1. Chimpanzee
This  animal can be found in wet tropical forests and savannas of West and  Central Africa. Chimpanzee are able to learn, perform the tasks of  thinking organization, and has a better memory then any other animal.  They have been known to beat the college educated in the memory test.  They can be taught to use computers to solve numerical problems. These  animals can quickly adapt and perform sign language to communicate with  humans. Chimpanzees have been observed using advanced knowledge tools.  This includes a spear to take animals out of small holes in trees, using  branches to lure and catch prey, using stones to break nuts, and leaves  a sponge to absorb water. They have seen an attack using tactical  maneuvers, such as flanking prey. They often use mental manipulation  within their families. Chimpanzee Genome Project is completed in 2005.  This shows that chimpanzees share 98% genetically the same DNA as  humans. It was approximately four to six million years since humans and  chimpanzees that deviate from the evolution of their common ancestor.  More recently, chimpanzees have been seen teaching sign language to  their babies without human intervention. We were just beginning to  understand the mental abilities of chimpanzees.
2. Bottlenose Dolphin
Bottlenose  Dolphin lives in the warm waters worldwide and is the most intelligent  species of dolphins. It has a very large brain and the cerebral cortex  and the frontal lobe is 40% larger than humans. Cerebral cortex is a  part of the brain responsible for social communications, abstract  information processing, problem solving, and intelligence of a higher  level. Dolphin bottle very easily trained. They have been found to have  the ability to think, plan, solve problems, think abstractly, comprehend  ideas, and learn from previous experiences. They use echolocation to  hunt prey, and certain forms of squeaks and whistles to communicate with  one another. It is also interesting to see that in many occasions this  dolphin show remorse for the other species and the signs of  consciousness. In a story recently, the local dolphin named Moko saved  two Pygmy sperm whales stranded on New Zealand. Whales had been stranded  for hours when Moko appeared and led the pair through the bars of sand  for safety. It is a beautiful sight for locals and become national news.
3. Rhesus Monkey
Rhesus  monkeys are known for intelligence and it has been widely used in  biological and medical research. It has great memory, the ability to  learn, and make decisions for themselves. They use facial expressions  very similar to human and understood by humans. Rhesus Monkey’s have  demonstrated suicidal tendencies, planning attacks, and highly complex  social animals. They have a detailed system of shared vocal similarities  to human communication. Research on the genome sequencing of the Rhesus  Monkey in 2007, conclude that humans and apes share 93% of their  genetic DNA. Humans and apes chromosome mosaic each other.
4. Elephant
There  are three living species of elephants, African Bush Elephant, African  forest elephant and Asian elephant. All the offspring is expected to  inherit the same genetic genius. In many cultures the elephant is seen  as a symbol of wisdom and known for their extraordinary memories. They  create a mental map and is said to remember the exact location of water  holes that feeding them after not visited for years. Elephant brain is  the largest of all land animals. Elephants have exceptional hearing and  they use their ears and trunk to listen. They communicate with the  bellows, roars, like a trumpet call, and can even send voice remotely  using the land. This animal is one of the few species that has shown  mirror self-recognition and identify themselves as independent. This  test is considered as the higher basis for empathy, altruism, and social  interaction in some other species. Elephants have noted a variety of  behaviors. Including actions associated with grief, making music, love,  play, and the use of sophisticated equipment. Elephants have  extraordinary taste for artistic achievement. They can paint a portrait  that expresses itself.
5. African Grey Parrot
African  gray parrot is a species found in West and Central African rain forest.  Parrots is famous to show that they can imitate human speech, but the  African Gray can associate words with meaning and form small sentences.  This bird communicate with each other through songs, calls, and body  language. African Gray’s can easily be trained to have conversations and  activities. They can be managed to imitate, create voices and imitate  sound of household perfectly. One specific example is Alex birds. Alex  can identify more than fifty objects, seven colors, five shapes, and a  numeric value to six. Alex understands the difference between large and  small, above and below, and even show emotion understanding by telling  handlers “to go away” when he became bored with the test. Then there is  the story of the African Gray Parrot in Nagarey, Japan lost from the  owner, wounded, and sent to the animal hospital. While in hospital the  bird began to speak with the vet says “I’m Mr. Yosuke Nakamura.” He also  provides a complete home address to the last number. Pretty sure he was  right and returned to the house, but not before entertaining the  hospital with a song and dance.
