Hint: The shade of the blood is because of respiratory colors, those liable for moving oxygen to cells all through the body and carbon dioxide to the lungs. As we as a whole know, human respiratory color is haemoglobin, which is found in red platelets or erythrocytes.

Complete step by step answer:
Here are a few creatures with green blood, for example, a few annelids (worms) , a few bloodsuckers, and some marine worms. Its respiratory shade, called chlorocruorin, gives its blood a light greenish shading when it is deoxygenated, and a little hazier when it is oxygenated. Basically, it is fundamentally the same as haemoglobin, since it likewise has an iron molecule at its middle. In contrast to haemoglobin, it isn't found in any cell however skims in the blood plasma.
In the instance of vertebrates with green blood (like some New Guinea reptiles) , the shading is expected to be biliverdin, which results from the debasement of haemoglobin. Biliverdin is harmful, however, these reptiles can withstand significant levels in their body. In the remainder of vertebrates, if biliverdin levels are high in light of the fact that the liver can not debase it to bilirubin, they cause jaundice, an illness that gives a yellowish tone to the skin and corneas of the eyes. Be that as it may, in types of reptiles like Prasinohaema prehensicauda, the high presence of biliverdin could ensure them against intestinal sickness, as indicated by some exploration.
So the correct answer is 'Chlorocruorin'.

Additional Information: Chlorocruorin is a dichroic red-green respiratory protein. It is synthetically like haemoglobin and is just discovered broken up in the blood of certain marine annelid worms. Chlorocruorin is the trademark blood color of the Serpulimorpha (serpulids and sabellids) , however in the class Serpula both chlorocruorin and haemoglobin are available together in the blood. This is the first occasion when those two respiratory colors have been found in the blood of one creature. Youthful people generally have more haemoglobin, the more established one's chlorocruorin. Inside the serpulid sort Spirorbis, one animal type has chlorocruorin in its blood, another has haemoglobin, while a third has neither shade. As their living spaces are comparative, no useful clarification for these distinctions presents itself. The oxygen partiality of all chlorocruorin tried is significantly lower than that of most hemoglobins.

Note: Chlorocruorin is known distinctly from blood, and from the mucous container of Myxicola; none has been found in cells. The coelomic liquid contains none. Protoderm is emitted into the defensive containers of both serpulids and sabellids. A proto hemochromogen is available in the gut liquid of serpulids, reviewing that found in shellfish and molluscs.
