Mammals have the most complex nervous system on the planet, with
humans
being the most advanced. The nervous system works with the senses to transmit information to the mammal’s brain, a process that takes less than one-hundredth of a second.
What animal has the most developed brain?
Elephants
have the largest brains of any land animal. The cortex of an elephant’s brain has as many neurons as a human brain. Elephants have exceptional memories, cooperate with each other, and demonstrate self-awareness. Like primates and birds, they engage in play.
Which species has the most complex brain?
We’ve known for a long time that
whales and dolphins
are intelligent and socially complex animals with large brains that are organized differently from our own. And we’ve known that the neocortex of a whale or dolphin brain has more folds than ours.
What is the most complex nervous system?
The brain
is the body’s most complex organ. There are around 86 billion neurons in the human brain, all of which are in use. Each neuron communicates with many other neurons to form circuits and share information. Proper nervous system function involves coordinated action of neurons in many brain regions.
Which animal has the least complicated nervous system?
The only multicellular animals that have no nervous system at all are
sponges and microscopic bloblike organisms
called placozoans and mesozoans. The nervous systems of ctenophores (comb jellies) and cnidarians (e.g., anemones, hydras, corals and jellyfishes) consist of a diffuse nerve net.
What animal has 32 brains?
2.
Leeches
have 32 brains. A leech’s internal structure is divided into 32 separate segments, and each of these segments has its own brain. In addition to that, every leech has nine pairs of testes — but that’s another post for another day.

What is the most complex part of human body?
The brain
is the most complex organ in the human body. It produces our every thought, action, memory, feeling and experience of the world. This jelly-like mass of tissue, weighing in at around 1.4 kilograms, contains a staggering one hundred billion nerve cells, or neurons.
What is the most complex thing in the world?
The brain
is the last and grandest biological frontier, the most complex thing we have yet discovered in our universe. It contains hundreds of billions of cells interlinked through trillions of connections. The brain boggles the mind.
What are the 3 nervous systems?
- The brain and the spinal cord are the central nervous system.
- The nerves that go through the whole body make up the peripheral nervous system.
Which animal has nervous system but no brain?
The animal that has a nervous system but no brains belong to the
phylum Coelenterata class Hydrozoa

What animals Cannot feel pain?
Though it has been argued that most
invertebrates
do not feel pain, there is some evidence that invertebrates, especially the decapod crustaceans (e.g. crabs and lobsters) and cephalopods (e.g. octopuses), exhibit behavioural and physiological reactions indicating they may have the capacity for this experience.
What animal has the least brain cells?
There is one organism that has no brain or nervous tissue of any kind:
