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. ... Two hearts pump blood to the gills.

Do all octopus have 9 brains?
An octopus has up to 9 brains!
That is not all; this aquatic animal also has three hearts. Additionally, it does not have the normal red blood like you, and I have; an octopus has BLUE BLOOD flowing through its veins!
Does an octopus have one brain?
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. Octopuses have blue blood because they have adapted to cold, low oxygen water by using hemocyanin, a copper rich protein.
What does an octopus have 3 of?
Octopuses have three hearts, which is partly a consequence of having blue blood. Their two peripheral hearts pump blood through the gills, where it picks up oxygen. A central heart then circulates the oxygenated blood to the rest of the body to provide energy for organs and muscles.
Do all octopus have 3 hearts?
Octopuses have three hearts: one pumps blood around the body; the other two pump blood to the gills. The reason for this impressive cardiac hardware probably comes down to the unusual composition of their blood.
What animal has 32 brains?
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.
What animal has 8 hearts?
Currently, there is no animal with that amount of hearts. But Barosaurus was a huge dinosaur which needed 8 hearts to circulate blood upto it's head. Now, the maximum number of hearts is 3 and they belong to the Octopus.
What animal has no brain?
There is one organism that has no brain or nervous tissue of any kind: the sponge. Sponges are simple animals, surviving on the sea floor by taking nutrients into their porous bodies.
What animals have multiple brains?
Despite having a diffuse central nervous system with multiple brain-like hubs, octopi and cuttlefish make split-second decisions. When hunting or hiding, they quickly perceive their environment and coordinate different regions of their body independently to change colours.
Do octopus have multiple 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.
Where are the 3 hearts in an octopus?
Two of the hearts, called branchial hearts, are located near each of the octopus' two gills. They pump blood through the gills of the octopus. The third heart (called the systemic heart), then pumps the oxygenated blood through the rest of the body.
Which animal has largest brain in the world?
The sperm whale has the largest brain of any species. The brain weighs up to 20 pounds which is around 7 to 9 kilograms. Larger brains don't really make for a smarter animal, but the fact that bigger brains come up again and again as evolution happens says that bigger brains must be useful for something.
Can octopus have 9 legs?
A fisherman discovered a rare phenomenon while making dinner – one of the octopuses boiling in a pot had nine legs. The octopus, which has an extra limb emerging midway from one of its eight other legs, was found in Shizugawa Bay in the town of Minamisanriku, Miyagi Prefecture.
How many brains does an octopus have answer?
Thanks to their nine brains, it seems that octopuses have the benefit of both localised and centralised control over their actions.
Does an octopus feel pain?
A science-based report from the University of British Columbia to the Canadian Federal Government has been quoted as stating "The cephalopods, including octopus and squid, have a remarkably well developed nervous system and may well be capable of experiencing pain and suffering."
