Some animals (like horseshoe crabs) have blue blood because they use hemocyanin carry oxygen to their tissues instead hemoglobin like we do. The copper in the hemocyanin makes their blood appear blue.
Blood becomes blue when it is deprived of oxygen. These veins are returning de-oxygenated blood to the heart, making them appear blue.
some muscles are red and others are blue of your blood
once it comes into contact with oxygen it turns red.
Some crabs and lobsters.
well it depends on what if it is a human of cours not.insted you buy a tail and put it on. and if its an anymal it depends on what animal it is.
Most molluscs and some arthropods have blue coloured blood.
because they have copper in their blood instead of iron.
Not so sure but some spiders are known to have blue blood
No, penguins do not have blue blood. Penguins, like other birds, have red blood due to the presence of hemoglobin, which carries oxygen in their bloodstream. Blue blood is found in animals like horseshoe crabs and some mollusks due to a different type of oxygen-carrying molecule called hemocyanin.
The copper in their blood gives their blood a bluish tint. It is much like how iron in our blood causes our blood to be red. Haemoglobin is a red pigment in blood that makes the blood red when it comes out into oxygen (that why when we bleed, our blood is red.) some animals do not have haemoglobin in blood, for example LOBSTERS! So this is why their blood is blue.
"Blue blood" LITERALLY means blood that is blue in color.
Mammalian blood is NOT blue.
