Top 10 Dumbest Animals


The Top Ten

1 Human Human Humans are not exactly wild animals, but they are not domesticated either. Humans are proven to be the most intelligent species of animals on Earth. Humans' colours vary from almost pepper black to milky white.

Only an organism as stupid as humans would collectively shun its own capacity for intelligence and ingenuity in favor of entertainment and laziness, would allow itself to invent and subscribe to the concept of racial differences within its own species in order to justify violence, would actively try to kill other members of the same species instead of finding a way to meet everyone's basic needs, would continue to breed when living in a situation where it has not the resources to survive, would invent religion as another means to justify violence against other members of the species, would favor greed over truth, would collectively look the other way when its own species was responsible for actively destroying the only feasible home it has within several digits of light years, would angrily and aggressively defend its decisions to do these things even when evidence of how foolish they are is presented, would become so fearful of potentially being wrong and having to grow and change ...more

Because we are smarter then the other animals

Its funny because we are somehow the dumbest animal but still the smartest I guess it matters what type of person you are talking about

Some are really dumb but some are really smart

2 Sponge

Not even an animal... HAHA I GET IT! One of the humans made this since the humans are #1 lol

I think it's dumb to put humans over this because, if we weren't smart, we wouldn't be the dominant species on earth.

Dumbest is synonym of unintelligent, not inactive or vegetative... A sponge is not "dumb", it can't even show any form of intelligence. So how could it be the animals with a low intelligence?

Yeah in definition it's an animal, but if we start including those who can't "think" or do anything more than what their handful neurons can make them do (like insect) it will never end.

Otherwise we could add sea cucumber, krill, any individual insect, jellyfish, etc. without even knowing which one is the dumbest: there's even no way to measure their intelligence at that level... if we can barely call it "intelligence". - jonathan117

What do sea sponges do that can be smart in fact they should not be on this list because they do not even technically show any sign of intelligence so we can't really say that they show any sign of intelligence, so how could we even call them dumb?

3 Amoeba

Amoebas are protists so yeah, they can't dab or fap.

Amoeba is a plant, it can't do simple things animals do like dab, run around or fap. - AlphaQ

4 Jellyfish

No wonder it has no brain

Jellyfish sting people booty ouchie - AlphaQ

There just blobs of jelly-like skin and are so dumb that it does not have a brain, being controlled only by muscles. Because of this, they don't have set instincts or thinking.

no brain

5 Sea Urchin

Sea urchins are volleyballs with spikes. - AlphaQ

Yes they are just dumb spiky balls!

Sea urchin is just a spiky ball basically


6 Starfish Starfish Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea. Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or "basket stars".

Starfish is patrick. Think of Patrick the stone water boi. - AlphaQ

Now I see why Patrick is a starfish

Starfish Don't even have brains and one of the dumbest animals on earth

Starfish are just random stars that, of course, have no brains, but they are pretty colorful sometimes.

7 Blobfish Blobfish The blobfish is a deep sea fish of the family Psychrolutidae. It inhabits the deep waters off the coasts of mainland Australia and Tasmania, as well as the waters of New Zealand.

They are so sexy. - RoseWeasley

Hey that looks like my brother by the way call me nice buns

How dare you. They are sexy. - AlphaQ

Most misunderstooding animal? - Userguy44

8 Clam

Good enough. Not fully dumb

I love clams they so tasty

They are stupid an a rock

Clams are total butts

9 Dog Dog The domestic dog is a wolf-like canid in the genus Canis, and is the most widely abundant terrestrial carnivore.

Though dog's are smart enough to be trained, they are still not capable of living without humans. Many people think these dogs are very smart but some are attached to their owner that they are not able to live without him/her.

My dog is an idiot

Dogs are packed with a to of Intelligence. If this was on the list, I would still be against this, since this is not true!

They have a five minute memory and cannot live without humans. That makes them a dumb animal who cannot adapt to change. They also kill babies and frail elders.

10 Turkey

Wild turkeys are pretty smart but farm turkeys make me Karen Smith look like Albert Einstein. - RoseWeasley

Wild turkeys? Nope. Farm turkeys? Definitely. Farm turkeys are very stupid, they die form literally drinking rain water and get Super scared of paper airplanes. Jeez, if I threw a paper airplane at someone they wouldn't be scared lol. - AlphaQ

Htis list is dumb why would you put humans number one?

