The shortest memory. Who has the shortest memory in the world?
Metabolism, the ratio of body weight to brain, and many other factors affect life expectancy different organisms. Some animals live more than a hundred years, such as bowhead whales and moray eels. At the same time, the life of some creatures is limited to a few hours. Here is the list shortest living animals organisms in the world.
10. Domestic rabbits. They live 8-12 years.
These small mammals live in various parts Sveta. In domestic rabbits average duration life is approximately 8-12 years. They come in various sizes and colors. But most beautiful representatives this type is often the most short life. The main reasons affecting the health of domestic rabbits are intestinal cancer and obesity. Females suffer from these ailments more often than males. And without timely medical care they may die much earlier. Improper diet, overfeeding with vegetables and juicy fruits, main reason ailments of rabbits. They need fresh water every day sufficient quantity. Rabbits are highly fertile due to their short lifespan.
9. Guinea pigs. They live 4-8 years.
This rodent is cute a pet from South Africa. But their life is limited to about four years. They are often susceptible to diseases. The main requirement for their maintenance is a feeding regimen and constant timely examination by a veterinarian. And here proper care can prolong the life of pets as much as possible. But sometimes it seems quite difficult to save guinea pigs from diseases such as bronchitis or scurvy.
8. Gambusia. Lifespan 2 years.
Gambusia is a freshwater inhabitant of the United States. She lives for two years. Although Gambusia, which breed in household conditions, has a longer life than its relatives living in salt water. The lifespan of females is also slightly longer. The life of Gambusia in salt water is protected from many predatory fish who cannot live in such an environment.
7. Chameleon. Lives for 1 year.
Only the Panther Chameleon has such a short life. In fact, it has the shortest lifespan among the chameleon family. Panther chameleons are native to Madagascar, its northern and eastern parts. Their frequent mating is due to their short life span. An interesting fact is that all chameleons of this species disappear before the next generation hatches from the eggs. The rapid color change is its most outstanding feature. This gives them the opportunity to mingle with environment. The chameleon's diet consists mainly of crickets and worms.
6. House mouse. Lifespan 1 year.
The lifespan of this regular mouse only lasts for a year. But predators such as cats significantly reduce life span these small rodents. Their bullying also contributes to this. toxic substances. House mice are also susceptible to diseases during hair growth. And their fertility is associated with such a short life.
5. Dragonfly. Lives 4 months.
There are 5,000 species of dragonflies. The maximum lifespan of these beautiful insects is approximately 4 months. But most of them do not live to this point, as they become prey for spiders, birds, lizards and frogs. Strong winds or a sudden change in weather can prevent a dragonfly from hatching from a larva. After passing through the larval stage, the dragonfly can easily fly, this makes the inexperienced dragonfly easy prey for hunters. They also cannot live in cold conditions. The peterka is among the animals that have the shortest life.
4. House flies. 4 weeks.
Houseflies are the most common type and the most annoying of all insects existing in our homes. The entire life of this fly is limited to a four-week period. Insects living in the conditions of our home have a slightly longer life than those living in conditions wildlife. Over the course of its entire short life, one such fly can lay up to 1000 eggs.
3. Ant drone. Lives for 3 weeks.
An ant drone is a male member of a colony of ants. His life cycle is 3 weeks. These ants have a lazy character and never overwork. An ant colony is always controlled by a female. It is interesting that drone ants die after they mate with a female. It turns out that these ants of this type still play important role his life in the colony.
2. Gastrotrich. Lives for 3 days.
These are gastrociliated worms - inhabitants marine environment. They grow to their maximum size 3 mm throughout its three-day life. It has a transparent body and glows. To stick to others aquatic inhabitants they use their thousands of sticky tubes in their lower abdomen. Gastrociliated worms have both female and male sexual characteristics.
1. Mayflies. They live 24 hours.
The shortest living animal. These insects have the shortest life on earth. It lasts only 24 hours. They are also called ephemeral insects. There are 2,500 species of mayflies. In fact, many members of this family die within a few hours. They exist as nymphs. The only purpose of their life is the reproduction of their own kind. For this short term they form groups and dance together on all available surfaces.
When asked which animal has the most short memory given by the author Oriy Katerenchuk the best answer is It is a misconception that it is a goldfish.
