“Intelligent” is not a word that you would use to describe the majority of animals, but humans are not the only species that have smarts. Whilst none are able to match the intelligence of humans, there are many different species, both big and small, that are very impressive when studied closely. They have adapted over millions of years to become intelligent, resourceful, and even crafty so that they are capable of surviving on their own. Several of the animals on this list might be predictable, but there are also a few surprise inclusions which should change your entire perception of the species.
Pigs are often an animal that get a bad name for being smelly and stupid, but this is absolutely not the case. Studies actually show them to be very smart creatures, and about as trainable as dogs. They are excellent scavengers and therefore able to adapt to their surroundings, and often “deceive” each other so that they can get more food. Their communication and social nature is remarkable, and they are always seen together as they seek out the company of one another and attempt to maintain physical contact. The mother pigs are even known to sing to their offspring to calm them. All of this means that their behavior is not like cattle, sheep and other farmyard animals, but instead much more like dogs and even humans. Their social nature and trainability (plus cuteness) sees them sometimes kept as pets.
