    I would also like to mention that chimpanzees in the wild have been known to medicate themselves. For example, if a chimpanzee has a stomach ache, he knows what plant to eat to make it feel better. In fact, humans have discovered medicinal plants just by observing the chimpanzees. Awesome article!

    • earl

      another biased list, like I said if you think about all of those physical advantages the primates have over the rest of the animals they are the dumbest. What you just said about chimps almost every other animal does it too, if chimps really were the smartest we would see police chimps, soldier chimps, chimps guiding the blind, chimps busting illegal drugs, or swimming underwater with a camcorder getting data, finding missing persons in the woods or using actual human words like some birds to try to communicate with humans

      • Ahmad

        Seriously? how old are you? primates are the most intelligent animals ever to exist, go troll somewhere else on xbox and leave these articles for the elders.

  • Hypoallergenic Dog B

    As for dogs, do you know any reliable resource where one can find all the local dog kennels?

    • jtomblin

      Try the AKC (American Kennel Club)

  • PastTime491

    There are many resources out there on dog kennels, but I am not sure if there is one webpage for all. One popular website where private breeders and kennel clubs post listings is I am not sure what area you are in, but I would suggest searching google for dog kennel and your local city or town. Local pet stores can also be very helpful in referring good and reliable kennels. Hope I helped answer your question. Let me know if you have any more.

  • Holli

    Grrr. Big deal, a chimpanzee can do that. So, if a dolphin wasn't a sea mammal, it could do what the chimp did. I also find it unfair that the cat does have its own number, when the cat is extremely smart. Puhhh.

    • Geno Williams

      Cats Are Smart,But Lack The Physical Ability To Prove How Smart They Can Actually Be.

      • Solomon

        Actually they’re not all that smart, animals with high IQs typically work in teams and communicate effectively. Man is a political animal and so are dogs dolphins and chimps, all of these mammals are extremely simple to train. Cats are not easy to train they are selfish and do not live in communities. What cat lovers call an independent spirit is actually a sign of stupidity – because what anybody with a shred of common sense already knows is that we accomplish more when we work in teams.

        • Soul

          What are you talking about? Cats roam in clans if need be.

        • Believing that animals that possess high levels of intelligence “work in teams” is evidence of solipsism, or indeed the pathetic fallacy. Nonetheless, some species that show high levels of intelligence do but others, such as cats (with the exception of Lions) live largely solitary lives.

          Birds are continually fascinating me with their intelligence.

          Are we really the most intelligent species of animals? What do we mean by intelligence and how does this relate to animals?

        • steve

          I would postulate that evolving as solitary hunters/survivors would force them to be more resourcefull on their own abilitys and not that of the clan/group….thus evolving into a smarter creature.I’m not the first to say this and this is just one of the reasons the list,while interesting is meaningless.A cat is certainly smarter then a spider …although I admit the spider is impressive.

  • carlos

    i think you should've mentioned kea parrots they're quite smart, they can be a pain in the ass as well for people in new zealand

  • Dread

    Where is the pig on here? They are certainly a top 10 smartest animal. I think a more generalized approach would have been wisest when calculating the smartest species. Pigs would have been 4 on my list.

    I don't know if you don't know that they are smart, simply because they are a food source, and most people assume they are st*pid, or not. People eat monkey brains too though, so that's not a valid response. lol

  • Mike

    "rats possess metacognition, which is a mental ability that has previously only been documented in humans and some primates"

    Instead of stating who shares metacognition wouldn't it have been better to say what exactly it is?

    • Kiwidude

      Metacognition is the ability to think about and analyze ones own thinking. Why we think what we do, and what has influenced our thought process.

  • gumby

    So I'm guessing you have humans at number 11?

    • Geno Williams

      Humans??? I Read That This Was A List For Animals,& If You Don’t Realize That Humans Are Not Animals,Maybe You Shouldn’t Be Ranked At All….!!!!

      • SamDooel

        Humans are Animals!

        • Confidential

          Some people doesn’t know that, lol

        • bob

          Humans are not animals. God breathed us into being. We have been to the moon and can send images thousands of miles in a second. We are nothing like animals. The nearest intelligent animal is dumber than a 2 year old human. Anyone who thinks we are animals doesn’t understand.

          • Hugo

            It’s that kinda species-centric arrogance that has seen our earth as sodomized as it is today. We are worse than animals; animals live and act to survive, and usually fulfill some important roll in the ecosystem, we live for greed and self-improvement and offer nothing back to the world but habitat destruction, increasingly acidifying oceans, species extinction, general pollution, etc etc.

          • Steve

            “Humans are not animals. God breathed us into being”

            And there’s your conclusive proof that animals are more intelligent than humans. No animal would believe the same nonsense Bob clearly believes.

            • Richard Dawkins’ friend

              Amen to that! See what I did there? Loool. We are animals. Some of us like bob not including myself are deluded animals.