6.. North Pacific Giant Octopus
This  animal live in the depth of the sea. They belong to cephalopods  molluscs class. All types of cephalopods are known to have exceptional  intellectual ability. Octopus is considered the most intelligent  invertebrate life. In the experimental conditions, these animals have  shown short and long term memory. They have an extraordinary observation  learning and problem solving skills. Octopus nervous system has a very  large, but only partially found in their brains. In about two-thirds of  octopus, neurons can be found on the rope around and the arm. There are  arm that has a very large autonomy. They are masters of mimicry and  camouflage. They are professional escape artist and can often be found  in the hull crabs, eat the catch. This animal is very keen eyesight,  sense of touch, and very fast. There was a report from the North Pacific  Giant Octopus that reach 600 pounds, with a range of hands 30 feet.
7. Border Collie
Border  Collie is widely regarded as the most intelligent dog breed in the  world. They usually spend their time tending sheep and cattle handling  various forms, but It’s also a great pet. With physical exercise and  various forms of mental stimulation this dog is the fastest to learn.  The dog is originated in Scotland, Welsh, and English border and the  dogs make a direct impact on the agricultural industry. It has been  reported that in certain areas Australian Outback, a trained collie can  do five times the amount of work that usually done by human. Border  Collie dominate over all breeds in dog sports. They excel in the high  jump, utility classes, flying-ball, and even can take first place in dog  dancing competitions. They have an extraordinary sense of smell and is  widely regarded as the great dog. They can be trained as helper dogs, or  in search and rescue as well. This dog obviously will recognize you as  an individual personality, they will learn your routine, anticipate what  will happen next, and find a way to get what they want.
8. Ravens & Crows
These  two animals is mentioned together because both are members of the  family Corvidae birds. This family is widely regarded as the most  intelligent of all birds. Peak crow IQ scale, which is a scientific test  to determine the intelligence of birds. They can count, distinguish  complex shapes, and perform observational study tasks. Crows are social  creatures and will be involved in the air to form a jousting sequence  power. Wild hooded crows in Israel have learned to use bread crumbs as  bait fish, think in advance and anticipate the catch. The New Caledonian  Crow have been studied for its ability to use tools in looking for food  everyday . This includes creating a knife that cut the leaves and stems  of grass. They are also using advanced picking, smoothing, and bending  of twigs and grass stems to produce a variety of food substances. Raven  is similar to the crow, but larger size. Both species are black and the  main difference is in their vocalizations. Ravens do a lot of the same  behavior as crows, but they have been recognized for their ability to  drop the beans, clams, muscles, and oysters on the highway, waiting for  cars to run them over.
9. Rats
There  are hundreds of species of rats in the whole world. Rat is one of the  most studied and tested the animals on this planet. They have been the  subject of research and experiments for various well-known and  influential physiological studies. The reason for this is that mice is  similar to the psychology of human. All rats learned new behaviors and  tricks easily. A 2007 study found that mice have metacognition, which is  a mental ability previously only been documented in humans and some  primates. Mice have a remarkable sense of smell and hearing. They have  been trained to detect landmines and bombs. Research and latest  technology has been suggested that mice could even smell and identify  human sputum samples infected with TB. This is a wonderful animal to  solve the maze. Rats are social animals and show signs of remorse, joy,  loss, and stress. They dream in a very similar way as humans. They also  demonstrate exceptional organizational and technical maintenance. Just  remember, mice are intelligent and friendly creatures so don’t afraid of  them.
10. Portia Labiata Jumping Spider
This  species is a member of the genus Portia, kind of spiders and smallest  creatures in the list. Also known as the White-whiskered Portia, they  inhabit the critical areas and secondary forests in Africa, Asia, and  Australia. This spider has shown the ability to learn in laboratory  tests and the bug has been labeled the smartest in the world. They  perform surprisingly well in various tasks of solving problems. One of  the principles of their other charming skills of spider webs to their  food. To do this they will pull the rhythm in the corner of the web to  mimic the trapped bug or insect intruders. If Portia had been found of  this spider before, it will remember what the rhythm pattern used to  achieve success. Portia labiata had large eyes and have been seen using  extraordinary instinctive behavior. The spider who planned to use trial  and error approach to hunting and cognitive showed a strong base. When  the prey comes and goes, the spider will sit and wait for hours to have a  perfect moment to strike. Next, plan ahead and understanding that will  eventually eat again. This spider has also shown signs of selective  attention by identifying a particular object and prey on others.