A goldfish that lives in an aquarium, contrary to the supposedly generally accepted fact, does not have a “3-second” memory.
Research conducted in 2003 at the School of Psychology at the University of Plytmouth showed that goldfish’s memory “works” for at least three months, while recognizing shapes, sounds, and colors. To get a treat, they were taught to lower a small lever.
Later, in the course of these studies, the lever was adjusted so that it was activated only one hour a day and the fish quickly learned to activate the lever at the desired hour.
Several similar experiments have shown that fish in large aquariums or cages, it is not difficult to accustom them to feeding at one time and in one place when a certain sound signal is given.
Also, goldfish, when swimming in an aquarium, do not touch the wall, not because they see it, but because they use a special system that is sensitive to the pressure surrounding the fish itself. This system called the lateral line. Exist individual species fish living in caves that are well oriented in pitch darkness only using your sideline.
Another misconception: a pregnant goldfish cannot in any way be an example of “utter stupidity” (pregnant, and blonde at that). The fact is that fish, including goldfish, in principle cannot be pregnant - they lay eggs, which are fertilized by males right in the water.
.I could be wrong, but it seems to me that in children. They don’t plan anything, they live in the present - in the moment, in the moment. That is, not the future and not the past.

Answer from Caucasian[newbie]
For "_ one_such_Victoria_ Higher Intelligence (202690)" specially:
1. There is a memory, there is a reflex - you " higher intelligence" - you are confusing and deeply mistaken... the presence of a reflex does not determine the properties of memory....
2. The lateral line is a system of orientation in space - of absolutely all fish, the goldfish has nothing to do with it - the only question that remains is how different this species is from others...
3. Regarding “pregnancy” - you are also mistaken - there is a place where the female will spawn, and every fish has a great variety of ways to spawn on the way to this place 😉
4. Regarding children, I personally think that children are born geniuses - but parents successfully fight this - especially about parents like you - this is especially relevant....
So - if you don’t understand me - then - 6 seconds of memory is not only about goldfish- it’s also about your person 😉
Changes in metabolism, brain-to-body size ratio, habitat, and many unknown things affect the lifespan of different animal species. Some species live for hundreds of years
Changes in metabolism, brain-to-body size ratio, habitat, and many unknown things affect the lifespan of different animal species. Some species live for hundreds of years, while others can live for a few hours. In this collection you will learn about the life expectancy of animals that have the shortest life span on planet Earth.
Domestic Rabbit (6 years old)
Rabbits are small mammals found in various parts of the world. Domestic rabbits have an average lifespan of only 6 years. These animals differ in size and colors. Obesity and uterine cancer are the main diseases of rabbits that affect their short life expectancy. High consumption of root vegetables and fruits also causes many health problems. Rabbits demand a large number of water every day and careful care. But nature took care of this problem by endowing these animals with a hyper-developed reproductive function.
Guinea Pigs (4 years old)
Guinea pigs are attractive social animals native to South Africa. This cute variety has a shorter lifespan of only 4 years. Guinea pigs are susceptible to a range of diseases. They also require intensive care and feeding at regular intervals. Only proper care can extend the lifespan of guinea pigs to 4 years. Among the diseases of this animal, I most often highlight bronchitis, scurvy and excessive obesity.
Mosquito fish (2 years)
Mosquito fish are freshwater inhabitants of many bodies of water in the United States. The lifespan of this fish is less than two years. Frogs and other fish often prey on mosquitoes, which also contributes to this duration. Because of this factor, the fish has adapted to life in salty water, where it cannot be attacked by predators. Mosquito fish can live in environments with water temperatures up to 42 degrees Celsius.
Chameleon (1 year)
Among the chameleon family, panther chameleon has a shorter lifespan - only 1 year. This species lives in the Northern and Eastern parts Madagascar. This chameleon reproduces more often due to more short duration life. Interestingly, all adults die before the next generation emerges from the eggs. Crickets and worms are the main food for chameleons. They drink a lot of water and instantly change color, easily hiding from predators.
House mouse(1 year)
The house mouse cannot live longer than 11 months. This one has small mammal a shorter lifespan, which is actually made even shorter due to the very harsh environment in which this species lives. The main threats to this rodent come from people and their pet cats. The mouse is very difficult to catch, as it runs very fast and can easily hide in the most unpredictable places. Due to their short lifespan, mice reproduce very intensively.
