What animal has 8 hearts? But their circulatory system is just as unusual. The octopus has multiple hearts, and that fact can reveal secrets about their evolutionary history while also informing our understanding of how they manipulate their environments. Here are all the facts you need to know about an octopus’ hearts.
Why do octopus have 3 hearts 9 brains and blue blood? But the octopus has a copper-based protein in its body called hemocyanin, due to which the blood turns blue. Hemocyanin does not blend with oxygen as easily as hemoglobin does. Because of this, two hearts pump blood through the gills, which get oxygen and blood, and the third heart pumps it throughout the body.
Do all octopus have 9 brains? In addition to a central brain located between the eyes, octopuses have separate “mini-brains” at the base of each of their eight tentacles. Unlike most creatures, octopuses have nine brains, and they put them to incredibly adept use.

Do giraffes have 2 hearts?
You surely know that humans and giraffes have just one heart, as most animals do—but not all. Octopuses and squids (animals called cephalopods) have three hearts. Two hearts pump blood to the gills to take up oxygen, and the other pumps blood around the body (Figure 1).
Do ants have hearts?
Ants do not breathe like we do. They take in oxygen through tiny holes all over the body called spiracles. They emit carbon dioxide through these same holes. The heart is a long tube that pumps colorless blood from the head throughout the body and then back up to the head again.
What animal has no brain?
Almost all animals have a brain, but there are a few exceptions. 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 color is giraffe blood?

How many brains does a dolphin have?
While most of us outside the scientific realm recognize that dolphins are intelligent, we do not know the intricacies of the dolphin’s brain. It has two hemispheres just like the human brain. However, theirs split into four lobes instead of three.
How many brains do jellyfish have?
Jellyfish have no brain!
They also have no heart, bones or blood and are around 95% water! So how do they function without a brain or central nervous system? They have a basic set of nerves at the base of their tentacles which can detect touch, temperature, salinity etc.
Does octopus feel pain?
Kristin Andrews and Frans de Waal posit in a new report published in the journal Science that many animals, including cephalopods such as octopuses, feel pain . But they don’t just react reflexively, like a child pulling away their hand from a hot stove. That type of reaction is known as nociception.
What animals Cannot feel pain?
Summary: Fish do not feel pain the way humans do, according to a team of neurobiologists, behavioral ecologists and fishery scientists. The researchers conclude that fish do not have the neuro-physiological capacity for a conscious awareness of pain. Fish do not feel pain the way humans do.
Do ants feel pain?
Over 15 years ago, researchers found that insects, and fruit flies in particular, feel something akin to acute pain called “nociception.” When they encounter extreme heat, cold or physically harmful stimuli, they react, much in the same way humans react to pain.
Do crabs scream when boiled?
Some say the hiss that sounds when crustaceans hit the boiling water is a scream (it’s not, they don’t have vocal cords). But lobsters and crabs may want to since a new report suggests that they could feel pain.
