Romulans have sulfur blood?
 
I think it's great that the devs have brought back a classic, though modified, creature from TOS. There's one problem though: if these creatures feed on copper based blood, they might want to chase after Andorians.
Copper based blood is blue, like that of an octopus, or possibly an Andorian. But Romulans, as well as Vulcans, have green blood, which means their blood is sulfur based. Even in the numerous Star Trek novels and information websites, Vulcan and Romulan blood is recognized as sulfur based. Please make the correction.

Vulcan blood and by extension Romulan blood was always known to be copper-based. If Star Trek used any science in blood color, then copper "rust" looks green just like iron rust appears red. Old buildings that used copper for their roof look green. So if you are correct in your assessment, then the people currently in charge of Star Trek would need to make the correction not Cryptic since Cryptic is going by what Star Trek has stated.

Vulcan blood was copper-based and was copper- or rust-colored when deoxygenated in the veins and green when oxygenated in the arteries (although it is unclear if this transport mechanism was a hemocyanin as in Earth molluscs). Bruises and dermal abrasions took on a greenish color. (TOS: "The Naked Time", "Patterns of Force"; DS9: "Field of Fire"; VOY: "Repression"; ENT: "In a Mirror, Darkly, Part II");

Copper-based blood is, in fact, blue. So Mr. Devencombs is correct. And if sulfur-based blood existed, it would probably be green.

The problem is that it's more important in fiction to be internally consistent than correct. Since it's already been established countless times that Vulcans and Romulans have green copper-based blood, any future Vulcans with blue blood, while being more accurate to real life, would break ST's own canon and therefore break the audience's immersion.

Just pretend ST takes place in an alternate universe where hemocyanin is green instead :)

The simplest explanation is that since The Original Series stated that Vulcans' blood is copper based and green when exposed to air, then it is established canon for Star Trek.

Besides, Hemocyanin is just what we know of on Earth. Who's to say that on Vulcan, or Romulus, there isn't some other copper carrying protein that looks more greenish?

Which ones? Both memory alpha (a repository for canon info) and memory beta (a repository for non canon info) state quite clearly that their blood is copper based.

Exactly. What is possible on Earth is not necessarily the same thing as what is possible on other worlds.

That's the presumption that they used in TOS when they were creating the explanation of the green blood. Just like iron oxide (rust) is red, similar to our iron-based oxygenated blood; copper-based oxygenated blood would be green, similar to copper oxide (copper "rust").

Sociology and culturally this might be true, but as far as chemistry and the laws of physics, those should be the same here on Vulcan, Andor, and the rest of the universe.

However, that completely doesn't rule out a different protein sequence for the Hemocyanin than that we use on Earth. Different evolutionary trees could lead to another Copper-based Hemo-molecule that looks greenish.

In any case, Canon > Logic :rolleyes: What has been established in canon outranks anything that we prove otherwise in reality. Any discrepancies between Science Fiction and Science fact can be attributed to alternate universes from ours and imagination. (This same train of thought that Star Trek isn't OUR future, but that of an alternate universe separate from ours takes care of several discrepancies, such as everyone on Earth missing the part where Khan ruled a quarter of it for some time in the late 20th century.)

However, more important is that the Canon is consistent with itself. (which, if you have ever read the Nitpickers guide to Star Trek, it happens alot.) However inconsistant that Trek is sometimes, one of the things that they are consistant on is that Vulcans, and Romulans, have Copper-Based blood AND they blood is Green when oxygenated.

On the Same topic, Does anyone else notice that Romulans fly around in blood-color ships :P How Morbid!
