Why does an octopus have 9 brains?
According to the Biogeo Planet, the octopus is considered the most intelligent creature because it has 9 brains. But how does an octopus utilises 9 brains? Actually, each of its eight brains helps in controlling the arm movements. And, the centre one for other activities.
Can octopus survive without one of their hearts?
The octopus would not be able to survive because that is the heart that provides the whole body with blood, which also helps deliver important oxygen around the body. If you thought three hearts was a lot, you might be even more surprised to learn about the hagfish, which looks kind of like a slimy, sticky eel.
Why do octopus have 9 hearts?
Octopuses have 3 hearts, because two pump blood to the gills and a larger heart circulates blood to the rest of the body. Octopuses have 9 brains because, in addition to the central brain, each of 8 arms has a mini-brain that allows it to act independently.
Do octopus have nine brains?
The giant Pacific octopus has three hearts, nine brains and blue blood, making reality stranger than fiction. A central brain controls the nervous system. In addition, there is a small brain in each of their eight arms — a cluster of nerve cells that biologists say controls movement.
What animal has 32 brains?
Leech Leech has 32 brains. A leech's internal structure is segregated into 32 separate segments, and each of these segments has its own brain. Leech is an annelid.
Which animal has 32 hearts?
Since octopus blood is very copper-rich, it's exceptionally viscous. As a result, it requires a significant amount of pressure to pump blood through its body. To compensate, the octopus evolved three separate hearts to take stress off of its systematic heart and ensure it gets enough oxygen into its gills.

Which animal has the highest IQ?
CHIMPANZEES CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
