No. Whilst most animals have a brain, there are many that only have a small central nervous system that has no real locus that could be called a brain. Single celled organisms are a prime example as are some microscopic marine life. There are also animals that have no central nervous systems, such as oysters, and some that have no nervous systems at all. All mammals have a brain however.
Yes, cats have brains, but not as we know them. Cats can remember thousands of things. Cats are extremly intelligent. They don't exactly have brains they are called brauns pronounced 'br-or-ns' yes, like the electrical company!
No. Most do but not every animal does. Star fish, jellyfish and sponges do not have brains. The nervous system of the starfish is very simple, there is no brain, the nervous system is characterized by a nerve ring that surrounds the mouth. The nervous system of the the jellyfish is characterized by a series of interconnected nerve cells (a nerve net).
I myself reckon so, they all want to provide for the young ones even if they dont work they still find a way to look after their children
They do what humans do just not as extreme. Behaviors, depend by our life forms bodily feeling; where intuition not know to reckon about a smile: of FORGIVENESS within TIME! In front of a THINKER shines more Within his vin to %!!
No. There are animals without brains, too. Examples include bivalves, jellyfish and sponges, the latter of which has absolutely no central nervous system at all.
It depends on which animal you're talking about.
Mammals, reptiles and fish have brains. Bivalves, corals and sponges do not.
It depends on which animal. All mammals, reptiles, and fish have brains. However, their brains are different from each other. Several animals don't even have brains at all.
ant, bugs,big animals and diffrent animals exept jellyfish.
No
no
No, of course not, like humans, animals have a percentage of their brain, no matter how small, that they don't use.
A jellyfish & a starfish A Jellyfish has no brain & no heart A starfish has no brain & no blood
When going from lower to higher animals a larger proportion of the brain is devoted to the cerebrum. The brain stem is made up of medulla and the cerebellum.
Well they say that animals are smarter than humans... so wht doesnt a brain do for a rabbit? here's a question....... wht the heck does a brain do for you?
Mice that are trying to Take over the world
no animals have a brain even dinosaurs do

Both animals and humans do have reward centers in the brain. Both humans and animals feel happy or pleasure when the reward centers of the brain are stimulated.
no
cockroaches
One different is the human have a larger neocortex than a animals.Also,the convolutions resulting in gryi and sulci in the human brain is sometimes not seen in a lower animals or is less complex.
My brain lets me speak and form sentences.
No, of course not, like humans, animals have a percentage of their brain, no matter how small, that they don't use.
Some animals, such as those in the genus Hydra, don't actually have a brain per se, making it difficult to answer.
No, not every animal needs a brain. A jellyfish does not have a brain, it barely has any organs.
Microscopic animals
No.