Wild turkeys are extremely intelligent but a farm turkey would drown in rain


The Contenders

11 Pandas

It's panda hunting season

I don't care what anyone says, they are adorable and to the person who said the mom kills the child, they are capable of NOT killing them you know. And if bamboo is the source of their stupidity, how can you blame them for what they like eating. It is like people. If you like cheeseburgers, then that makes you fat. Don't eat them. But you like them right? Exactly

They may be adorable, but they're not for brains. Their energy level is often so low that they can barely reproduce, and often can't recognize their own young. There's a good chance the mother will accidentally murder her newborn by rolling over on them, which makes it unsurprising that they're endangered. We should still try to save the species, but pandas aren't helping out very much. - Emberflight_of_StormClan

I got broads in Atlanta. - AlphaQ

12 Sheep Sheep The sheep is a quadrupedal, ruminant mammal typically kept as livestock. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates.

Incredibly intelligent creatures

Hey! I have a sheep how dare you put sheeps on this list - Mranonymously

Dumb bloody sheep

Sheep actually are quite intelligent. Researchers have found that they have very good memories.

13 Mosquito Mosquito Spanish for "small fly," mosquitoes are flies that have been known to cause various diseases . A sample of diseases caused by mosquitoes: malaria, yellow fever, Chikungunya, West Nile virus, dengue fever, filariasis, Zika virus .

They're not dumb. Just annoying. - Userguy44

Tell your children, every time you kill one an angle will gets its wings.

Mosquitos are annoying little pesky insects

They actively seek out humans only to get themselves killed.

14 Dodo

They are not dumb... They are just friendly and they where not afraid of humans.

They just didn't know people were about to shoot them like if a person pointed a waffle at you you would not to anything plus they can't fly well and we're slow

There not dumb they couldn't fly away from the people

Dodos are extinct, right? Correct me if I'm wrong. - AllAboutLists

15 Chicken Chicken The chicken is a type of domesticated fowl, a subspecies of the red junglefowl. It is one of the most common and widespread domestic animals, with a population of more than 19 billion as of 2011.

All they do is peck eat drink and lay eggs

They’re actually very smart! They can recognize the faces of many other chickens and human faces! - RoseWeasley

I'm only voting so that I can say that chickens learn math faster than humans... newborns can count to 5...

I have chickens and they are pretty inteligent how dare you put chickens on this list - Mranonymously

16 Donkey Donkey The donkey or ass is a domesticated member of the horse family, Equidae. The wild ancestor of the donkey is the African wild ass, E. africanus. The donkey has been used as a working animal for at least 5000 years.

Donkeys are awesome...

Donkeys are so lazy and stubborn.

Donkeys are extremely intelligent they have very good memories

That is not true donkeys are smart

17 Cow Cow Cattle—colloquially cows—are the most common type of large domesticated ungulates. They are a prominent modern member of the subfamily Bovinae, are the most widespread species of the genus Bos, and are most commonly classified collectively as Bos taurus.

Cows are smarter than horses where barbed wire fences are concerned. I have on more than a few occasions witnessed a horse run full force into a barbed wire fence get tangled and rip itself to shreds trying to escape. On the other hand, I have watched a cow in the same situation stop moving and stand there until they could extricate themselves without further injury. This would be one of the reasons horses should be pastured using board or equivalent fencing and never barbed wire.

Cows are actually really smart. They can feel a wide variety of emotions, can open difficult gates and can even worry about the future

They're smarter than sheeps. - Userguy44

They be smarter than a lot of things

18 Horse Horse The horse is one of two extant subspecies of Equus ferus. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae, and can be tamed, bred, and trained, as a mount.

They're walleyed, and will eat until they die if they get hold of an unlimited food source. They stand around in their own poop, and are too dumb to destinguish a slight breeze from a grizzly bear, resulting in the majestic beast throwing their unfortunate rider/food source from their backs in the process of saving their own skins. They lack intelligence on all levels. The seemingly deep and tear-filled look in their eyes is not the result of their mourning for freedom and the love of man. They're just to dumb to blink, and it irritates their big stupid eyes.

Umm NO this is commonly believed by many people that horses are dumb but I have been around horses for about three years and I would know horses are very intelligent in fact they have even been said to have better memory than elephants and do you realize these animals have been used for centurys? Yeah horses are very intelligent so whoever put horses on this list has never been around horses.

Horses aren't stupid. They're very useful because they're fast. Before cars, horses were the only transportation, and they are really fast. When one rides a horse, that person is like a medieval hero or a western defender with true grit like Rooster Cogburn. I myself would just love to ride a fast horse. I imagine myself doing it while I hear the song Wanted Dead or Alive by Bon Jovi in the background.

