Welcome to the Top 10 Animals with the Worst Memory in the World. Read on to learn more!
Everything can be stored in the short-term memory of animals, but it is quickly forgotten. Animals also have a wide range of specialised memories that can only remember a specific type of knowledge but store it for a very long time. For the animals on the top 10 animals with the worst memory in the world below that’s not the case.
The memory of an animal varies according to species. However, only a very small number of animals would perform well in terms of a short-term memory test.
As a result, the focus of this blog will be on the some of the animals with the worst memories in the world.

Chimpanzees are large apes found in central and western Africa. They and baboons share 98.7% of our DNA, making them our closest living relative. Humans and chimpanzees may have shared an ancestor as far back as seven to thirteen million years ago.
Seeing chimpanzees on this list of creatures with a terrible memory may surprise many people. We regard chimpanzees as some of the most intelligent creatures on the planet. If not the smartest, at least one of the best.
They are capable of tackling a wide range of challenging tasks and issues. The region of chimps’ brains responsible for learning and development never stops growing, which explains why they are so brilliant. It is fairly similar case for humans.
Chimpanzees are our closest living relatives, sharing 98% of our chromosomes. But why does the chimpanzee have such a large brain but a weak short-term memory?
Chimpanzees have been shown to forget an experience within 20 seconds, according to National Geographic. Since they are our closest ancestors, their findings surprised biologists.
Humans are thought to have developed a capacity for remembering long after we separated from our evolutionary ancestors.
As a reminder, short-term memory is different from long-term memory, and if information isn’t important to the animal, unlike where food is or how to avoid danger, it will be forgotten after 20 seconds. Earning chimpanzees a spot on the list of top 10 animals with the worst memory in the world.
Bees, like wasps and ants, are insects with wings. Aside from the pollination tasks they perform, bees are well-known for their honey production, especially the western honey bee. Apidae is the genus of bees, a monophyletic lineage. Anthophila is the term given to the clade in which they now reside. Bees belong to seven different taxonomic families, and there are an estimated 16,000 or more species around the world.
Nectar and pollen are the primary sources of energy for bees. Where pollen is the primary source of protein and other nutrients for bees. For their larvae, the bulk of pollen provides a source of nutrition. Insect predators such as bee-wolves and dragonflies prey on honeybees, as well as primates and birds like bee-eaters. Bees’ short-term memory is quite weak, despite their amazing abilities.
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.
Most baboons live on the ground and eat a wide variety of foods, such as fruit, roots, grubs, and other insects. As many as five to 200 or more baboons can be found in a single troop of females and juveniles, which may also include a few transient males. Around puberty, male baboons leave their birth group. In contrast, females remain with their birth group throughout their lives. It is common for them to survive for between 20 and 30 years, but they can even live for up to 40.
Baboons are highly intelligent primates who cherish their relationships with their families but have a low memory. Biologists have found that baboons can understand words and language in a logical way.
In recent years, the number of people owning hamsters as pets has skyrocketed. Hamsters are really forgetful. Their owners say that hamsters lose track of what they are doing in the middle of things.
Hamsters are known for their food hoarding behaviour. They transport food to their underground lairs in the large cheek pouches. When their cheeks are full, their heads can appear to grow by a factor of two or three. Hamsters shed their summer weight in preparation for the winter. Hamsters that are kept as pets may also have this side effect, and it has been linked to more exercise.
The hamster’s short-term memory is thought to be no more than three seconds. Which is why these household pets are on the list of top 10 animals with the worst memory in the world. As far as hamster intelligence is concerned, there hasn’t been much research done to find out. There are certain rodents, though, that can recognise you and even reply to your name if you train them for long enough.
Since pinnipeds spend so much time in the water, they have an amphibious way of life. Seals only leave the water to breed, give birth to young, shed their old skin, rest, regulate their body temperature, or flee from water-based predators. In reaction to extreme environmental conditions, such as changes in ice cover, a number of species are known to move long distances.
To keep themselves warm in the frigid waters, seals have a layer of fat under their skin called blubber. Having a water-resistant fur coat makes it easier for them to glide through the waves. The hairs on a seal’s face aid it in spotting prey in the dark and murky waters. In general, seals live 25–30 years; females tend to outlive males.
Seals are one of the most intelligent species of animals. They can understand words and commands, as well as signs and human laughter, but they have poor memory.
The giraffe is the tallest mammal in the world because of its long neck and towering legs. Even just the legs of a giraffe are taller than most people as they stand at nearly 6 feet. Because of their large legs, giraffes can run at speeds of up to 35 mph over short distances and 10 mph over longer ones. These intriguing animals usually travel in small groups of approximately six or seven through the wide grasslands.
Giraffes may fight by slamming their long necks and heads into each other. In most cases, the contests conclude peacefully when one animal gives up and walks away.
They look like they’re really clever creatures. But their short-term memory spans only a few seconds. A giraffe’s short-term memory isn’t even enough to remember that they have done something.
It’s the slow, methodical movements that give sloths their name. Like their popular names in various different languages for example, French paresseux, the word “sloth” simply means “laziness.” Slowness allows them to feed on leaves, which are low in energy, and it keeps them hidden from predatory hawks as well as cats that hunt by sight. Despite their inability to walk, sloths are able to swim.
It’s not a major surprise that sloths don’t have outstanding memories because they don’t really shout. In the movie Ice Age, Sid the Sloth should have given you a fair sense of how naive these animals are.
It’s not uncommon for them to have such poor visual recall that they mistake their arms for tree branches, hold on with their opposing arms, and fall to their deaths. Worse, short-term memory and forgetfulness are the main challenges for this creature. It’s no wonder sloth are among the top 10 animals with the worst memory in the world.
