Top 10 Dumbest Animals

The Top Ten
1 Human Humans (Homo sapiens) are the most abundant and widespread species of primate, characterized by bipedalism and large, complex brains. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions... read more

We build only to destroy. Everything we touch gets worse. We print money on trees we need to breath. We eat meat and vegetables while we destroy the ecosystem we need for them to exist. You say cows don't drive? Cars destroy the air we breath and the land we live on. You say sheep don't go to school? School is an institution we use to make people feel as if they know enough, without ever teaching them to question whether what they're told is true. Besides both of the animals you've mentioned we created from wild versions of themselves. They only exist because we use them for our own greed. I would prefer to be a Dolphin or a Grizzly Bear. At least then I'd know my purpose for this planet. The planet would need me to exist for ecosystem I'm apart of to be balanced. Humans have lost their place and are now a self-harming cancerous cell that only continues to destroy everything it will wish for in the future.

2 Sponge

Sponges shouldn't be on this list. They may not have brains, but they don't need them to survive! They actually thrive in most of the world's oceans, with NO brain. Instead, they have developed ingenious ways of living and surviving, and are some of the most diverse creatures on the planet. They can survive in many extremes, like the freezing realm under the snow and ice of Antarctica, and in the deepest parts of the ocean. They are some of the most ancient animals on the PLANET. Being simple animals without a brain, they've survived through millions and millions of years, barely changing, thriving, as other 'smarter' animals died out. That's right, they have survived through many great extinctions, WITHOUT BRAINS.

Sponges are really amazing creatures, you people need to stop judging animals by how 'smart' they are.

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".

3 Amoeba

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

4 Sea Cucumber
5 Jellyfish

Reasons why Jellyfish should move up the list:

People are destructive and make devastating mistakes, but can learn and apply information faster than any other organism. That intelligence can often lead to the first part of the statement.

Sponges deserve to be the #1 dumbest animal. Jellyfish, however, should be #2.

Amoebas aren't really animals...

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.

There is this jellyfish that can turn itself back into a baby when it is going to die of old age. It often gets eaten by a fish afterwards.

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

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

I found a legit 9 legged starfish in Naples, Florida.

7 Sea Urchin

Sea urchins are volleyballs with spikes.

Yes they are just dumb spiky balls!

8 Flatworm
9 Clam

Good enough. Not fully dumb

Nervous system, no brain

Clams are total butts

10 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.

Blobfish lives at depths between 600 and 1,200 m (2,000 and 3,900 ft) where the pressure is 60 to 120 times as great as at sea level.
It only looks like that due to the decompression of its low density flesh, however in its natural habitat, in deep waters it looks like a fish.

You may call them ugly but think of this people call bulldogs ugly but we still love them so show him some love FOR THE BLOBFISH!

It looks like grandpa. My grandpa isn't vary smart. He ate a cow brain or somfing when he was litle. Mommy says to not eat grandpa, because his brain isn't vary god.

The Contenders
11 Dog The dog or domestic dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf, and is characterized by an upturning tail. The dog is derived from an ancient, extinct wolf, and the modern wolf is the dog's nearest living relative. The dog was the first species to be domesticated, by hunter–gatherers over 15,000 years ago, before the development of agriculture. Due... read more

Dogs are by far not the most intelligent animals. Humans are unable to see their limited intelligence simply because of their personal attachments, which are purely instinctive. There are plenty of animals far more intelligent than a dog, whose memories can last them five minutes. They are unable to solve complex cognitive puzzles like a parrot or crow and simply lack the intelligence displayed by even other mammals. Don't let your biases come in the way of reality and the reality is, though no tetrapod should really be on this list, considering there are 2,500 species of coral, dogs do not deserve any sort of high ranking of intelligence, regardless of attachments or your bindings to their cuteness.

I'm voting to defend! (Otherwise I would've probably not voted at all or for the human.) First of all, how are dogs above cats? It's scientifically proven that dogs are smarter than cats! Secondly (while I guess most animals can with training) they can understand human commands easily, with little training! Why do you think on things like T.V. when they have a dog it's real, but when it's a gorilla, is CGI? Third of all, they can understand things that most animals probably couldn't! What I mean is, at one point, we got a no-bark collar that was designed to not hurt the dog but send something out to its system to calm it down, for a dog that wouldn't stop barking! (That's biology.) The dog quickly learned that when the dollar was on, it doesn't bark. But immediately when it was off she knew she could start barking all over again! So, dogs aren't the smartest animals on this planet. Things like apes, elephants, dolphins are technically smarter. But dogs are intelligent creatures nontheless!