Dragonfly (4 months)
There are 5000 various types dragonflies But this beautiful variety has a shorter life period at 4 months. Most dragonflies are captured by predators before they reach old age. Being in the form of a larva, these dragonflies cannot fly - this only makes the job easier for predators. Sometimes strong wind and sudden climate changes prevent the dragonfly from transitioning from its larval form.
Flies (4 weeks)
Houseflies are the most common and annoying insects in the world. They live for more short period- no more than 4 weeks. Flies grow from larvae in just a few days. Within the short life cycle of each housefly, the female lays up to 1,000 eggs. Flies are considered one of the main spreaders of diseases, which they carry by flying around the house in search of food.
Male ant (3 weeks)
Male ants live within an ant colony and their life cycle is only 3 weeks. Unlike regular worker ants, males have wings and are very lazy. Ant colonies are always founded by females. Males die immediately after mating with females.
Gastrociliary worms (3 days)
Gastrociliary worms, or gastrotrichs, are one of the marine microorganisms. They grow to a maximum size of 3 millimeters, and live for 3 days. Gastrotrichs are often attached to other water bodies. Their transparent body contains male and female organs for reproduction. Gastrociliary worms most often swim with the current.
Mayflies (24 hours)
Mayflies have the shortest lifespan on Earth, only 24 hours. This species is also called ephemeral due to its shortest lifespan. There are 2,500 different species of mayflies in the world. In fact, most of them die within a few hours, or even a few minutes. the main objective mayfly - reproduction of offspring. It's interesting that they digestive system also performs respiratory functions. Within this short period of life, they form groups and literally dance on every possible surface.
Top 5 animals with better memories than humans
4 (80%) 2 votesMan considers himself the crown of evolution, because it was he who invented airplanes, computers and the Internet. However, in comparison with some species of animals, we cannot stand any competition in terms of remembering numbers, objects, and the effectiveness of long-term and short-term memory. We will introduce you to animals whose memory is much better than that of humans.
Repeatedly “glorified” in science fiction films, chimpanzees actually demonstrate the wonders of short-term memory. A comparative experiment was conducted at Kyoto University (Japan).
A group of chimpanzees were taught to count to ten and held a competition with a group of people on the accuracy of remembering numbers flashing on a computer screen in different sequences. The test consisted of reproducing the location of numbers in the correct ascending order. Chimpanzees performed much better than humans.
The most interesting fact is that the duration of display of numbers on the screen did not affect the quality of their memorization and reproduction. Scientists have unanimously concluded that chimpanzees have an amazing photographic memory.
While the trainers were teaching sea lions cheap tricks, they noticed the extraordinary long-term memory abilities of these clumsy sloths. Scientists from the University of California Santa Cruz taught a sea lion named Rio to remember and identify similar items. She was shown cards with symbols, among which she identified the same ones.
However, the most surprising thing happened ten years later, when scientists decided to repeat this experiment with Rio again. She was shown not only symbols, but also numbers and letters, which she successfully identified and found a pair for. Even after so many years, considering that sea lions live no more than 25 years, Rio showed truly phenomenal long-term memory.
3. Elephant
Elephants always know where each member of their family is, regardless of direction or distance. An elephant is able to remember and track the locations and movements of up to 30 members of its herd.
This ability is realized with the help of a mental map, which the elephant draws up and keeps in memory, updating it with the help of a sensitive sense of smell. Thus, elephants use the “elephant” lobe of their brain in constant activity, which indicates the high performance of working memory of these amazing animals.
What is so special about the memory work of octopuses? Unlike other invertebrates, octopuses have well-developed short-term and long-term memory, which works through one and a half billion neurons.
Moreover, its active memory is absolutely autonomous and does not depend on passive long-term memory. If people could also selectively use their memories, their genius would have no equal.
1. American nutcracker (Nucifraga columbiana)
This little bird can remember the location of 33,000 pine nuts. The most amazing thing is that they hide small nuts in fallen leaves and easily find them under the snow in winter. This bird has amazing spatial memory, which helps it remember individual objects and reproduce their location.
