I don't remember what animal it was, maybe penguins, but there's an air breathing animal that has something other than hemoglobin in its blood, that holds oxygen more efficiently, so they don't have to breathe for up to like, 2 hours or something. Not related to blood color, but still interesting and related to blood.

Hmm, so Spock's blood was based on known science?

It may have been. Some other aliens are. I went with cyanoglobin for Tim the Tentacle Monster because he is cephalopod-based.

Not quite, Spock's blood was supposed to be copper based not iron, but the only earthly copper-based blood is blue not green. So Roddenberry wasn't quite right. [assuming chemistry is even remotely similar in that universe.]

Copper can yield a range of blue to green colors, so I find copper-based green blood to be plausible. Alien blood probably is not identical to Terran blood.
