Intelligence of animals

Unlocked cockatoos, dogs with the ability to recognize arithmetic or elephants imitate Korean are interesting features about the intelligence of animals.

>>>New discoveries about crows' intelligence

Bees

According to the researchers, bees can count and classify objects with similar characteristics. They also understand the similarity or difference and distinguish the symmetrical and asymmetric shapes. Professor Lars Chittka of Queen Mary Research Center, UK, said animals with larger brains are not necessarily smarter.

Crows

Behavior studies of human requirements in crows indicate that this is an intelligent animal equivalent to a child. They can manage to get food in small tubes by dropping stones into the water, causing the piece of food to rise. The New Caledonian crow also makes its own tool from small branches and trimmed into a hook to pull insect larvae or ants out of the hole in the trunk.

Dog

According to the research results of experts from the University of British Colombia, Canada, dogs are species that understand arithmetic. The dogs in the experiment found errors in simple calculations like 1 + 1 = 3. A dog can learn 165 words. Super smart dogs, which account for about 20%, can learn at least 250 words and symbols.

Fish

Tropical angels can distinguish larger numbers in smaller numbers and are able to count up to three. Experts suspect that fish even has the same mathematical ability as dogs. However, they need to conduct many other methods to study this animal.

Cockatoo

Cockatoos have been dubbed the ultimate thief in the animal world because they can open most types of locks. In the study conducted by University of Vienna experts, an adult male cockatoo named Pipin was unlocked at the request of experts. While this task can make it difficult for many people, the Pipin takes less than two hours to complete without any help.

Elephants

A male elephant of the Asian elephant named Koshik can mimic human speech in Korean but only those who know this language understand. The current vocabulary of this elephant is Annyong (hello), Anja (sit down), Aniya (no), Nuo (lying down), and choah (good). When experts ask them to do things like sit down or lie down in Korean, they all work.

Goldfish

Goldfish not only listen to music but also distinguish this author from another author. In the study, experts turned on two classical pieces, including Toccata and Fugue in D minor by Johann Sebastian Bach and The Rite of Spring by Igor Stravinsky, near a goldfish tank. The results show that goldfish have no difficulty distinguishing between the two authors. While fish and most other animals like tranquility rather than music, this finding proves that goldfish can detect complex sound properties such as low altitude and timbre.

Snake

Snakes not only attack and kill prey instinctively, but they also monitor the situation of the victim to the end. The degree of tightening and the time for a snake to kill its prey by tightly wrapping is adjusted to the perfect level, corresponding to the heart rate and the weak state of the unlucky prey.

Horse

Horses are considered very loyal animals to humans. According to researcher Carol Sankey of the University of Rennes, France, they are also animals with great memories, can learn and remember some words that people talk to them. If treated and cared for well, the horse will be a long-term friend to the owner and even remembers the caregiver after a long time. The ability to know horses' human voices is also better than dogs.

Dolphin

According to Lori Marino, a neuroscience researcher at Emory University, USA, based on the study of the brain of dolphins, dolphins are the second species after Homo sapiens intellectually. In the future, high-tech devices can allow people and dolphins to chat with each other.