Horses are my favorite animal and they are very smart and they are dangers and it takes them a long time to learn but they are very kind sweet and they can hurt you but the are very harmful and once you get to know them you will under stand that they don't like to hurt you. people hurt them to make them hurt you I know a lot about them and they don't deserve to be treated like that.

19 Roach

Roach's are actually extremely intelligent. They have been known to swarm Mexicans at a moment's notice. As displayed in Sigmund Freud's 2013 article, "The Roach's are the Mostest", he detailed how they are taking over the world's economy. We need to build a wall before the roaches come for us.

If they're so dumb why can't I kill the damn things.

Every time I see a Roach I just sweep it out of the door or sometimes capture them in a tissue and put them in the garbage bin

Cockroaches are so so goodly intelligent. You don't deserve to make this list

20 Tiger Tiger The tiger is the largest cat species, most recognizable for their pattern of dark vertical stripes on reddish-orange fur with a lighter underside.

Untrue. Tigers are intelligent. - Userguy44

Tigers aren't stupid. They are the mightiest cats of the wild. They're the cat kings. They're fierce, fast, agile, and strong. I consider a tiger as my inner animal. They are at the top of the food chain.

Tigers are extremely smart and they are apex predators that hunt the best way

Tigers are very smart because they can sent danger from far distance.

21 Cat Cat The "House Cat", also known as the Domestic Cat or the Feral Cat, is a small feline, a good hunter, and comes in a variety of colors and fur patterns. Contrary to popular belief, however, they are not truly domesticated. They are highly intelligent and good at problem solving.

They only respond to threat, prey, or convenience. Not sure how impressive that is. They don't respond to most social cues and even make prey of unnecessary creatures and objects...

How are cats not in the top ten, I can never trust people on this site to rate things intelligently, go figure!

They chase light for goodness sake!

Cats run away from a cucumber and jumping into doors they get scared of the random objects - Toptenanimallovers

22 Ant Ant Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera.

I thought ants are smart. - AlphaQ

Ants may be small but it does not mean they are not intelligent.

Complex society =/= intelligence. Individual ants aren't very intelligent at all. There's a reason it's so easy to trap them and trick them.

Ants have the most socially complex brains, in the animal kingdom.

23 Ostrich Ostrich The ostrich or common ostrich is either of two species of large flightless birds native to Africa, the only living member of the genus Struthio, which is in the ratite family. In 2014, the Somali ostrich was recognized as a distinct species.

Ostriches are not very smart it's just thAt the putting their head in the sand is a myth.

They actually do not smash their heads in sand

I think so because when they hid ether pit there head in a hole and when they can't see anything they think no one can see them

Dude that is a myth, I think the ostrich might be smarter (than you) - ILOVEANIMALS

Ostriches have a funny rep to be dumb because their eyes are bigger than their brain

24 Koala Koala The koala is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats.

Koalas have primitive, smooth, and proportionately small brains. A koala only knows routine and cannot use logic to perform tasks that deviate from its normal routine (such as eating leaves off of a plate). They are not a creature of thought, especially considering that they sleep through most of the day...

Recent reacher and studies have discoverd that Koalas are the dumbest and least successful mammal on Earth. While not the dumbest animal, it is the dumbest mammal, It is so dumb that it's possible that there average IQ category is Idiot (0-29 IQ points), it's brain is only 2 percent of there body weight, the smallest brain-to-body ratio, it's brain is also extremely smooth even smoother then a human with Alzheimer desease. A smooth brain in evolutionary slang means a extremely dumb animal and Koalas are also stupid enough that it cannot distinguish a real tree from a drawing or painting of a tree, it's also stupid enough that it won't eat food that's on a plate as there definition of food is that: Food is green things on a bark or a tree. The leaves that they eat are very low in nutrient and not even edible and are very poisonous, as a result they have Immune systems dedicated to prevent the individual Koala to die while eating it. This combine with the thing above makes Koalas the ...more

One of the dumbest animals who show a form of intelligence, even if it's one of the lowest
(contrary to sponge or individual insect who can't even be considered dumb since they don't have any form of intelligence).

-Take a leaf, which he was about to reach for consumption, in a tree and put it in a plate. He won't be able to know what to do with that leaf: he can't figure out that it is still food.

-Low intelligence because of their smooth brain. - jonathan117

Koalas are so stupid that they needed to develop immunity to the leaves they eat, because they are too stupid to know not to eat them.