Moreover, the hippocampus of the nutmeg (the part of the brain responsible for the transition of short-term memory to long-term memory) continues to produce neurons in mature age. This means that while human memory deteriorates with age, hers only gets better.
Amazing animal world continues to amaze us with his miracles. How many more secret abilities do our little brothers keep that are yet to be revealed?
Since the working memory of the human brain can only work in four directions. This conclusion was reached by American psychologists, the results of whose research are presented in the scientific publication Proceedings of the National Academy of Sciences.
For a long time it was believed that a person can simultaneously remember up to seven different objects. This theory was first voiced back in 1956 by Harvard University psychologist George Miller. As a basis for this statement, he took telephone numbers that use no more than seven digits. As a result of his research, he derived a formula according to which a person’s short-term memory can simultaneously contain seven plus or minus two objects.
However, Nelson Cowan, a psychologist at the University of Missouri-Columbia, noticed that when a person remembers a phone number, he subconsciously breaks it down into blocks of three to four digits, which became the basis for his research in the field of short-term memory.
After conducting a study, scientists came to the conclusion that the capabilities of this memory are more modest - it has no more than 4 vectors, which is why it is much easier for people to remember numbers from groups of 4 each, and the maximum tasks that a person can perform simultaneously does not exceed four.
American psychologists conducted a series of different experiments where subjects were asked to perform basic visual, logical, mechanical and cognitive tasks, and came to the conclusion that people, regardless of race, gender and age, are able to simultaneously operate with a maximum of four objects. This statement is true both in relation to experiments with colors (squares of 4 or 5 colors), and in relation to the faces of other people, performing simultaneous work - memorization was limited to four vectors of thinking.
According to psychologists, the vast majority of people have processes limited to 3-4 vectors; for a small number of “lucky” people, the number of vectors reaches 5. The University of Missouri-Columbia says that even in unique cases when people can remember a lot of information the first time , everything ultimately comes down to 4 main vectors, the rest depends on the ability to manage them.
Another conclusion that scientists have come to is the direct dependence of intelligence on memory. " Logical processes in human cognition also appears to be tied to working memory. The information that you can hold in your head at the same time is the information from which you make inferences. The more information there is, the more logical and quicker conclusions you draw,” says Nelson Cowan, one of the researchers from the United States.
This means that if you forgot why you went to the next room or where you put your glasses, there is no need to worry: scientists say that this is quite normal, since the human brain is not capable of storing a lot of information in working memory. Working memory is even more quick view short-term memory in the human brain. With some degree of convention, human working memory can be compared to processor cache memory - it is small, but it is the fastest.
Interestingly, in ancient times it was believed that memory processes were carried out in the liver. Then people came to the conclusion that memorable information is deposited in the bones of the skull. The ancient Greek philosopher Socrates believed that there was a kind of wax tablet in the head on which all the necessary information was recorded.
Even at the beginning of the last century, it was believed that a person is born with a brain as clean as a sheet of paper. Modern research show that embryonic memory is formed as early as 20 weeks after conception.
By the way, memory four year old child the same as that of an adult. The only difference is that it is not yet developed. And according to recent studies, 19-year-old people have the best memory parameters. For early risers, memory productivity is maximum from 8 to 12 am, and for owls - from 8 to 12 pm
Occupation affects memory. It is preserved better than others in artists (thanks to constant training - memorizing texts), scientists (all parts of the brain work hard) and beekeepers (if they consume bee products, which are rich in microelements that help improve memory). So, Mozart, having once listened to the polyphonic spiritual composition Allegri wrote down an exact note-for-note copy of the work overnight. The famous archaeologist Schliemann by hard training achieved that the next foreign language learned it in 6-8 weeks.
Research shows that drinking alcohol leads to memory impairment, especially for faces. It is known that the commander Alexander the Great knew 30,000 soldiers of his army by sight.
Among the latest scientific discoveries in the work of memory - research by scientists at the University of Dusseldorf. They argue that just a few minutes of dozing can significantly improve a person's memory, and emphasize that it is not sleep that brings benefits to memory, but the process of falling asleep. The fact is that during the process of falling asleep, a period of memory processing occurs, and deep sleep plays big role in performing several basic functions, such as restoring erroneous connections in the brain.
