Predator: Why are hunter aliens green-blooded in the movies?

The Blood of the Yautja, the Predators of the Sci-Fi Horror Franchise The predator, it’s green. In price, this bioluminescent blood plays a key role. But after all, why is the body fluid this color?
A phrase became famous in predator: “If it bleeds, we can kill it”. both in predator how much in The Predator: The Huntthe Yautja can be tracked and killed through its distinctive green, glow-in-the-dark blood.

Of course, we can assume that the blood of the predator does not contain hemoglobin, which is the cause of the red pigmentation of human blood.
On Earth, there are animals that have green blood, which is due to the presence of chlorocruorin. But the Yautjas, however, are from very far away from our planet, so it seems unlikely that the same oxygen-binding protein is present in their blood.
The answer may even lie in the unique properties of the blood of the predator, whose cloaking technology gives them a huge advantage over their human opponents – which ends when their blood is spilled.
Alien vs. predator and Alien vs. predator 2 illustrate a key property of Xenomorph blood: a potent molecular acid with the ability to burn human flesh and bones.

It has been suggested, but not yet confirmed, that blood color may be an evolutionary quirk. The “Feral Predator” also had a distinctive mask, due to its evolution in a more desert environment than the other predators.
So far, all this remains only conjecture. What can, in fact, be said, is that the unique properties of the predators’ bright green blood still remain a powerful and compelling element within the franchise’s mythos.
