Squids

Squids are said to be among the brainiest invertebrates in the world. Their brain structure is different from other invertebrates in the ocean, as they share complex features similar to the human brain. Like human beings, squids can be very curious about their environment.

Spiders

Spiders are among the smallest creatures to possess a proportionately high level of  intelligence. Especially the White-Mustached Portia spiders. These spiders dwell African; Asian; and Australian forests and have demonstrated special learning skills.

Ants

Ants are often seen coordinating in massive groups to build nests and hunt for food; and they accommodate to their environment very well. All notable points when it comes to measuring intelligence.

Baboons

Baboons are old world monkeys who have cognitive abilities very similar to chimpanzees and orangutans. In terms of the way they behave, one can see how these creatures resemble people. Unlike other animals, studies show that at some level baboons know how to identify stress and cope with it. They create extremely complex social systems and can think critically when confronted with difficult situations.

Sea Lions

Studies have shown that sea lions possess the ability to think logically and can actually deduce if a=b and b=c, then a=c.

Orangutans

Just chimpanzees, the intelligence of orangutans is reflected in the way they imitate human actions. They also have the unique ability to learn complicated new skills, such as sawing wood or using a hammer and nail to put things together. Orangutans have the ability to understand their surroundings in a more abstract way than other animals so they know how to acclimate to some very harsh environments.

Pigeons

There’s a reason why pigeons have been used numerous times throughout history on places like battle fields .  They are extremely good at Geo location and studies have shown that they have an amazing ability to remember people and places throughout the course of their life.

Crows

Along with pigeons, crows are among the most intelligent birds in the world. They have the ability to solve complicated problems and adapt to tough situations which can easilybe seen in the way they gather their food and collect resources.

Sheep

Of all the animals, sheep are believed to possess the most powerful memories with some research showing them to be better than humans in certain situations. For example, they have the ability to identify when a fellow sheep is lost in their flock.  Moreover, they exhibit a wide range of emotions and response to various things going on around them which also shows a high level of intelligence.

Raccoons

Known for being resourceful; raccoons are capable of forming complex social relationships and also make use of complex tools when problem solving.
