While the story of crows using rocks to access water is well known, there are many other animals exhibiting intelligence that often goes unnoticed. Researchers have long grappled with understanding animal intelligence, as comparing animals to humans—or even animals to other animals—can overlook unique survival strategies. The ways animals adapt to their environments are truly astonishing, and you might be amazed by the clever solutions they have devised to solve complex problems.
10. Chimpanzees with a Memory That Outpaces Humans?
Chimpanzees are famous for their intelligence, which is why they are often studied by scientists. One experiment tested their memory by hiding food under colored boxes. The chimps were then asked to point to the box that contained food, and after a brief 15-second delay, they were asked to choose again. On average, chimps could remember 4 items, with the top performers recalling up to 7. This is actually quite similar to the memory performance of humans on similar tasks!
But a chimp's memory doesn't stop there. Ayumu, a remarkable chimp, outshines humans in certain cognitive challenges! In one task, numbers are shown on a screen for a split second before being hidden under white boxes. While humans often struggle to recall the numbers, Ayumu effortlessly memorizes sequences of up to 9 numbers. Don't worry, though, we’re still a long way from having to worry about 'Planet of the Apes'!
9. Elephants Know the Importance of Teamwork
It's no surprise that elephants are incredibly intelligent. Their brains are three times the size of a human’s, which means they have three times as many brain cells too! Elephant intelligence is widely researched, and it's been shown that they can learn through imitation, display empathy, and even care for less fortunate members of their herd. These qualities are rare in the animal kingdom, where many creatures focus solely on themselves.
What’s particularly fascinating about elephants is their ability to cooperate for a common goal. In one experiment, scientists placed food in a box, and the only way the elephants could access it was if two of them pulled on two separate ropes at the same time. Not only were the elephants able to achieve this, but once they understood that teamwork was key, they wouldn’t attempt to pull the ropes unless another elephant was nearby. So, if you ever need an extra hand—or trunk—look no further than an elephant!
8. Parrots Are Capable of More Than Just Talking
While everyone knows parrots can mimic human speech, fewer people realize that some of them may also comprehend what they’re saying. A prime example of this is Alex the Parrot, an extraordinarily intelligent bird whose name stood for ‘Avian Language Experiment’. Alex was so clever that he could correctly answer questions designed for six-year-old children, earning him the title of the 'Einstein of parrots'.
Alex was able to recognize both colors and shapes, as well as answer questions about various objects presented to him. He could identify different items by name and compare them using words like ‘bigger’ and ‘smaller’. When other parrots were tested in the lab, Alex would often respond on their behalf and even tell them to 'Say Better'. Even more astonishing, researchers believed Alex had the emotional maturity of a two-year-old child. Sadly, Alex passed away unexpectedly at the age of 31, with the researchers stating that they didn’t think he had reached his full potential yet.
7. Dolphins Can Imitate Human Movements
That title might sound a bit unusual; you might be wondering how an animal without arms and legs can mimic human actions. But that very fact is what makes it remarkable. You’ve likely seen chimps in zoos imitating people around them, but they have the ‘right’ limbs for such actions.
It turns out that dolphins can do something similar, using their flippers and tail to replicate human movements. If a person floats on their back in the water, a dolphin can copy the position; if a human crosses their arms, the dolphin can mimic that too using its flippers. Even more impressively, dolphins have such advanced senses that they can replicate human actions while ‘blindfolded’, which in dolphin terms means covering their eyes with ‘eyecups’.
6. Some Birds Can Plan Ahead
The ability to plan for the future is a trait that distinguishes humans from many other animals. We can prioritize long-term rewards over short-term ones, choosing actions that will benefit us in the future rather than those that provide immediate satisfaction. Interestingly, the western scrub jay, a species of bird, also possesses this ability.
In an experiment, scientists allowed the birds to eat food and then gave them time to store some for later. This way, their immediate hunger would not affect their decision to save food. The birds chose to store food for the next morning, demonstrating that they not only think about the present but are capable of making decisions that benefit them later on.
5. Pigs Can Utilize Mirrors
Mirror use is often a test to see if an animal can recognize itself in a reflection, and surprisingly, few animals can do it. If you’ve ever had a pet, try placing them in front of a mirror and observe their reaction—some may even get upset thinking there's another animal in their space! Pigs, however, are able to use mirrors for more complex tasks.
Pigs were given a mirror in their enclosure for about 5 hours to get used to it, and afterward, a food bowl was placed in a location that could only be seen via the mirror. Almost all the pigs were able to locate the food quickly. This is impressive because it shows they could not only identify the food in the reflection, but also understand that the mirror was a reflection of the real world. Pigs are known for their intelligence, being able to distinguish random scribbles from ones they’ve seen before and even move a cursor on a screen with their snout, so it’s no surprise they can use mirrors effectively.
4. Bonobos Can Learn to Communicate
Like chimpanzees, bonobos also exhibit abilities beyond what one might expect. What sets bonobos apart is the diverse range of skills that some individuals have managed to learn. A remarkable example is Kanzi, a bonobo who learned both sign language and symbols to communicate. Even more impressive, Kanzi picked up some of his sign language simply by watching videos of another intelligent animal, Koko the Gorilla. With the symbols, Kanzi can effectively communicate with researchers.
Kanzi doesn’t just communicate, however—he has also figured out how to sharpen rocks to cut ropes and access food. Along with some other bonobos, Kanzi has learned how to ‘cook’ using an oven, all without direct instruction from researchers. This suggests that animals might not only have the potential to learn cooking, but also to delay gratification in order to improve the quality of their food. It further raises the possibility of advanced tool use among animals, beyond just sticks and rocks.
3. Rat Mazes
The classic experiment of rats in mazes—where cheese is placed at one end and the rat must find its way to it—is more than just a simple task. This scenario actually demonstrates a high level of intelligence. To navigate the maze, rats must process numerous sensory cues and analyze their environment. Even more remarkable, much like elephants, rats show altruism by helping other rats. So, the next time you spot one, remember, it could be on its way to assist a friend!
2. Octopus Mimicry
Octopuses stand out from the rest of the creatures on this list, not just because they are invertebrates rather than mammals, but because of their exceptional problem-solving abilities. As the smartest invertebrates on Earth, octopuses can use their uniquely flexible bodies to tackle challenges in ways that other animals cannot. For instance, an octopus can twist and stretch its arms to open a jar to reach its food. While this might seem simple, keep in mind that jars are designed for hands with thumbs, a feature octopuses lack.
But octopus intelligence doesn't stop there. Mimic octopuses can impersonate other animals to deter potential predators. By observing another creature, they can modify their bodies to resemble it. This impressive skill requires not only an understanding of their own anatomy but also the ability to recognize and imitate the appearance of other species.
1. Cows Are Natural Learners
It might be surprising to see cows on this list, especially given their reputation as simple farm animals. While it may seem like cows are merely grazing and aimlessly wandering in fields, they actually have more complexity to their behavior than meets the eye. Cows form social bonds, avoiding individuals that have treated them poorly and befriending those who have been kind to them. This suggests that cows have a deeper understanding of social dynamics, perhaps more so than some humans!
Another intriguing discovery about cows is that when researchers rewarded them with a treat for improving on a task, their heart rate increased and their movements became more lively compared to when they were given a reward without any specific reason. This suggests that, much like humans, cows prefer to be rewarded for their achievements rather than receiving random rewards.
