Dumbest Animals In The World: Turkey

Which Animal has No Brain and Heart? || Which Bird flies at the highest Altitude

One of the dumbest birds, the Turkey, was first domesticated by the Aztecs.

The Meleagris, or turkey, is a beloved food at least once a year. Many enjoy them as pets. And the entire world knows how much the turkey deserves to be on any list of dumbest bird. They have widely-spaced eyes and an almost clumsy, dim-witted walk. Benjamin Franklin called them birds of courage. Animal Planet says theyre confused, while The Washington Post attests these animals are just misunderstood.

Owners who love the bird have spoken of their turkey preferring to only drink water that drips upward. This phenomenon is the result of the bird consuming rain as it falls from the sky. But theyre not drinking. They simply have a tendency of staring into the sky for up to 30 minutes at a time. When it rains, it appears the birds are simply mesmerized at the idea of wetness coming out of nowhere. So, they stare with their mouths open in awe. Often, they do so until they drown.

Similarities Between Human And Animal Brain

The similarities between human brain and animal brain include:

  • The human and the animal brain form a part of the central nervous system.
  • The brain of both are made up of neurons and neuroglia.
  • Its main function is to control thoughts and body movement.
  • The brain of all the vertebrate animals is divided into forebrain, midbrain, cerebellum, hind brain, medulla oblongata and pons.

    Similarities Between Humans And Animals Brain

    • Humans and animals brain are one of the two components of the central nervous system while the second component is the spinal cord.
    • Both occur in the head region of the body.
    • Besides, the brain of the vertebrate animals occurs inside the skull, a cover made up of bones.
    • The brain of both is made up of neurons and supporting cells called neuroglia.
    • Also, the main parts of the vertebrate brain are telencephalon, diencephalon, midbrain, cerebellum, pons, and medulla.
    • Furthermore, the main function of both the brains is to control thoughts, memory, and the movement of the body.

    Dumbest Animals In The World: Ostrich

    The Ostrich, the dumbest animal, will eat absolutely everything!

    The ostrich is one of the largest birds in the world. And its not just the size that makes it stand out. Its a flightless bird with small wings. Other birds that stick to the ground include the emu and the kiwi. The ostrich has a long neck and long legs. The ostrich, primarily roaming the plans of Africa, travels in social groups of up to 50.

    While its argued that this creature has the capacity to show reasonable smarts, what makes it stand out as the dumbest bird is its reaction to threat. The bird is capable of running away and even hiding. The ostrich also can be aggressively defensive, having a serious clawed foot thats killed lions. But when push comes to shove, faced with an imposing threat, the ostrich will push its head at the ground , close its eyes and go invisible. Well, the bird thinks its invisible. Theyre kind of stupid animals.

    Animals With The Shortest Memory

    Suzana Herculano

    You have probably heard that goldfishs memory is no good. It is often used as an example of how bad memory can be. But it is actually a myth. Studies have shown that goldfish can actually remember items for longer periods of time.

    So who in the animal;kingdom has the worst memory?

    This is not something we could find much research about.

    But it seems like most animals have a very bad short-term memory when it comes to events that are not critical to survival.

    According to the Swedish animal specialist Johan Lind at the University of;Stockholm, animals have only around 27 seconds of memory. Thats when we are talking about short-term memory.

    Unless the events in question have any importance related to food or survival the animals could not remember what happened. They seem to only remember casual events when its related to basic survival.

    It seems like humans are the only creature with the memory capacity to remember more than a few minutes.

    Is There Only One Rule To Build Brains

    Even though the parts are the same, this does not mean that brains of the same size are built of the same amounts of each kind of cell. It is also not true that a bigger brain is always made of more cells than a smaller brain.

    We can think about this with an example. Imagine that you receive two brains of the same weight but belonging to different species. This is what we see in Figure 2: a rhesus monkey brain and a capybara brain . Both brains weigh about 80 g. You would probably say the brains have the same number of neuronsand so would many scientists. Until about 10 years ago, most researchers expected brains of the same size to have the same number of neurons. They thought that there was only one recipe in nature for building brains, and that all brains were made the same way. That also meant that the bigger the brain, the more neurons it would have.

    • Figure 2 – Nature has different ways of adding neurons to primate and rodent brains as they change in size from one species to another.
    • This means that when a rodent brain gets larger, it does not gain many neurons. In contrast, when a primate brain gets bigger, its number of neurons grows more or less in proportion to how much larger the brain is.

    Disproportionate Decrease In Brain In Small

    The study examined over 1000 mammals to see how brain-to-body size changed over evolution. In this phylogeny, the different colors indicate groups that have a different brain-to-body relationship.