            • banner


      • Abcdefghijklmnopqrstuvwxyz

        Humans are animals. We live eat drink and breath. We also have hair, proof that we are mammals

      • Steve

        So if we’re not animals we’re…. plants? You have two choices – either we’re animals or we’re plants. All we are is distant relatives of chimps. Nothing more.

    • ratsrock

      Humans are animals but because we have religious people we are downright dumb if you ask me,I feel sorry for their children as they have no room to choose their own faith,

      Rats should be higher in the list and dolphins should be lower ,asthey have evidence to prove that rats are smarter than made out to be and dolphins are dumber

  • Holli

    Cats are some of the smartest animals alive…..why the heck do they not have their own number? Why do they have to share a number with freaking, stupid rats and dogs? Cats are very smart and I think that who ever made this list needs to give them a number by themselves. And a high one at that! >:l

    • zozopaw

      Umm….. dogs are smarter than cats but i agree cats should be on here 🙂

      • Geno Williams

        When You Actually Think About It,It’s Actually A Privilege For Cats &Dogs To Be Numbered With Rats. Look How Much Time Cats & Dogs Spends Around Humans To Be Taught & Learn Things As Opposed To Rats. Rats Adapt,Improvises,Assimilate & Focalize Very Well & Intelligently,All Without Human Dictation!!!! Can You Think About or Even Image The Level of Intelligence Rats Would Ascend To If They Were Part of Humans Trainable Everyday Lives,or Should I Ask Your Cat or Dog This Question???

  • upyours

    why no bonobos?

    • Jools

      Yeah I would've let that slide if they'd just said Chimpanzee but instead they seemed to deliberately select the less intelligent species.

      Also where the hell are the pigs. They're smarter than cats or dogs.

  • Feefle

    No cats, pigs or humans on this list? Most of the animals selected are considered smart because they can perform simple tasks that look cute when an animal does it…

  • anonymous

    Some of the entries here are debatable, but in general, the choices are agreeable. I just thought I'd make one little comment here: that video with the fishing "crow"? Yeah, that's not a crow. That's a heron.

  • marvin nubwaxer

    i knew cats would not be on this list

  • Scott Schafer

    “Monkey’s performed admirably in these competitions, winning with intelligence.”

    This reads like a 5th grader’s science report that was written in a hurry.

    I’m glad that Portia Labiata made the list, and agree that humans should have topped it…since we’re using human standards of intelligence here anyway.

  • Feefle

    dogs are smarter than cats its been studied

  • CC

    It depends on what you mean by “smart”. A cat will not be taught to sit because they find no reason behind it, you can teach a dog but does that really mean they are more clever?
    Look at how a cat approaches obstacles vs a non-trained dog and the cat excels with their own reasoning. At least that is what I have noticed.

    A dolphin is probably the smartest one of all animals imo, but since they are in water and do not have hands I guess they can’t solve the harder ones like the chimp does.

    • bob

      Yes dogs are more clever because they can be taught. Since they can be taught humans like them better and own more of them. And getting humans to like you and give you treats makes you smarter than the animal that doesn’t. For instance I have owned 8 dogs in my lifetime. I will never own a cat. They are snobby, wont come when called and won’t love you unless its on their own time. Hell they don’t even warn you if someones breaking in. At least the dog will bark and protect you. The cat will run under the bed and let you die then eat you after ward.

  • Only

    The dolphins should be number one, it is supposed that they are nearly as smart as humans.

  • Iamnumber1

    Orca should be #4…How do you have a spider, a dog, and a parrot over a killer whale?

    • Confidential

      Orcas are the largest dolphins, so, in this top, they are also on 2nd place. However, scientists have said that dolphins are actually the most inteligent creatures on Earth. Some of them also say they are even more inteligent than humans.

      You see, if a bomb destroy every build and machine humans have created this far, the human race would disappear in a few years, because we can´t survive withouth artificial things, unlike the other animals

      • Alex

        The fact that we can argue over whether or not we are the smartest animals on Earth proves that we are.

  • fizx

    Humans should be ranked #1 on this list.

  • Andrew Smith

    i just like the way how octopuses thinks!

  • Carlos Morgado

    how can homo sapien not be number one? what you don’t think we are animals?

    • Confidential

      Well, yes!
      If we are not animals, so what are we? Plants? Fungus perhaps?
      If you don’t know, humans are animals just like any other. I know, it is embarrassing. But some years ago, scientists decided that Homo sapiens is just another one.

      The only diference between us and other animals, is that we have thumbs which allow us to build houses and machines…. and also destroy the environment just for pleasure and good life.

      For us, tecnology is synonym of inteligence, although it is not. It is rare the person who can survive without a weapon or any other tool.
      The humans accustomed to the benefits of technologies so much, that if we lost it, we would have difficulty to survive, even in our natural habitat (African savannas).

