Interesting Facts
Insects have tiny brains with about 1 million neurons (while the human brain contains about 86 billion neurons).
At the same time, according to scientists, the largest brain on Earth has a marine mammal such as the sperm whale.
Its brain weighs on average 8 kg, and the animal itself weighs approximately 45 tons.
Nevertheless, the ratio of brain mass to body mass is approximately 1:5500.
American scientists have discovered that the greater the mass of the cerebral cortex and the number of neurons in it in an animal, the longer and more varied it yawns.
What kind of brain does an ant have

In fact, this is an ordinary nerve ganglion, consisting of three ganglia and built primarily from association cells designed to receive and think about information.

In addition, the jellyfish has a nervous system, but no brain.
One species of jellyfish can even sleep, this is a unique case when sleep appears in animals without a brain.
