are so close physically to the hippocampus and amygdala (huge factors in memory retention), smell is considered the strongest and quickest memory inducer.
As a number, a “petabyte” means 1024 terabytes or a million gigabytes, so the average adult human brain has the ability to store the equivalent of 2.5 million gigabytes digital memory.
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.
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.
Unsurprisingly, chimpanzees are one of the most intelligent animals on this planet—next to humans, of course. Similar to how humans inherit their intelligence from their mother, a chimpanzee's intelligence also greatly relies on their genes.
Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
Hyperthymesia is also known as highly superior autobiographical memory (HSAM). According to a 2017 study , people with hyperthymesia can accurately and readily recall numerous details about events that have occurred in their life.
Hyperthymesia or Highly Superior Autobiographical memory describes people with a formidable ability to accurately recall past experiences and the associated details. When something happened, who was there, what they were wearing, and so on.
Semantic processing is the deepest level of processing according to this model. In semantic processing, additional meaning and related information is encoded at the same time. This leads to a very strong memory trace because of deep processing.
Memories: from birth to adolescence
Adults rarely remember events from before the age of three, and have patchy memories when it comes to things that happened to them between the ages of three and seven. It's a phenomenon known as 'infantile amnesia'.
It is generally accepted that no-one can recall their birth. Most people generally do not remember anything before the age of three, although some theorists (e.g. Usher and Neisser, 1993) argue that adults can remember important events - such as the birth of a sibling - when they occurred as early as the age of two.
However, the study from researchers at City, University of London, the University of Bradford, and Nottingham Trent University found that 38.6% of 6,641 participants claimed to have memories from age 2 or younger, with 893 people claiming memories from age 1 or younger.
#1 Dogs. First on our list of the top 10 friendliest animals in the world is man's best friend – dogs.
According to the Independent, honey badgers have been described in the Guinness Book of Records as the "most fearless animal in the world" and can even fight off much larger predators like lions and hyenas.
#2: Bottlenose Dolphins
Many people believe that the bottlenose dolphin is the smartest animal, but it's ranked number two on this list.
