What animal is the smartest after humans? Intelligence Rankings, Facts and Surprising Examples
Have you ever wondered what the smartest animal other than humans is? For decades, scientists have been observing animal intelligence, to determine which animals can solve problems, communicate, use tools, and even look at themselves in a mirror. Although no one species is declared the winner in each category, most experts rank most of the mammals, birds, and dolphins as the most intelligent animals on Earth, with the great apes and dolphins leading the way.
It depends on the measure of intelligence. Certain animals have superb memories. Others are good at communicating or problem solving. This book examines the contenders and how they have been deemed the smartest creatures after humans.
What Animal Is The Smartest After Humans?
Quick Answer
Scientists believe that the chimpanzee is the cleverest animal after man due to their advanced problem-solving skills, the use of tools, social intelligence and communication.
But dolphins, orangutans, bonobos, elephants – and even crows – exhibit amazing intelligence as well.

How Scientists Measure Animal Intelligence
Researchers consider a few factors before determining what animal is the smartest after humans.
Problem-Solving Skills
Does the animal need to work to reach a goal?
Tool Use
Is it able to make or utilize tools to resolve problems?
Memory
How good is its memory of places, things or experiences?
Communication
Is it able to communicate individual data to others?
Self-Awareness
Does it recognize itself in a mirror?
Social Intelligence
Is it able to interact and comprehend relationships in a team?
Animals with high scores in multiple of these areas tend to be very intelligent
Why Chimpanzees Are Often Ranked Number One
Chimpanzees share 98% of their DNA with humans. This close relationship is the reason for many of the similarities in behaviour and learning.
Tool Usage
Chimpanzees use sticks to gather the termites from the nests. They also employ rocks to break the shells of nuts.
Strong Memory
Studies have revealed that some chimps are able to learn number sequences far quicker than many humans.
Learning Ability
They can be taught symbols and basic sign language to communicate with humans
Social Skills
Chimpanzees live in organized communities, in which they cooperate, form alliances and settle conflicts.
Chimpanzees are often used as examples when talking about the smartest animal after man due to these skills.
Dolphins: The Ocean’s Geniuses
Dolphins always appear high among lists of animal intelligence.
Self-Recognition
Among the few animals that can identify themselves in a mirror are dolphins.
Advanced Communication
Communicate by whistles, clicks and body language.
Teamwork
During hunting, dolphins work together and help injured members of their group.
Learning New Behaviors
They can become accustomed to commands, retain them for years, and adjust to new scenarios.
Many scientists believe that dolphins could be as smart as chimps in some respects.
Orangutans And Their Remarkable Minds
Orangutans are one of the most intelligent primates.
Tool Creation
In the wild, they use sticks and leaves as tools.
Long-Term Planning
Scientists have witnessed orangutans making tools that were not necessary to make at the moment.
Learning Through Observation
Many of the survival skills that young orangutans acquire can be learned by observing adults.
They are also very good at anticipating and can be one of the smartest animals after humans.
Bonobos: Masters Of Social Intelligence
The bonobos are close relatives of chimpanzees.
Understanding Relationships
They are able to maneuver rather impressively through complicated social systems.
Communication
Bonobos communicate through gestures, sounds and expressions.
Cooperation
They collaborate and share resources often to solve the problems.
Bonobos are reputed to be especially smart in the areas of emotional intelligence and social intelligence.

Elephants And Their Incredible Memory
Don’t say a thing twice; “an elephant never forgets” is for a reason.
Outstanding Memory
Elephants can remember the water sources and migration routes for many years.
Self-Awareness
They can be among the few species that do pass the mirror self-recognition test.
Emotional Intelligence
Elephants display feelings of empathy, feelings of loss and social bonding.
Problem-Solving
They are able to use items and collaborate with others to solve problems.
They are not quite as smart as primates, but they’re still pretty darn smart.
Crows: Small Birds With Big Brains
The crow is one of the most unexpected animals that has surprised people with its intelligence.
Tool Manufacturing
Crows can form hooks out of wire, and use sticks to get to food.
Cause-and-Effect Understanding
They know how objects can interact in ways they believe were only possible for humans.
Facial Recognition
Research indicates that crows have a short memory for human faces, and can only recall them for years.
Adaptability
They are adaptable and will learn from experience.
In fact, some scientists equate the intelligence of crows to that of young human children.
Ravens: Problem-Solving Experts
Ravens are members of the same family as crows, and are equally intelligent.
Future Planning
Ravens can remember tools that can be used in the future.
Complex Reasoning
They put themselves to the test using puzzles that involve more than one action.
Social Learning
They watch and imitate successful actions of other ravens.
The skills they can do makes ravens the smartest in the world.
African Grey Parrots And Language Skills
African Grey Parrots have impressed scientists with their powers of communication.
Large Vocabulary
Some individuals learn hundreds of words.
Context Understanding
They can form connections between words and objects, colors, and actions.
Memory
They have a very long memory.
They cannot solve the problems as chimps can, but their language ability is incredible.
Octopuses: The Intelligent Invertebrates
But intelligence isn’t restricted to mammals and birds, as octopuses demonstrate.
Escape Artists
Can open containers and break free from secure enclosures.
Learning Ability
Like humans, octopuses learn by watching and doing.
Adaptability
Adjusts readily to new situations.
Invertebrates are the smartest species, with octopuses being the smartest species.
Are Pigs Smarter Than Dogs?
This is a debatable question.
Why Pigs Rank Highly
- Excellent memory
- Fast learning ability
- Strong problem-solving skills
- Ability to understand symbols
It has been suggested that pigs may have superior cognitive abilities in some tasks compared to dogs.
Intelligence is complex, however, and so comparisons relate to the skills measured.

This ranking may differ and depend on the criteria used by researchers.
Why There Is No Perfect Answer
What animal is the smartest after humans? It’s worth remembering that intelligence is multi-faceted when deciding on which animal is the smartest after human beings.
A dolphin could be better at communicating than a chimpanzee.
A crow can be superior to both in certain tasks involving tools.
The elephant’s memory may be better.
Some problems that may be solved by an octopus can’t be solved by mammals.
Each species developed in their environment and thus took on different forms of intelligence.

Conclusion
There is no universal answer to what animal is the smartest after humans. Nevertheless, chimps are still the best bet because of their tool use, memory, communication and social interactions. Dolphins are highly aware and can communicate with each other. Other species, such as elephants, crows, ravens and orangutans, are still pushing the limits of our conceptions of intelligence.
The most that modern research has revealed is that intelligence is manifested in a variety of ways throughout the animal kingdom. As scientists gain more knowledge, they are discovering more and more that humans are not the sole beings who can think, plan and problem solve.