    Small-brained mammals, however, tell a different story. In contrast to the assortment of evolutionary paths taken by relatively big brained mammals, those near the bottom of the brain-body space, such as golden moles, marsupials, and bats, seem to follow a singular trajectory. One of the surprising trends in smaller brained mammals is that they all show a disproportionate decrease in brain compared to body size, which indicates that theres a limit to how small a body can be, says bat biologist Dina Dechmann, a research scientist at the Max Planck Institute of Animal Behavior and co-author on the study, For bats, which are the only truly flying mammals, this makes sense. Bats are energetically limited, and the brain is very costly to maintain and to carry around in flight. It seems like bats off loaded what they didnt need.

    What Are The Major Differences Between Human And Animal Brains

    Sep 17, 2017 | Health |

    We dont think it comes as a surprise to anyone that there are major differences between the human brain and the brains of animals. Those that follow Darwins Theory of Evolution may say it has to do with the structures of our brains. Then, there are those who believe in the religious view that God created humans in His image and gave us the gift of self-awareness. Since we couldnt decide on just one key distinction, weve compiled a list of the major differences between human and animal brains.

    Corvids Are Surprisingly Smart

    What animal has 32 brains?

    The corvids have surprised scientists with their remarkable memory, their ability to employ complex social reasoning and their capacity to craft and use tools. Mr Bird, who is based at the department of zoology at Cambridge University and is supervised by Dr Nathan Emery, says: I would rate corvids as being as intelligent as primates in many ways.

    The corvids are a group of birds that include: ravens, crows, jackdaws, jays, rooks, and magpies. They are very social birds who have the ability to identify individuals, form alliances and nurture relationships.

    Some Spiders Brains Are Literally Too Big For Their Heads

    Irrespective of the size of the spiders body its brain always remains the same size. All spider species have to perform the same, more or less, basic tasks. Some spider tasks are fairly complex and thus a large portion of their body needs to be occupied by brain cells. Brain cells cannot be too small or they will not function properly, so some spiderling young have to sport bulging bodies just to contain all their brains.

    Smithsonian Tropical Resarch Insitute scientist William Wcislo explains: The smaller the animal, the more it has to invest in its brain, which means even very tiny spiders are able to weave a web and perform other fairly complex behavior. We discovered that the central nervous system of the smallest spiders fill up almost 80 percent of their total body cavity, including about 25 percent of their legs.

    Nature’s 5 Smartest Animal Species


    In a celebrated case a few years ago, an Israeli man was targeted by a local crow in an apparent revenge attack. The bird’s chick fell out of its nest and the man carried it outside of his backyard. It wasn’t long before the crow had him in its eye sights, forcing the man to wear a helmet and carry a parasol for self protection. That kind of intelligence wasn’t a fluke. Take a look at this 2008 talk at the Ted Conference given by Joshua Klein, who showed off an amazing video displaying how crows quickly adapt to their surroundings.

    Like elephants, chimps recognize themselves and have also been observed showing a range of emotions associated with human behavior, such as caring or mourning. Chimpanzes have been documented fashioning sticks into “spears” to hunt smaller primates. They’ve also been observed altering long twigs to fish for termite or using rocks to crack nuts. What’s more, they have been found to cooperate with each other in coming up with sophisticated hunting strategies to kill prey.

    Perhaps not entirely surprising given that chimpanzees happen to be the closest living relatives to humans in the animal kingdom.

    Animals With Multiple Brains

    A creatures brain is a mass of nerve tissue that controls the rest of the body, the majority of animals have one brain. There are, however, several types of animals with multiple brains so to speak.;To clear up the confusion, it depends on how you look at it.

    If you look at it anatomically, all animals have only one brain, but some species have sections known as ganglia, which function independently from the main brain. These ganglia can be split up into many different parts that operate independent of each other.

    If you look at it in this manner, animals with such sections and hemispheres can be categorized as having multiple brains. This is because each ganglion functions autonomously.

    There are several animals with more than one brain. So lets dive right in and have a look at 10 animals with multiple brains, then a few rare cases and couple of honorable mentions.

    Dumbest Animals In The World: Horned Lizard

    Why do humans have higher intelligence than all other ...

    A Mexican Plateau horned lizard . Its horny appearance and coloration helps it to blend into sparse vegetation.

    The horned lizard looks unusual because of its squat, flattened shape and short, blunt snout. While it looks unusual, they appear to be lazy. They have spines on their bodies. They wait for an ant to wander by before they snatch it. Otherwise, they spend their day being lazy in the desert.