      • Geno Williams

        If That’s Your Only Difference Between Animals & Humans,Them I Agree With You…..You Are Embarrassing & A Plant!!!!!

    • steve

      We are geneticly inhanced ….at least that is my suspicion…how is it we have such a high intelligence?We can design complex algorithems ,calculate space travel etc…..evolution alone does not explain this.Any fool can see that….come on how is that level of intellect necessary for survival in a forest of jungle? Obviously its not. So where did we get this added intelligence and why?

  • Bob loblaw

    No mention of bears at all?


  • nido

    I don’t trust this list completely, I mean in the elephants’ description, it added that they’re capable of artistic abilities. The elephants that paint in carnivals are not actually painting! There’s a person that tugs on the elephant’s ear to make the elephant paint in the direction its ear is pulled. Seems like these people need to do their research before posting false facts.

  • blues

    I just wonder why a dog isn’t even mentioned!

    My dog is very clever and it shows emotions. Is a cow more intelligent than a dog? No, I can’t believe it.

    We come to a conclusion that we eat intelligent animals… weird.

    • Outerspace

      The Border Collie is listed as #7…since it is considered the “smartest” of all dog breeds, they decided to use it as an example of a dogs intelligence. Different breeds have different levels of IQ’s just like humans.

  • morethanicecream

    I didn’t know that chimps have an excellent mind. They think so fast. I think that we are smarter than them at some things, and they are better than us at some things. If we weren’t surrounded by technology so often and try to gain more knowledge, maybe our brains would be able to get instant memory. I highly doubt that though. I think that this list is too broad. Smart covers about 100 categories. They should have categories for top 10 smartest animals that can talk, top 10 animals with best memory.

    • Geno Williams

      How Many Other Animals Do You Know Off That Dose That? Remember They Are Talking About Animal “Artistic’s” & Not Human!!!!

  • Ronald Mcloughlin

    What abt bonobos? I read once that chimps are aggressive, violent and cannibalistic; whereas bonobos are more emotionally connective and lovable.

  • KittyFreak

    I think cats are at least 5th smartest.

  • Jared

    Humans are not animals. We have a conciousness, and a spirit, and no other animals have this. And there’s even science behind it!

    Evolution is wrong.

    • Ric


      Watch some documentaries first. Where’s the science behind that? Oh well… it was discovered that humans are not the only animal in the world with self-awareness… something that for long was tought to be a unique ability. That is science! Not religion which is only a story and has absolutely no evidences to be truth, unlike the theory of evolution that has been studied and confirmed, and each year that passes, new discoveries are found.

      And if we’re not animals, then why do we have to eat, drink, sleep, why do we die and give birth, why do we get sick, etc, etc, etc….?

      • Of course we are animals. However, whereas the theory of evolution sounds very likely I wouldn’t like to say it has been confirmed! How do you confirm a theory?

  • Outerspace

    I don’t know why so many are insisting that humans should have been listed as #1? Or why this turned into a debate on the theory of evolution. We already know that we have the highest intelligence of all animals (from Latin, the word animal is based on Latin animalis ‘having breath’). I found this article because I was looking for a list of animals that are considered as having high IQ’s and ordered by level of intelligence with examples of what the animal is capable of. This article provided all of that with informative paragraphs for each one and added videos of the animals displaying their abilities. If the article had listed Homo sapiens as the #1 animal with the highest IQ of any other living creature and provided a paragraph of the things we are capable of doing as well as a video with a human demonstrating these things, I would have found it ridiculous! Who was looking for an article like that? I doubt anybody was….

  • X-29

    The list is outdated… everyone knows that pigs are smarter than dogs (and any other domestic animal), an insect will never be smarter than a mammal, dolphins are already ranked at first place since 2010 (second if we count with humans), chimps are almost loosing their “title” for elephants (not yet I think), and…. where is the bear which is believed to have an inteligence level similar to the chimpazee?

  • emmalo

    I was thinking why the controversy over this rating…Hmm,but if you thinks some animals are smarter than humans,may be,somebody should bring them here to defend themselves.Simple!

  • What about Whales (other than Dolphins), Ants or Bees? Bees dancing to show the exact location of flowers in relation to the Sun sounds pretty intelligent to me! I don’t think humans can do that!

  • platypuss

    this is bugging me bad. Mussels. Not muscles.

    • Oh, that is embarrassing. Thanks for catching it.

  • Jack

    I feel uncomfortable reading a list of smartest animals that is deduced by how near they approach human thinking without seeing humans listed as number one. I know it’s obvious so they left out humans but this kind of classification shouldn’t be acceptable because we have children and even some adults that don’t realize humans are an animal species.

  • Mauri Dare

    Why the homo sapiens is not in this list?They are really smart animals.