25 Snail Snail Snail is a common name that is applied most often to land snails, terrestrial pulmonate gastropod molluscs.

Why people being so mean to the snails? I mean they not may smart but they smarter than turkeys or sloths.

Actually, their shell is their for a reason. You are thinking bout slugs

They can't even go fast. Any animal could eat them.

Snails are stupid

26 Guinea Pigs Guinea Pigs The guinea pig, also called the cavy or domestic guinea pig, is a species of rodent belonging to the family Caviidae and the genus Cavia.

Dumbest animals on Earth! They make plants and fungi look like complex intellectual organisms by comparison! All they do is whine, eat until they pop, and poop an pee all over the place! I saw a video were a Guinea pig was in a boa's tank for quite a while and it didn't even notice the danger until the snake killed that little sucker! Dumbest, things, ever!

Guys, maybe Guinea pigs are just a tiny bit dumb but smarter than people think in fact I think they are as smart as mice, take it from a Guinea pig owner.

Guinea pigs are VERY cute and fun! But... They are not the smartest. I don't hate them or dislike them! They just, well, are not the brightest light bulb in the room.

Sorry folks but THIS is why they test guinea pigs

27 Velociraptor Velociraptor Velociraptor is a genus of dromaeosaurid theropod dinosaur that lived approximately 75 to 71 million years ago during the later part of the Cretaceous Period.

Ummm… Velociraptors are dead. correct me if I'm wrong but that would kinda mean there stupid. however on the other hand, when inspected more closely the velociraptor's hunting techniques and close knit families meant that they had more intelligence then any other animal alive in their time period. (Unless your talking about Jurassic park)

Dude, they were one of the smartest dinosaurs

Velociraptors were as smart as a rabbit that's smart from a dinosaur just not smart overall

Dude they are smart assessment. - AlphaQ

28 Goat Goat The domestic goat is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe.

No goats are scientifically proven to be very smart in fact they have gone through test and have been known to be smart enough to know what each light switch can do.

Who ever voted for this (besides me) are the dumbest in the world. Goats are gods. GODS!

They are so dumb. If you come toward them at all, they automatically think you brought them food. You reach out of touch them? They think you're giving them food. They see a fence? They must headbutt it. They also make a dumb noise. They literally sound like they are puking or burping, it is so weird.

True very true

29 Owl Owl Owls are birds from the order Strigiformes, which includes about two hundred species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight.

Guys, you know how it goes that owls are the wisest among animals? Well sorry for you owl lovers but they are not actually very smart, for a long time people have thought they were very wise animals but, according to some study's they have actually been proven to be very dumb birds and one of the dumbest animals for that matter, so now you know, myth busted

Owls aren't stupid. If they were, then Harry Potter wouldn't get Hedwig. I say that Snowy Owls are the most useful owls in the USA and in the United Kingdom.

Hate to break it to you, but owls are the dumbest bird of prey. Look it up

Owl are smart because they have night vision and they now how to live in the wild.

30 Monkey Monkey Monkeys are haplorhine primates, a paraphyletic group generally possessing tails and consisting of approximately 260 known living species.

Hey what is really dumb is this list they literally put the most intelligent animals in the world! Humans Dogs and chickens

Primates like monkeys aren't stupid. If they were, Tarzan wouldn't be a mighty jungle hero and King Kong wouldn't be the world's fiercest ape.

Dude, monkeys are the second smartest thing on earth

Monkeys are smart

31 Pig Pig A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig and its ancestor, the common Eurasian wild boar, along with other species; related creatures outside the genus include the peccary, the babirusa, and the warthog.

Nope guys this is totally wrong pigs are actually VERY intelligent and according to some study's they have been found to be as intelligent as dolphins and 3 year old human children so guys just do more study before putting animals in the "Dumb" category.

"Then Napoleon had an idea. He would destroy the rest of the animals by getting a whole army of disgusting furries. When he assembled it, he attacked the rest of the farm the next morning, including his fellow pigs. Luckily, the rest of the animals drove the furries out and imprisoned Napoleon..." - MarkTheFox

Pigs are some of the stupidest animals I've ever met, and this is from someone who worked at a pig farm. If a pig sees an opening no matter how big, it thinks it can fit through it.

Pigs are very intelligent. They try to fit through because they're just trying to get our any way they can. - InfinateSuperstorm

Pigs almost can be smart as chimpanzees and others! Well, you can say they have a poor eye sight, but they are clever as anything!

