Blood
The colour of blood in human body is red. Apart from this, there are many animals in the world whose blood is also red. But you will be surprised to know that there are some animals on earth whose blood is not red but green, yellow and blue. Yes, today we will tell you how many colours of blood are present on earth.
Let us tell you that the reason for blood being red is the protein present in it called hemoglobin. The iron ore present in the blood gives it a red color when combined with oxygen, but there are many creatures whose blood is blue, green and purple.
The color of the blood of these animals is different
Octopus is a sea creature. People in many countries also eat it. You will be surprised to know that the blood of this eight-legged creature is blue in colour. The reason behind this is that the amount of copper is high in the blood of octopus, due to which the colour of its blood becomes blue. Apart from this, the creatures named ‘sea-cucumber’ may be green in appearance, but the colour of their blood is yellow.
The colour of the blood of the peanut worm is purple. Actually, when the protein called hemorithrin in the body of the peanut worm gets oxidized, its colour becomes purple or sometimes pink. Apart from this, the colour of the blood of the chameleon named New Guinea is green. This is the reason why the muscles and tongue of this chameleon are also green.
Crocodile icefish is found in the depths of Antarctica. The blood of this fish is colorless and transparent. Actually, the blood of icefish does not contain hemoglobin and hemocyanin. This is the reason why the blood of this fish has no color.
Why is the color purple
Let us tell you that hemerythrin substance is found in the blood of some creatures. It supplies much less oxygen than hemoglobin, it has no color of its own. But as soon as it meets oxygen, it forms a purple or magenta color and the blood of these creatures appears purple.
Why is the color green
Let us tell you that chlorocruorin is found in the blood of small creatures. This sub-content, similar to haemoglobin, turns dark green as soon as it comes in contact with oxygen.
Why is the color blue
The organisms in which haemocyanin flows instead of haemoglobin, their blood is blue in colour. This is because haemocyanin contains more copper instead of iron and it turns the blood blue as soon as it comes in contact with oxygen.
