While humans are considered the most intelligent species, there are many animals that exhibit remarkable intelligence. Here is a list of 13 animals that are among the smartest on Earth, and their abilities might just surprise you! The order of this list is also unexpected, as it contradicts common beliefs and folk sayings about certain animals’ intelligence.
13. Parrots – Masters of Mimicry and Speech
Parrots are known for their impressive ability to mimic human speech. With their excellent memory and learning capabilities, parrots can speak whole phrases or complete sentences if properly trained. They also use their beaks and feet skillfully, demonstrating a complex understanding of logic, such as unlocking locks and opening boxes.

12. Dogs – Loyal Companions with Emotional Intelligence
Dogs are not just loyal pets, but they also possess high social intelligence. They can learn hundreds of words, follow human instructions, and, most remarkably, sense their owner’s emotions. Dogs offer comfort with their eyes and actions when their human companions are sad, which is a unique ability among animals.

11. Goats – Intelligent Problem Solvers
Goats, once considered foolish, have proven their intelligence in experiments. They can learn to pull strings or press levers to receive rewards. Impressively, they remember these procedures even after almost a year, showcasing an impressive long-term memory.
10. Mice – Small but Clever
Mice are renowned for their adaptability and learning abilities. They can remember their way through a maze, finding faster routes with each attempt, and even learn to “bend the rules” to achieve their goals. This is why mice are commonly used in psychological and behavioral research.
9. Octopuses – The Ocean’s Brainboxes
As the most intelligent invertebrate, octopuses can open jars, solve puzzles, and use tools to aid in hunting. With their complex nervous system, they can observe and mimic the actions of others, a rare ability among sea creatures.
8. Pigeons – Super-Remembering “Secretaries”
Pigeons can recognize hundreds of images over long periods and were once trained to carry messages during wars due to their excellent navigation skills. They even recognize themselves in mirrors, indicating a high level of self-awareness.
7. Squirrels – The Forest’s Strategists
Squirrels possess an extraordinary memory, capable of remembering the locations of hundreds of seed-hiding spots for several months. Moreover, they can fake-dig holes to deceive thieves, demonstrating their intelligence and cunning in protecting their resources.
6. Pigs – Smarter Than You’d Expect
Pigs, often associated with foolishness, have been scientifically proven to be quite the opposite. They can learn to open doors, solve simple puzzles, and use mirrors to find food. Notably, pigs can also learn by observing their peers, a skill not possessed by all species.
Surprisingly, pigs are smarter than both dogs and parrots.

5. Crows – Sky Strategists
Crows are incredibly smart problem solvers and planners. They drop hard seeds onto roads so that cars run over them, cracking the shells and providing them with food. They use twigs as tools and remember people who have treated them well or badly. They even deceive their fellow crows to get rewards!
4. Elephants – Superb Memory and Emotional Depth
Elephants are not just large; they also have an incredible memory. They remember migration routes spanning hundreds of kilometers, use twigs to swat insects, and perform “funeral” rituals for their deceased. Elephants can also paint, follow instructions, and have deep social connections.
3. Orangutans – Wise and Emotional Primates
Orangutans use tools to obtain food and pass on knowledge to future generations. They develop their own communication systems, live in groups, and have a distinct culture. These behaviors highlight their close intellectual ties to humans.
2. Dolphins – Underwater Communication Experts
Dolphins are famous for their communication through sound waves and whistles. They coordinate hunting, play with their peers, follow instructions, and use objects like sponges to protect themselves. Dolphin mothers teach their calves survival skills over many years, akin to human education.
1. Chimpanzees – The Smartest Animals After Humans
Chimpanzees top the list due to their superior intelligence. They use tools, learn sign language, remember the faces of loved ones for years, and express emotions like joy, sadness, and anger. Some individuals even combine signs to convey their thoughts, similar to how humans communicate verbally.
The folk saying, “stupid as a pig,” might need to be reconsidered after learning about this list. Each animal has its unique way of displaying intelligence, be it through communication, learning, or survival strategies. Understanding animal intelligence better not only fosters respect for other life forms but also plays a crucial role in protecting the natural ecosystem, which is increasingly under threat.