1. They can play video games.
2. They have been known to save people’s lives.
3. They are smarter than dogs. - RoseWeasley

32 Goldfish

They are cute but they can't even find the food I put in their pond =-=

33 Fly

Okay guys all animals are smart (Accept Humans) so leave them alone

They can see everywhere, meaning they need big vision receptors

Okay most people don't know this but flies have been found to be very smart! In fact scientist have looked under magnifieing glasses and say them finding really cool strategys to fight off other insects like ninja bugs!

Thesse flys are acualy vary smart! I tryed to kill won the other day, and it just fly away from me! How dos it do it?

34 Lion Lion The lion is one of the big cats in the genus Panthera and a member of the family Felidae. The commonly used term African lion collectively denotes the several subspecies in Africa.

Oh so you're basing this on The Lion King?

Just because of Simba?

Lions are smart

Dumb animals

35 Crow

Really! Crows put dry/stale bread in water to make it easier to eat. come on you have got to be kidding me.

Crow can remember people’s faces

Crows are actually very intelligent,

What!?! They're the smartest birds on Earth!

36 Black Rain Frog Black Rain Frog

dumb face

37 Spiders Spiders

I think that spider is "stupidly" large

38 Mole

Your a mole

39 Earthworm

Earthworms are smart, if you think about it, can't a earthworm hear a mole digging, and a bird pecking the ground?

All they do is eat dirt

Tell me why they are smarter than the humans or the dogs, what they do? Digging like a blind as the moose and that's all you can say so? The ants is wayyy smarter than all thoes disgusting naked bugs.

40 Bear Bear Bears are mammals of the family Ursidae. Bears are classified as caniforms, or doglike carnivorans, with the pinnipeds being their closest living relatives.

Well, wolves kill for fun too. As for how intelligent bears are, the average bear is more intelligent than you think. Bears are not nearly as intelligent as humans, but they're still pretty smart. Scary and dangerous, but smarter than most people think.

Just because they are bad or kill things, how are they dumb? They can just stand from the water and fish some food, that's a technic/strategy?! They now how to get honey safely from bees. Baby bear cubs run up trees to get away from threats. COM'ON PEOPLE!

Dude just look on the Internet these animals are extremely intelligent, no joke it's just amazing

Bears are very bad animals and they are very dumbest animal and they need to be killed good bye bears I don't like the

41 Cane Toad

Studies have shown that the cane toad might be one of the least intelligent vertebrates on Earth. - Emberflight_of_StormClan

42 Cape Buffalo Cape Buffalo The African buffalo or Cape buffalo is a large African bovine. Syncerus caffer caffer, the Cape buffalo, is the typical subspecies, and the largest one, found in Southern and East Africa.

Don't get me wrong, I like buffaloes and I like all other animals as well. But they're pretty dumb. I've seen a video where a crocodile grabs a buffalo by its cheek and the other buffaloes just stare and watch the other poor buffalo dragging the crocodile outside the water until it lets go. So yea. by the way this list is dumb and the people here.

43 Lemming Lemming

How is this not number 1? If one lemming from a pack jumps off a cliff, the rest would run over and jump off, too. - FirstOrder101

44 Polar Bear Polar Bear The polar bear is a carnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses.

So wrong this list is junk

45 Mule

Mule are not dumb, they know their limits better than horses. - Toshin

46 Giant Panda

Eats bamboo when it's a carnivore. This gives it low nutrients so it has a low sex drive.. Oh they also live in mountainous regions then travel to the base to eat the bamboo then climb back up. Can only get pregnant 3 days in a year. Mother's could care less about their babies, too.

They have the digestive system of a carnivore, but they only eat bamboo.

They either roll over their babies, try to kill the crying cubs, or only take one of them in. - Goatworlds

I think pandas are cute..

47 Red Panda Red Panda The red panda (Ailurus fulgens), or also known as the red bear-cat or the red cat-bear, is a mammal native to the Eastern Himalayas and Southwestern China. Despite having the word "panda" in its name, it's not a panda. It's closely related to raccoons

Leave the pandas alone! I bet you look like one anyway... I am only 9 and I know this

Any god fearing gun using varmint should have the right to bear panda bears

They abuse their babies!

48 Louse
49 Armadillo Armadillo

That is totally a real armadillo.

50 Wasps Wasps

This list is DUMB - Mranonymously

Wasps are not only annoying and scary, but they are also very unintelligent. They will sting windows for absolutely no reason, and if you open a door to let it out, it will either ignore the easy way out, or not notice.
