If threatened, they make large groups and run away together from predators. Can remember and identify animal faces (other sheep in the same group and predators they have met ) 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 traps, they won’t get trap anymore. They have a strong social relationship, 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 homes by identifying trees, bushes, flowers, etc. Every fall, they bury thousands of nuts in many places and they can remember where to find all the nuts during winter. To fool their rival, they even make some “fake nuts burial”.
In fact, they’re one of the cleanest and odorless animals, they have emotions, sensitivity, hurt feelings and are easily bored. Very sociable to humans and trainable. Some say they are more trainable than dogs.
Trainable, can recognize radio, television and 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.
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, elephants have their own “death ritual”. They use their trunks to take a bath, drink, get food, play, even use tool (e.g. painting). They can mimic sounds, a few human words and can understand the meaning if they’re well-trained.
Monkeys can imitate human 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 relationships. If two monkeys are 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 strong friendships in a group. Whales can “sing” with their sound and can make many different “songs” in a good tone.
Dolphins are 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 the best communication system among animals.