    When a horned lizard feels threatened, however, it can shoot blood from its eyes. Their unusual body shape helps ensure that they can get close enough for the blood to reach their predator. The lizards blood can shoot up to 3 feet, deters predators from getting closer, and predators often find out that it tastes horrible. The blood that comes out of a special duct near their eyes is toxic to canines, like dogs, wolves, and coyotes.

    Furthermore, they can inflate their bodies to twice their size. Then, they look like spiny balloons. Therefore, other animals do not want to approach it for fear that they will get poked.

    What Does Brain Size Have To Do With Intelligence

    Very littleeven if it’s very big.

    ByRachel Feltman | Published Mar 15, 2018 7:00 PM


    Researchers used to think brain-to-body-size ratio revealed intelligence because it showed how a species devoted energy to its cranium. They were utterly wrong. Other ratios better predict smarts, but theres still no perfect metric. This ranking, by brain-to-body ratio, shows just how little we know about, well, knowing stuff.

    Dumbest Animals In The World: Cane Toads

    The cane toad, the dumbest amphibian on our list, will eat dog food.

    Found in several locations, including Northern Australia, South America and mainland Central America, cane toads have long been labeled as really stupid animals. The worlds largest toad, it has a diet that includes both living and deceased matter. And that trait goes beyond their meals.

    These aggressive creatures can be found openly having physical relations with anything. Live or dead. Without hesitation, they assault rats, lizards, snakes, and anything else that moves. Obviously, these creatures love physical intimacy, to say the least.

    If its about propagating the species, were confused. The females are extremely fertile. One female is capable of laying nearly 30,000 eggs at the same time.

    Which Animals Have The Strongest Sense Of Smell

    • Recent studies have found that the African elephant has the strongest sense of smell in the animal kingdom.
    • A bloodhound is often referred to as a nose attached to a dog since these pooches have the amazing ability to scan a terrain with their nose.
    • The male silk moth’s large, elaborate, feathery antennae are filled with scent receptors that enable them to sense a single pheromone scent particle from a female more than seven miles away.;

    Humans may be the most intelligent creatures to walk the Earth but other members of the animal kingdom shouldnt be underestimated. Thousands of years of evolution have given them uncanny abilities that allowed their species to survive. These abilities allowed them to hunt for food, avoid predators, or find a mate to ensure the perpetuation of their species.

    Among the most interesting abilities developed by some animals is a superb sense of smell. These super sniffers use their noses to smell a meal from far away or sense danger. Here is a list of creatures with the strongest sense of smell in the animal kingdom.

    Dumbest Animals In The World: Japanese Land Snails

    What Animal Has the Largest Brain?

    Snails live in slow motion. Normally they reach a top speed of 50 yards per hour; this is about 0.5 inches per second

    Most snails hide inside their hard shells until a threat of danger passes. That is not the case with the Japanese land snails as they come out of their shells.

    While that may seem like a move that would easily land them on our stupidest animal ever list, it is a brilliant move. The Ezohelix gainesi snail from Japan and the Karaftohelix selskii from Eastern Russia can throw their shells at their predators. The most common predator of these snails is the beetle. These snails can sling their shells about 180-degrees, and they use it to knock the beetle away.

    The Colossal Squid Eats Through Its Brain

    The colossal squid is the largest known squid on Earth if you go by mass. It has a doughnut shaped brain. The hold in the middle of the brain is quite small but makes room for their esophagus, which runs through the hole. The esophagus has a diameter of around 10 mm . The brain of the squid is not very large weighing approximately 100 grams . A strange and interesting fact about this animal is that they need to tear up its food into very small pieces so that they do not injure their brain when they swallow.

    Strange Brains In The Animal Kingdom

    We may be biased, but we think the human brain is pretty special. All this week, is celebrating this miracle organ with a heap of brain stories, lists, and videos. It all leads up to Brain Surgery Live With mental_floss, a two-hour television event hosted by Bryant Gumbel.;The special airs Sunday, October 25 at 9 p.m. EST on the National Geographic Channel.

    Brain size may not matter, but proportions sure do. Thanks to a biology principle called Hallers Rule, the brains of small animals must take up more room to function. The result? Tiny animals have giant brains for their body size, while larger creatures have hilariously small ones. Ants, for example, are 15 percent brain! Humans? Not even 3 percent. The wacky proportions mean some animals have unusual brainsjust ask these guys.


    The tree shrew is a mystery. Its ratlike but closely related to primates. Scientists have trouble classifying the critter. Even more impressive? It has the highest brain-to-body-mass ratio of any mammal, beating humans.


    At roughly 16 pounds, the sperm whales brain is the biggest on land or in the sea. But dont be fooled. Its pretty measly, considering the whale weighs 50 tons. Most of its head is filled with fatty, yellow tissue called junk.
