you’ll see some animals considered the smartest and most intelligent. I wanted to make top 10 but they’re many different sources so I made top 15. It’s subjective to rank which one is smarter than the other especially some animals on bottom rank, just judge yourself.
If threatened, they make large groups and run away together from predators. Can remember and identify animal face (other sheep’s in the same group, they’ve met predator) can remember and identify human face.
They have a great memory that can recognise themselves in the mirror, can remember hundreds of different images/photos and learn routes to their home from long distances.
Once they’ve experienced rat trap, they wont get trap anymore. They have a strong socialrelationship, maybe stress even die after their partner died. Like dogs, can be trained to sniff out land mines and bombs.
Octopus are the smartest among all invertebrates because they can change color in less than a second, mimicking seaweed, crab, coral, etc. They can use tool with their tentacles (e.g. open bottle).
They can remember their home by identifying trees, bushes, flowers, etc. Every fall, they bury a thousands of nuts in many places and they can remember where to find all nuts during winter. To fool their rival, they make some “fake nuts burial”.
In fact, they’re one of the cleanest and odorless animals, they have emotion, sensitivity, hurt feelings and easily bored. Very sociable to humans, trainable. Some say they are more trainable than dog.
Trainable, can recognize radio, television, they can even check traffic before crossing the street. They’re smart enough to get attention (meow, rub near ankle, follow you, sit on your lap, etc.). Cats can hear and recognise their owner’s footstep or stranger’s footstep.
The man’s best friend, very trainable, sociable to humans, can understand commands and obedience. Can identify and remember animal or human faces they’ve met, they can recognise radio, television, etc. Dogs can be sensitive, jealous and they won’t forget someone hurting them in their entire life.
Parrot can mimic human words, understand the meanings, can remember many words and make sentences. Well-trained, can count up to 6 and can identify many objects. They can answer simple questions and can use tools with their beak (e.g.painting).
They’re the smartest among all birds, can count up to 3. Very creative because they can make and use tools without training (e.g. use branch to gather food). Sometimes they put nuts on the street and wait until car or pedestrian crack the nuts, then eat the nuts.
Elephant can recognise themselves in the mirror, very altruistic. Among other animals,elephant has they’re own “death ritual”. They use their trunk to take a bath, drink, get food, play, even use tool (e.g. painting). They can mimic sounds, few human words and can understand the meaning if they’re well-trained.
Monkey can imitate humans behaviour without training and if well-trained, they can behave like humans (e.g) drink from bottle and ride bicycle). Like human, they have egoism, vain, pride and strong relationship. If two monkeys were fighting, the relatives of one monkey will threaten the relatives of the other monkey.
They can find their relatives separated miles away in the sea for unknown reason but they have their own language to communicate, can call each other and have a strong friendships in a group. Whales can “sing” with their sound and can make many different “songs” in a good tone.
Dolphin is the smartest aquatic animals, they can recognise themselves in the mirror. Very trainable and can hold and use tool with their teeth for painting. They use whistling sound to communicate with best communication system among animals.
