Raccoons Pick Locks

If you have a plan for whimsical animal burglary, you will surely want a raccoon to be in your squad. In a bizarre study conducted in 1908 by ethologist H.B. David, raccoons were able to pick complicated locks in less than ten attempts, even after the locks were flipped upside-down or reorganized.

Different studies carried out from the '60s to the '90s discovered that raccoons boast a perfect memory.

Crows Know Physics

Crows can not only identify faces to distinguish between benign and predatory species, but they also know basic physics, have been known to change entire pattern of migration to evade farms where crows have been hunted in the past, and they may even master city garbage routes so that they can catch the food droppings on garbage day. 

Pigs Make Use Of Mirrors

According to a 2015 study from the International Journal of Comparative Psychology, pigs may one day become man's best friend. Just like dogs, pigs have been shown to solve mazes, understand emotions, learn simple symbolic languages, demonstrate empathy and also make best friends which is the most adorable. As one of the smartest animals on Earth, the youngest humans may even be put to shame by our youngest pigs.

Octopus Are Great Escape Artists

Octopus are true prison breakers of the marine. These tentacled animals have shown time and time again their talents for compressing their big bodies through small holes, popping lids off screw-top jars, and impossibly climbing out of aquarium tanks to gain freedom.

Squirrels Perform Tricks

If you have ever had a second thought while trying to remember a password to an online account, just know that you have bowed to sub-squirrel intelligence. According to a study at Princeton University, grey squirrels have the ability to remember where thousands of nuts are laid. 

Dolphins Do Cheat

Dolphins are often seen as the second intelligent animals on the planet as a result of their capacity to show emotion, high brain-to-body size ratio, and remarkable mimicry of the dumb apes who study them. Now, studies from the Mississippi Institute for Marine Mammal Studies advocate that they may also be the second-sneakiest creature on the planet.

Chickens Can Differentiate Between Shapes and Colors

Rats Can Solve Puzzles

Since humans are usually using rats for experiments, you might not see them as the smartest animals. But have you considered that the reason they are used is that they're smart, and can handle the puzzles thrown at them? Rats can master routes even though their eyesight is far.

Pigeons Can Memorize Images

Pigeons are not as "bird-brained" as you might see them. In a German study, 725 random black-and-white pictures were shown to Pigeons one at a time. And the pigeons were able to distinguish between the images in a game that would give most humans trouble. 

African Greys Are as Smart as a Three-Year-Old Child 

Apart from being able to mimic humans, they can also solve puzzles. As stated by Live Science, parrots are as smart as a three-year-old child as they can draw conclusions about where to find food, an ability seen in humans and apes. 

Portia Spiders Make Use Of Trial-and-Error

There are multiple species of Portia, native to Southeast Asia, parts of Africa, and northeastern Australia. They have undeniable intelligence and pose no threat to humans. They are called "eight-legged cats" because of their intelligence-driven and skillful hunting.