12 Turkey

Turkey's are so stupid when they drink rain water as it's falling from the sky they are known to drown because they do not have the common sense to know when to stop drinking which leads to death from drowning. Now I think this bird should make it on the list for dumb animals, don't you?

Turkey's don't drown in the rain. They're not that dumb. What makes them stupid is sex. A Turkey would mate with a 2yr Male turkey. Not to mention one of the toughest livestock to take care of.

I think that truck is on them because whatever people go to hunt they might use a Turkey color and the Turkey one on even know that it's a fake Turkey.

13 Slug
14 Mosquito Spanish for "small fly," mosquitoes are insects 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.

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

They actively seek out humans only to get themselves killed.

They're not dumb. Just annoying.

15 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.

They have no form of defense, gets killed just one bite on the neck by a wild canine, cannot fight at all has make them an unintelligent animal species.

They just stand there all day you have to put the food directly in their face so the eat it if its like 20 ft away they still just stand their. flies go into their eyes and people have to pick them out disgusting right. from that if people didn't pick the bugs they could go blind and get diseases and spread the diseases to other sheep. you have to fight animals who try to eat the sheep because the sheep just stand still and don't blink

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

16 Dodo

If they were not extinct, they could of been chosen to be a house pet since they are not afraid of humans.

I think Dodo birds are the dumbest for sure, they even got extinct because they're so dumb.

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

17 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.

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

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

The only smart thing it can do is know they are in the mirror. Everything else they do is extreme dumbness

18 Sea Slug Sea slug is a common name for some marine invertebrates that more or less resemble terrestrial slugs. Most creatures known as sea slugs are actually snails, i.e.
19 Cow Cattle (Bos taurus) are large, domesticated, cloven-hooved, herbivores. They are a prominent modern member of the subfamily Bovinae and the most widespread species of the genus Bos. Adult females are referred to as cows and adult males are referred to as bulls.

Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which... read more

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.

There smarter then even my cat. I like cats but they sometimes just puss around farting. I think eating a entire cow brain increase your IQ. Cow's brain is so good that they distinguish other cows and even humans as well. Humans can only distinguish other humans

Cows are intelligent and affectionate animals that should be slaughtered in the millions to satisfy people's taste buds and to be forcefully impregnated only to have their calves stolen from them.

20 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 stubborn an ornery but not dumb. They are smart enough to get out of work by being so ornery you would rather move on than keep on... dealing with an ass.

Donkeys are so lazy and stubborn.

Donkeys are awesome...

21 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.

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

Roaches can survive everything. They not be stupid

22 Horse The horse is an odd-toed, hoofed mammal of the taxonomic family Equidae whose sole major subspecies (Equus ferus caballus) is a domesticate, although wild subspecies have survived into the modern period. All subspecies, including the two extant ones, descend from the Pleistocene Equus ferus. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into... read more

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.

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.

23 Tiger The tiger (Panthera tigris) is the largest living cat species and a member of the genus Panthera. It is most recognisable for its dark vertical stripes on orange fur with a white underside. An apex predator, it primarily preys on ungulates such as deer and wild boar. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat, which support its requirements... read more

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 very smart because they can sent danger from far distance.

Tigers are the dumbest big cats. Their big mass had cost them their brain.

24 Cat The cat (Felis catus) is a domestic species of small carnivorous mammal.
It is the only domesticated species in the family Felidae and is often referred to as the domestic cat to distinguish it from the wild members of the family. A cat can either be a house cat, a farm cat or a feral cat; the latter... read more

Cats are really stupid. A lot of the, Do annoying and unfunny things like attempt to jump over things they already know are too far and finna get hurt badly and go to cat hospital. They sleep too much and don't bother to do anything apart from be idiots.

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...

This isn't a top ten but cats are really stupid. They should all just kill themselves so that dogs can be the smarter of the common domestic animal pet list species animals.

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

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 are actually rather smart. Intelligence Isn't based on your brain size, as some of you may think. *Stares judiciously at nearest person*

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