Oxygen and blood are most important for any human being to survive. But do you know what colour the blood is? Most people will answer that it is red. But do you know that apart from humans, animals also have blood of many colours other than red. Today we will tell you how many colours blood is found in.

blood has many colors

We all know that the blood of humans is red, the blood of many other creatures is also red. Apart from humans, the blood of vertebrates is also red, the reason for the blood being red is the protein called hemoglobin present in it. Most of the humans on earth have seen red blood. Because apart from humans, red blood is often found in animals as well. But apart from this, there are many creatures whose blood is of other colors. The iron ore present in the blood combines with oxygen to give it a red color, but there are also many creatures whose blood is blue, green and purple.

blue blood

The blood of sea creatures such as octopus, molluscs, squid, crustaceans and spiders is blue in colour. Instead of haemoglobin, haemocyanin flows in their blood. Haemocyanin contains more copper than iron and it turns the blood blue as soon as it comes in contact with oxygen.

green blood

Let us tell you that chlorocruorin is found in the blood of some small creatures. This sub-content, similar to haemoglobin, turns dark green as soon as it comes in contact with oxygen. It is usually found in insects that break down their bodies, such as leeches, earthworms and sea worms.

purple blood

Apart from this, hemerythrin substance is found in the blood of some organisms. It supplies much less oxygen than hemoglobin, it has no colour of its own. But as soon as it meets oxygen, it forms a purple or magenta colour and the blood of these creatures appears purple. The blood of some special marine organisms like Pinus worm, Peanut worm and Brachiopods is of purple colour.
