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.
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.
Some crabs and lobsters.
because they have copper in their blood instead of iron.
Not so sure but some spiders are known to have blue blood
Most molluscs and some arthropods have blue coloured blood.
No, penguins do not have blue blood. An animal who does have blue blood is the lobster and lizards have green blood.
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.
Possibly, if they have some European blood in them.