Turkey has a common lineage with grouse, pheasants, and other fowl that can be traced back over 20 million years in North America.
Newborn turkeys stay close to their mother throughout the year. Despite the fact that wild turkeys prefer to roost in trees, the mother keeps her young at ground level to protect them from predators until they are big enough to fend for themselves.
Despite their high speed, wild turkeys can only fly for a short distance before crashing to the ground. Most domestic turkeys, on the other hand, are unable to fly because they have been bred to be much larger than they would be in the wild.
Turkey don’t appear intelligent, and they also have issue with with their memory which is one of the worst.
The ostrich is a big, flightless bird exclusively found in Africa’s open country. The males are primarily black, with white plumes on their wings and tails, while the females are mostly brown. Reddish and blueish in colour, the head and most of the neck are lightly draped; the legs, notably the muscular thighs, are bare. The head is small, the bill is short and broad, and the large brown eyes are framed by thick black lashes.
At least they can blame their macho behaviour on the fact that they can not recall how foolish they are. The short-term memory of only 10 seconds means they may be chasing something without even knowing why. Their wide-set eyes and stupid-looking heads only serve to reinforce the general belief that these animals are not intelligent in the least.
Most snakes have very poor or no memories at all. This may come as a surprise given the plethora of snake-horror movies we’ve seen over the years. While they may be unable to recall details, it is more likely that their brains aren’t built to make emotional connections to the events they encounter.
Since they can learn to tell the difference between predator and prey, your pet snake may or may not be aware of your existence.
Animals or items they’ve previously encountered have scents that they can identify and remember, but they have no memories associated with them. Even if they can’t remember why they should be doing something, most snakes have an innate sense that it’s the right thing to do.
Despite popular belief, snakes have no concept of being pets and may not even recognise their owners. They also have no capacity for building a relationship with humans, such as seeing them as more than just an animal that hasn’t impacted them and would be too big to be prey, so they simply leave the others alone.
Animals without brains
It’s fascinating to learn how animals without brains function and adapt to their natural environment. Many hours of research have been devoted to learning everything there is to know about these unique animals. It is only in water that animals without brains can be found. The majority of these animals attach themselves to rocks or the ocean floor to survive. And the reason they make the list of top 10 animals with the worst memory; is because you need a brain to have a memory!
Sea stars can be found living in salt water in all oceans, from the warm tropical waters to the freezing bottom. The suction-cupped feet of sea stars allow them to hunt for mollusks such as clams, mussels, and oysters.
The starfish is able to tell the difference between light and dark because it possesses small eyes at the ends of each arm. They’re good at spotting movement, but they can’t do much else. Just the right amount of information to keep an eye out for food and adversaries. Because it contains all the essential sensors it needs to remain attentive, this animal does not require a brain.
They are a key portion of the phylum Cnidaria and are known as jellyfish and sea jellies informally. Although some jellyfish are fixed to the seafloor by stalks rather than being mobile, most have umbrella-shaped bells and trailing tentacles.
Rare among creatures lacking a brain, jellyfish move about during their life cycle. The jellyfish may migrate with the water currents. Squirting water from its mouth can also be used to propel itself ahead.
Sea urchins, like sand dollars and starfish, are a species of spiny sea creature. Because of their hard, spherical, and spiky bodies, they may readily be mistaken for shells or pebbles.
Sea urchins are simple creatures, yet they have a formidable protection system. Skin, tissue, and even bone damage can result from a single sting from one of these venomous insects.
If you’ve ever trodden on a sea urchin, you’ll know just how dangerous they can be. When you’re at the beach, keep an eye out for these fellas.
Echinoderms, which include sea cucumbers, are creatures that live in the water. 1,250 species have been identified so far, and many resemble soft-bodied cucumbers in appearance. Although some sea cucumbers reside in the shallows and others in the deep ocean, they are all ocean dwellers. It’s not uncommon for them to be partially buried beneath the ocean’s surface.
There is something endearing about the small worm-like critters. Most of the animals mentioned in this article eat plankton that floats on the surface of the ocean. They can be found in every corner of the globe, and their skin is made of a material that closely resembles leather.
A polyp is a hollow cylindrical structure linked to a surface at its base by an internal skeleton. A mouth enclosed by tentacles can be found at the free end. Nematocysts, specialised stinging structures that paralyse animals, are found on the tentacles that gather food.
As with jellyfish, corals are members of the “Cnidarian” family of marine organisms. Asymmetrical bodies and the ability to sting their foes are common features among the creatures.
You may mistakenly believe corals to be plants, but they are, in fact, real, breathing creatures. As we’ll see, they are pretty simple animals, which makes sense given that they don’t have a brain.
Coral polyps are the tiny creatures that make up the coral. Jellies devour zooplankton, and corals do the same thing. Small tentacles are used to collect plankton at night when they emerge from their burrows. The tentacle arm is pulled back inside and eaten as soon as something is caught.
Summary on Top 10 Animals with the Worst Memory in the World
Amazingly, a surprising number of animals in the world possess exceptional recall abilities. Dolphins, and dogs, for example, have remarkable memories and can retain information for long periods of time.
Information can be stored for a long time in specific memories. For example, observe the ability of animals to recall other people, regions rich in food, or if some foods are hazardous for long periods of time. To the animal, this is vital information to retain as it pertains to their survival instinct. In contrast, the memories of events that set off these particular systems vanish after a few seconds or minutes.
Whenever an incident is not worthy of an animal’s notice and is not critical to their survival, they will quickly forget about it. The median animal’s short-term memory is approximately 27 seconds.
After 27 seconds, if no significant event occurs in the animals’ brains, the incident is already a forgotten memory.
