What animal has the simplest brain
Instead of a brain, hydra have the most basic nervous system in nature, a nerve net in which neurons spread throughout its body. Even so, researchers still know almost nothing about how the hydra's few thousand neurons interact to create behaviour.
Which animal has most brains
The octopus has 9 brains, one for each tentacle and one at the head. The main brain resides at the head while the other brains are interconnected as fused ganglia, with each brain having its own set of neurons. With more than 500 million neurons, only 30 percent of them are located at its main brain.

What is the smallest brain in the world
nematode worm C.elegans
A model of Einstein's brain is included in the exhibition and there is footage of the world's smallest known brain – the nematode worm C. elegans, a 1mm-long worm which has just 302 neurons compared to the estimated 86 billion neurons of a human brain. It is the only brain to be fully mapped by scientists.
What animal has 32 brains
Leech
Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
Do ants have a brain
Yes, ants have brains – albeit very small ones. An ant's brain has 250,000 neurons. Human brains, by comparison, have more than 100 billion brain cells. Despite the relative smallness of an ant's brain in comparison to humans, scientists consider the ant to have the largest brain of all insects.

Which animal has 11 brains
Silkworms have animal have 11 brains.
The brain, which serves as the silkworm's primary control centre, is situated in the centre of the head.

Who has more than 1 brain
Octopuses have nine brains!
In many ways, octopuses are the closest thing to having aliens on earth. These intriguing cephalopods are incredibly unique, boasting three hearts pumping blue blood. Perhaps more noteworthy, however, is the fact that these sea creatures have more than one brain.
Do jellyfish have brains
Do they have brains No, jellyfish have no single centralized brain. Instead, they have radially distributed nervous systems that are adapted to their unique body plan.
Which animal has 1,000 eyes
chitons
Although chitons look very simple, these mollusks have a very sophisticated shell. Its outer layer contains up to 1000 tiny eyes, each a bit smaller than the period at the end of this sentence.
Which animal has 25,000 teeth
Snails
Snails have more teeth than any animal.
This is TRUE. A snail's mouth is no larger than the head of a pin, but can have over 25,000 teeth (but these aren't like regular teeth, they are on its tongue).
Can ants feel pain
Insects do not have a visual cortex, for example, but there is no doubt that they can see. It is thus possible that insects may also experience pain, but underpinned by different neural circuits than mammals (e.g., multiple realizability and related theses: Chittka et al., 2012; Mallatt and Feinberg, 2021).
Do snails have brains
Snails like other invertebrates do not have a spinal cord nor one single brain. Instead they have a set of ganglia (groupings of neurons) that distribute the control of the various parts of the snail.
Who has 9 brains
Octopuses
Octopuses have NINE brains, with two-thirds of their vast knowledge spread throughout their arms.
What has 8 brains
Facts About How Octopuses' Brains Communicate with Each Other. Although octopuses have nine separate brains, they are still connected to and communicate with each other. The eight ganglia, or mini-brains, have their own neural ring that bypasses the central brain.
Which animal has 32 brains
Leech
Leech: Leech is an annelid. Leech's external and internal segmentation do not correspond to each other. If the internal body is examined, it can be seen that the body is divided into 32 parts or segments which have their own corresponding brain.
Which small animal has 32 brains
Leech
Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
Is pig IQ higher than dog
Pigs are gentle creatures with surprising intelligence. Studies have found they're smarter than dogs and even 3-year-old children! In the wild, pigs form small groups that typically include a few sows and their piglets.
How high IQ has a dog
The average dog's IQ is about 100. Based on the results done to test a dog's IQ, it turned out that dogs, even the average ones, have the IQ same as a 2-years old human.
What animal is cute and lazy
Koalas
Koalas are the cutest — and they also rank among the laziest! The adorable fur balls only wake for two to six hours a day! Like giant pandas, Koalas' near-constant state of slumber is food-related. Since most of their diet is eucalyptus, a super-high-fiber food, digesting it requires all the little koalas' energies.
What is the cutest bird
So the 10 cutest birds in the world are:Mountain Bluebird (Sialia currucoides)Goldcrest (Regulus regulus)Long-Wattled Umbrella Bird (Cephalopterus penduliger)Bee Hummingbird (Mellisuga helenae)Peach-faced love-birds (Agapornis roseicollis)ATLANTIC PUFFINS (Fratercula arctica)Cuban Tody (Todus multicolor)
Who have 12 brains
Answer: Elephant has 12 brains.
