Octopuses and horseshoe crabs have blue blood. This is because the protein transporting oxygen in their blood, hemocyanin, is actually blue. The blood of a vulcan is green, according to the story anyway, and this is presumably because the stuff that carries oxygen in the vulcan's blood is green.

Is the blood color blue?
Hemoglobin bound to oxygen absorbs blue-green light, which means that it reflects red-orange light into our eyes, appearing red. That's why blood turns bright cherry red when oxygen binds to its iron. ... But this is wrong; human blood is never blue. The bluish color of veins is only an optical illusion.
Why do blood looks blue?
Blood is always red, actually. Veins look blue because light has to penetrate the skin to illuminate them, blue and red light (being of different wavelengths) penetrate with different degrees of success. ... The oxygen-rich blood is then pumped out to your body through your arteries.
What is the true color of blood?
It's red because of the red blood cells (hemoglobin). Blood does change color somewhat as oxygen is absorbed and replenished. But it doesn't change from red to blue. It changes from red to dark red.
Can humans green blood?
If you have clear blood you may be a brachiopod, if you have blue blood you may be an octopus (or just a rich human), but if you have green blood you may have sulfhemoglobinemia.
Why is deoxygenated blood blue?
Share on Pinterest It is a myth that deoxygenated blood is blue; all blood in the human body is red. Human blood contains hemoglobin, which is a complex protein molecule in red blood cells. ... The iron reacts with oxygen, giving blood its red color. Although veins appear blue through the skin, blood is not blue.
What is the difference between blue blood and red blood?
Your blood gets its red color from oxygen. Your blood has this molecule in it called hemoglobin. ... when you're looking at your veins and arteries, the ones that look "blue" have blood without oxygen in them. The ones that look "red" have blood with oxygen in them.
Is blood blue or green?
Blood pumped directly from the heart is oxygen rich and bright red. As the blood circulates the body and oxygen is removed by tissue, the blood grows darker. For that reason, blood returning to the heart and lungs often has a dark red appearance. But it's never blue.
Why is my blood purple?
Oxygenated (arterial) blood is bright red, while dexoygenated (venous) blood is dark reddish-purple. The difference is color results from the electronic state of the iron ion (ferrous vs ferric), which in turn influences the π → π* and n → π* electronic transitions of porphyrin and hence its optical characteristics.
Is deoxygenated blood blue?
Blood that has been oxygenated (mostly flowing through the arteries) is bright red and blood that has lost its oxygen (mostly flowing through the veins) is dark red. Anyone who has donated blood or had their blood drawn by a nurse can attest that deoxygenated blood is dark red and not blue.
Can blood pink?
Pink Blood
This lighter shade usually means that the blood has mixed with your cervical fluid. Sometimes pink menstrual blood may indicate low estrogen levels in the body.
Can human blood be black?
The color of human blood ranges from bright red when oxygenated to a darker red when deoxygenated. ... Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated).
What has no red blood?
Octopuses, lobsters, and horseshoe crabs use hemocyanin, which has copper instead of iron, and is blue instead of red—that's why these creatures bleed blue. Other related molecules are responsible for the violet blood of some marine worms, and the green blood of leeches.
Why are veins blue in colour?
Veins appear blue because blue light is reflected back to our eyes. ... Blue light does not penetrate human tissue as deeply as red light does. As a result, veins that are close to the surface of the skin will be more likely to reflect blue light back to the eye.”
Why are veins blue and purple?
The blood going out to your body in the arteries is full of oxygen, which makes the blood bright red. But the blood coming back from your body in the veins is darker because your body parts have used up the oxygen in the blood. That's why veins look purple or blue.
Do any animals have blue blood?
Can you guess what animals might have blue blood? Lobsters, crabs, pillbugs, shrimp, octopus, crayfish, scallops, barnacles, snails, small worms (except earthworms), clams, squid, slugs, mussels, horseshoe crabs, most spiders. ...
